Q: What type of battery is used with the North Compact Air PAPR?
A: Nickel Metal Hydride (NiMH).
Refer to this FAQ’s section on Batteries for more information.


Q: Are peel-away windows available?
A: Yes. There are 3 sheets per set, 5 sets per package
• 7600 & 5400 Series Facepieces: North part number 80836A
• Primair Plus Hoods: North part number PA105



Q: Can I use the tight fitting blower/battery with a hood?

A: No. The tight fitting and loose fitting blower battery assemblies are NOT interchangeable. Use of the Compact Air PAPR in any configuration not listed on the NIOSH Approval Label could affect the flow of air to the facepiece or hood – providing either too much or not enough air. It would also void the NIOSH approval.


Q: What is the difference between the tight fitting (CA102) and loose fitting (CA101) versions?
A: There are two main differences.
• The amperage of the battery 
o CA101: 9 amp battery to deliver a minimum of 6 CFM to the hood or loose fitting facepiece
o CA102: 7 amp battery to deliver a minimum of 4 CFM to North’s tight fitting facepieces
• The breathing tube
o CA101: straight breathing tube to fit the Primair Series head covers
o CA102: ‘Y’ breathing tube to fit North’s tight fitting facepieces


Q: How can I tell the difference between the tight fitting (CA102) and loose fitting (CA101) versions?
A: The blower and battery housings are color coded.
• CA101: blower & battery is black with yellow trim  
• CA102: blower & battery is blue with yellow trim. The ‘Y’ connector on the breathing tube is also blue.

Q: What is the advantage of Saranex coating?
A: Saranex coating provides some chemical resistance. It is not chemical proof and should not be used where a full chemical suit is required.


Q: Are replacement hoods available?
A: Yes. Both Primair and Primair Plus replacement hoods are available
Primair Series replacement hoods


Q: Why does the Primair Series include a headgear?

A: Use of a headgear helps to keep the head cover secure on a worker’s head. The integrated manifold directs air over the lens.


Q: Why is it important to direct air over the lens?

A: Air delivered to the front helps to keep workers cooler and more comfortable, plus it eliminates fogging on the inside of the lens. Air directed to the front also means that the air is not hitting the back of the head where it can be uncomfortable for the worker.


Q: Is the headgear adjustable?

A: Yes. There are three adjustment points including a ratchet system so workers can obtain a secure and comfortable fit.


Q: How do I adjust the headgear?

A: Refer to the Primair Users’ Instructions.

North Compact Air Cartridges & Filters, Service Life & Shelf Life

Q: What filters and cartridges are available for use with the North Compact Air?
A: The Compact Air PAPR offers several chemical cartridges and filter combinations
Filter
40HE High Efficiency Particulate Air-Purifying (HEPA) Filters
Chemical Cartridges
4001 Organic Vapor
4003 Organic Vapor, Chlorine, Hydrogen Chloride, Sulfur Dioxide, Hydrogen Fluoride, Chlorine Dioxide, Hydrogen Sulfide (escape)

4003HE Organic Vapor, Chlorine, Hydrogen Chloride, Sulfur Dioxide, Hydrogen Fluoride, Chlorine Dioxide, Hydrogen Sulfide (escape) with HEPA filter
4004HE Ammonia / Methylamine with HEPA filter
PAPR filters and cartridges


Q: When do I change my filters?
A: Filters are changed when you start to notice a drop in air flow. Use your air flow indicator to test whether filters need to be changed. As the filters get clogged, less air passes through and thus less air is delivered to the facepiece or hood.

 40HE HEPA filter for Compact Air PAPR.


Q: When do I change my cartridges?

A: Cartridges must be changed based on a site specific cartridge change schedule. North’s esLife™, part of our ezGuide™ software program, helps users develop objective change out schedules for gas and vapor cartridges. North is in the process of updating this guide to include our PAPR cartridges. Meanwhile, OSHA accepts historical data as a basis of a change schedule.

Determining change schedules based on historical data.
Take the lowest breakthrough time for a worker in a specific site, with specific conditions (temperature, humidity, contaminant concentration, etc), and multiply it by a safety factor (OSHA recommends 80% and EPA recommends 60%). Use this number as the change time. The longer you record data, the more reliable the change time will be for the employee working at that site. Data recorded for several employees at that site can then be generalized into a single change time for that site.

For more information on OSHA’s recommendations visit their web site: http://www.osha.gov/SLTC/etools/respiratory/testing/testing.html

Q: Do North Compact Air PAPR filters and cartridges have a shelf life?
A: No. As long as the filters or cartridges have been stored in a clean, dry environment, away from excessive heat or cold they are fine. Snap the blue caps provided with your filters or cartridges back on when storing.


Q: Must I use all three filters or cartridges, or can I plug one hole and only use two?

A:  You must use all three filters or cartridges.
First, only using two air purifying elements would void NIOSH approval.
Second, using the PAPR in any configuration other than as approved by NIOSH would affect the air flow delivered to the hood or facepiece and could result in injury to the worker.
 
North Compact Air Battery

Q: What type of battery is used with the North Compact Air PAPR?
A: Nickel Metal Hydride (NiMH).


Q: Why is a Nickel Metal Hydride (NiMH) battery better than a Nickel Cadmium (NiCad) battery?
A:  NiMH batteries do not have a memory so recharging is easier and faster. They are lighter weight. But most importantly NiMH batteries do not diminish in power during operation, unlike NiCad batteries which will gradually lose power during the day.


Q: How many hours of use can I get from the North Compact Air PAPR?
A:  Service life is dependent on environmental conditions. However, a minimum of 8 hours is typical if the battery is fully charged when you first start to use the unit. The exact time of service may vary.


Q: Will the air flow of the North Compact Air PAPR start to diminish as I use the unit?
A:  North’s Compact Air PAPR features a nickel metal hydride (NiMH) battery which delivers an even power supply through the entire work period.

You may notice a decrease in air flow during the course of the work period if you are using a HEPA filter or cartridge filter combination. This is caused by the loading of the filter with particulates. When air flow has decreased to the point that less than 4 CFM is delivered to the facepiece or 6 CFM is delivered to the loose fitting head cover, then is it time to change the filters. Exit to a clean environment and check your air flow with the air flow indicator provided with your unit.


Q: How do I tell when the battery needs to be charged?

A: The power delivered by Compact Air’s nickel metal hydride (NiMH) battery will drop off suddenly and significantly, indicating that the battery needs recharging. There will not be a gradual loss of power prior to this. Any minor loss of air flow during the course of the work period is usually an indication that the filters need to be changed.


Q: Do I need to charge my battery before using the Compact Air PAPR for the first time?
A: No. The North Compact Air PAPR is shipped with the battery preconditioned and fully charged.


Q: How quickly can I recharge my battery?
A: The Compact Air PAPR uses a nickel metal hydride (NiMH) battery which can be recharged in six hours or less, depending on several factors including how much service life was left in the battery.


Q: Do I need to run the battery down prior to recharging?

A: No. The nickel metal hydride (NiMH) battery of the North Compact Air PAPR does not have a memory, so you do not need to run the battery down prior to recharging.


Q: Can I leave my battery on the charger overnight or over the weekend?
A: Yes. The North Compact Air PAPR battery features a thermister or “trickle” charge which allows you to leave the battery on the charger for extended periods.
Caution:
not all PAPR batteries feature a trickle charge, so if you are not using a North PAPR, check the manual of your specific unit.


Q: Do I need to remove the battery from the backpad to recharge?
A: No. The battery can be connected to a charger while still mounted on the backpad, or you can remove it from the backpad, allowing the unit to stay in service with a freshly charged battery.


Q: How do I know when the battery is fully charged?
A: When the green light on the charger is lit. The red light is lit when the charger is still recharging.


Q: How many times can I recharge the North Compact Air PAPR battery?
A: Over 200 times. Exact number of charges may vary depending on several factors, including the amperage at your site.

Decontamination

Q: Can I wear North’s Compact Air PAPR in a “decon” shower?
A: Yes. North offers a “decon” version for PAPRs for use with tight fitting facepieces and for loose fitting head covers. Add the suffix ‘D’ to either unit for the “decon” version.

CA101D: Compact Air with “decon” PVC backpad and belt, for loose fitting head covers
CA102D: Compact Air with “decon” PVC backpad and belt, for North facepieces

Compact Air with PVC belt and backpad.


Q: What is the difference between the standard North Compact Air PAPR and the “decon” version?

A: The standard Compact Air features a nylon belt. The “decon” version features a polyvinyl chloride (PVC) backpad and belt. Otherwise they are the same.


Q: Can I wear my North Compact Air PAPR while going through a “decon” shower if I use High Efficiency Air-Purifying (HEPA) filters?
A: Yes. Compact Air PAPR HEPA filters are hydrophobic – that is they repel water, so the filters can be subjected to the shower spray of a “decon” shower.

HEPA filters 40HE were tested after exposure to moisture and passed DOP* penetration, indicating that the filters are indeed hydrophobic, thus allowing filters to be reused as long as they have not reached the end of their service life. Because the carbon of combination cartridges would be affected by exposure to water, it is recommended that these cartridge filter combinations be discarded after having been exposed to spray from a “decon” shower.
*DOP: Dioctylphthalate. The challenge oil aerosol used to test filters. DOP is used because it is the most degrading substance known to NIOSH.


Q: Can I wear my North Compact Air PAPR while going through a “decon” shower if I use chemical cartridges alone?

A: No. The chemical cartridges are not water resistant. But, you can go through a “decon” shower safely if you use a chemical cartridge HEPA filter combination since the Compact Air PAPR HEPA filter is hydrophobic. You must always discard your cartridge/filter combinations after they have been exposed to excessive moisture.


General Questions about Powered Air-Purifying Respirators

Worker with Compact Air PAPR shown with 7600 Series Facepiece.


Q: What is a PAPR?

A: PAPR are initials for Powered Air-Purifying Respirator. It is, as its name indicates, an air-purifying respirator that has a battery powered blower.
OSHA Definition: An air-purifying respirator that uses a blower to force the ambient air through air-purifying elements to the inlet covering.


Q: How does a PAPR work?

A: A powered air-purifying respirator uses a blower powered by a battery to pull ambient air through cartridges, filters or a canister. A constant flow of clean air is delivered to the facepiece or hood.
The blower can be belt mounted or facepiece mounted. The battery is always mounted on the belt. When the blower is mounted on the belt it can be separate from the battery, or they can be integrated into a single case. The battery may be rechargeable or non-rechargeable, supplying power for 4 to 8 hours depending on the model.


Q: What are the differences between a PAPR and an APR?

A:  PAPRs use a blower and battery: Air-purifying respirators (APR) remove contaminants from the ambient air with either filters, cartridges or a canister (air purifying elements). With APRs the air is pulled through the air-purifying elements as the worker inhales. Powered air-purifying respirators (PAPR) utilize a blower to pull the ambient air through the air-purifying elements.

  • PAPRs have a constant flow of air: The blower supplies a constant flow of air to the worker.
  • PAPRs have a positive pressure inside the hood or facepiece: Standard air-purifying respirators have a negative pressure inside the hood or facepiece. The constant flow of air generated by the PAPR blower creates a positive pressure inside the hood or facepiece.
  • PAPRs have a higher Protection Factor: Because of the positive pressure created by the flow of air, PAPRs have a higher protection factor.

Q: What are the advantages of a PAPR over an APR (air-purifying respirator)?

A:  Some of the benefits of PAPR are:

  • Less worker fatigue: Because the air is pulled through the filters or cartridges by a blower, rather than the inhaled breath of the worker, the worker does not tire as quickly.
  • A flow of air is delivered to the worker: A constant flow of air is delivered to the facepiece or hood. While this air is not cooled, the effect of the air does cool the worker.
  • Higher protection factors: Because a PAPR has a positive pressure rather than a negative pressure inside the hood or facepiece it has a higher protection factor than its comparable APR version.


Q: What are the disadvantages of a PAPR over an APR (air-purifying respirator)?

A:  Higher initial cost: A PAPR respirator costs significantly more than an air-purifying respirator. This initial cost can be offset by increased worker productivity.

 Additional weight: The blower and battery add weight. Belt mounted PAPR units put this weight on the waist, and are thus less noticeable. In some models a PAPR may actually appear to weigh less and be more comfortable to the worker, as cartridges are mounted on the belt and not the facepiece.


Q: What are the advantages of a PAPR over a SAR (supplied air respirator)?

A:  Less initial cost: Supplied air respirators require a pump or a compressor with filtration system, hoses and couplers that add to the initial cost of set-up.

No hoses to drag around: A powered air-purifying respirator is self contained, with the battery and blower worn by the worker. A supplied air respirator utilizes hoses which limit the worker’s mobility.

Q: What are the disadvantages of a PAPR over a SAR (supplied air respirator)?
A:  Higher operating cost: Powered air-purifying respirators use cartridges or filters that need to be changed on a regular schedule. Supplied air respirators do not use air-purifying elements, saving the cost of replacing these filters or cartridges.

Additional weight: A PAPR requires a worker to wear a blower and battery, adding weight to the unit.


Q: What is the difference between a belt mounted and a facepiece mounted PAPR?
A:  Both have a battery that is worn on the belt. The difference is where the blower is mounted. On a belt mounted PAPR the blower is on the belt, either integrated into the housing with the battery or separate. On a facepiece mounted PAPR the blower is located on the facepiece, usually next to the filter or filters.


Q: What are the advantages of a belt mounted PAPR?
A:  Better weight distribution: The blower is located on the belt rather than the facepiece, so the weight is distributed where it is easier to carry, rather than pulling on a worker’s neck.

Hoods and tight fitting facepieces: Because of the weight of the blower, facepiece mounted PAPRs can not accommodate hoods or other loose fitting head covers.

Chemical cartridges and HEPA filters: Facepiece mounted PAPRs are only available with HEPA (high efficiency particulate air-purifying) filters, since the weight of a chemical cartridge mounted on the facepiece would be too great for this style of PAPR.


Q: What are the disadvantages of a belt mounted PAPR?

A: Breathing tube: Belt mounted PAPRs have a breathing tube to deliver the supply of air. When positioned in the front this tube can get in the way. North has solved this problem with the unique ‘Y’ breathing tube that goes over the worker’s back, out of the way of the work zone.


Q: Which PAPR is right for me, belt mounted or facepiece mounted?
A:  Both are NIOSH approved. Which one you chose depends in part on the job requirements. Facepiece mounted PAPRs are only available with full facepieces and HEPA filters. If you require chemical cartridges or desire a hood, than you need to use a belt mounted PAPR. 
 
Some people prefer facepiece mounted PAPRs because it eliminates the breathing tube, which can get in the way of the work zone. North’s Compact Air belt mounted PAPR uses a unique ‘Y’ breathing tube that goes over the worker’s shoulders, taking the breathing tube out of the work zone.


OSHA & CSA Regulations Pertaining to PAPRs

Q: What are the Assigned Protection Factors (APF) for Powered Air Purifying Respirators (PAPR)?
A: Assigned Protection Factors for PAPRs are higher than comparable air-purifying respirators (APR), and generally the same as comparable supplied air respirators (SAR).
Note: There are disagreements between agencies (OSHA, NIOSH, ANSI and CSA) as to specific APFs. For more information, visit our page on Assigned Protection Factors.
View APF (Assigned Protection Factors) Chart


Q: How much CFM (Cubic Feet per Minute) does the Compact Air PAPR deliver to the facepiece or hood?
A: The amount of air will vary depending on the filter or cartridge used, and whether the filter is new or near the end of its service life.
Tight fitting facepieces: 4 CFM minimum is required by OSHA.
Hoods and other loose fitting head covers: 6 CFM minimum as required by OSHA


Q: How do I check for the correct air flow?

A: Use the flow meter provided with the North Compact Air PAPR, replacement part number CA132.

-For Compact Air PAPR with a straight breathing tube: With the unit turned on, insert the flow meter in a vertical position at the end of the breathing hose. Check the ball in the airflow meter. It must be above the line marked 6 CFM or 170 LPM.

-For Compact Air PAPR with the ‘Y’ breathing tube: With the unit turned on, insert the flow meter in either of the swivel connectors on the breathing hose and block off the other with the palm of your hand. Check the ball in the air flow meter. It must be above the line marked 4 CFM or 115 LMP.

Q: How do I perform a User Seal Check (aka Positive Pressure Seal Check) on a North Compact Air PAPR?
A: Tight fitting facepieces: With the facepiece donned and the blower on, test for positive pressure inside the facepiece by gently breaking the facepiece seal at your cheek. Airflow should be heard and felt. If you feel it, allow the facepiece to reseal. If you do not feel and hear airflow a positive pressure has not been obtained.

If you can not obtain a positive pressure refer to the section on Trouble Shooting.


Performing a Positive Pressure Seal Check.

Hoods and loose fitting head covers: It is not necessary to perform a positive seal check on hoods and loose fitting head covers.

For more information on the use and maintenance of North’s Compact Air PAPR refer to the Users’ Instructions.
PAPR User's Instructions


Q: Do workers who wear a PAPR need to be fit tested?

A: Tight fitting facepieces: Yes, if the workers are at or above the contaminant’s Permissible Exposure Limit (PEL). Below the PEL use of a respirator is voluntary and fit testing is not required. Hoods and other loose fitting head covers: No, fit testing is not required.


Q: Because a PAPR provides a positive pressure inside the facepiece I don’t need to fit test - right?

A: Wrong. Fit testing is required on any tight fitting facepiece when worn at or above the Permissible Exposure Level (PEL).


Q:  I need to fit test my workers who wear PAPRs. Can I perform a Qualitative Fit Test (QLFT) or is a Quantitative Fit Test (QNFT) required?
A:  Qualitative Fit Testing is the minimum requirement for Powered Air Purifying Respirators.


Q:  How frequently do I need to fit test my workers?
A:  In the United States fit testing is required at least annually. In Canada fit testing is recommended annually, and required every two years.

Exceptions:
• Some contaminant specific regulations (such as lead and asbestos) that require fit testing every six months.
• Some Canadian Provinces have additional fit test requirements. Check your local regulations.
• When the worker has any change to the facial structure that will affect the fit.
You need to have a complete understanding of all fit test requirements for your specific site.


Q: Can I use a surrogate mask to perform fit testing?

A: Yes. But it is not necessary with the North Compact Air PAPR.
A surrogate mask may be used as long as the mask has the same fit characteristics as the actual mask that will be worn (material, size, facial seal design). However, the adaptability of the North APR to PAPR system allows workers to be fit tested wearing their own mask. Additional adapters or a surrogate mask are not needed.


Q How do I perform Qualitative Fit Testing (QLFT) on a PAPR?

A:  QLFT needs to be performed with the facepiece in a negative pressure mode. To put the unit in a negative pressure mode you need to either (1) turn the unit off and have the worker breathe through the air purifying elements without the use of the blower; or (2) use the mask in the APR configuration. The adaptability of the North APR to PAPR system allows workers to be fit tested wearing their own mask. Additional adapters or a surrogate mask are not needed.


Q How do I perform Quantitative Fit Testing (QNFT) on a PAPR?
A:  Like qualitative fit testing, quantitative fit testing (QNFT) needs to be performed with the facepiece in a negative pressure mode. Currently there are two types of quantitative fit testing methods available, the Controlled Negative Pressure Protocol (Dynatech) and the Generated Aerosol Quantitative Fit Testing Protocol (TSI Porta-Count). The adaptability of the North APR to PAPR system allows workers to be fit tested with either method while wearing their own mask. The standard APR adapters for the specific QNFT method are required. The adapter for the Porta-Count is North part number 770021. Contact Dynatech for information on the appropriate adapter for their fit test apparatus.


Q: Which PAPR can be worn by workers with facial hair?

A:  A PAPR with loose fitting head covers is the only type you can use. (North’s Compact Air CA101 or CA101D with Primair Series head covers). OSHA forbids any facial hair between the face and facepiece seal. 


Q: My workers use a hood / loose fitting head cover (Primair Series). Do they still need additional eye protection?
A:  Yes. The visor or faceshield of a PAPR’s hood or loose fitting head cover is not considered primary eye protection. Additional protection of a safety spectacle that meets the ANSI/CSA Standards is required.
North Safety Eyewear


Q: When is an intrinsically safe PAPR required?
A:  An intrinsically safe PAPR is required whenever you have a very high concentration of particulates, which creates a risk of explosion. Coal mines, some pharmaceutical facilities and grain silos are a few examples.


Q: Does the North Compact Air meet the UL/ULC requirements for most industrial applications?
A:  Yes. North’s Compact Air PAPR is UL listed for the United States and Canada, meeting the requirements for the majority of industrial applications. But the North PAPR is not intrinsically safe, a requirement for a select number of applications.


Q: Is the North Compact Air PAPR NIOSH approved?
A: Yes. The Compact Air is NIOSH approved for use with North’s 5500, 7700, 5400 and 7600 Series air-purifying masks, and for use with North’s Primair Series hoods and head covers. NIOSH approval for the Primair HD is pending.

Q: Why do Powered Air-Purifying Respirators use HEPA filters when all other air-purifying respirators use other classifications of filters like N95 and P100?
A:  When the NIOSH Standard 42 CFR Part 84 was introduced, powered air-purifying respirators were exempted. As a result, the filter classification for PAPR is still referred to as HEPA (an acronym for High Efficiency Particulate Air-Purifying).


Q: North’s Compact Air PAPR has a standard 40mm DIN thread. Can I use another manufacturer’s 40mm threaded cartridges or filters with this unit?
A: No. Use of any other manufacturer’s parts, including cartridges and filters will void the NIOSH approval.


Q: Is there a NIOSH approved PAPR for CBRN (Chemical, Biological, Radiological and Nuclear) respiratory protection?
A: No. The NIOSH Standard for a CBRN PAPR is still under review. Once it is finalized and published, then manufacturers will be able to design a unit to meet this Standard and submit it for approval.


Q: Is there a new NIOSH Standard for PAPR?
A: No. NIOSH has announced that there will be a revision to the Standard CFR 42 Part 84 regarding PAPR. The proposed changes will go through a formal review process, with a projected completion of 2007. Until then the current Standard applies.


Q: NIOSH is changing the Standard for PAPRs. Are units sold today still OK to use?
A: Yes. As long as the PAPR has a current NIOSH TC Approval number, it is OK to use the unit.

Troubleshooting North Compact Air PAPR

The PAPR fails to turn on
• Battery is not charged. Recharge the battery or use a new battery that is fully charged
• The switch on the battery is in the “off” position. Push the switch to turn it on.
• The power cord between the battery and blower is not connected or is broken. Reconnect the cord. If it still does not work and you suspect the plug or cord is damaged, replace the blower.

The PAPR supplies insufficient airflow
• The battery is near the end of its charge. Recharge the battery or use a new battery that is fully charged
