Powered air purifying respirators, filtering respiratory protection

Powered air purifying respirators are the highest level of filtering respiratory protection. Contrary to classical gas masks, they are positive pressure devices. It means that the respiratory effort is lower because it is not made by the wearer but by a motor sending a constant flow of filtered air into the face piece (mask, hood, welding screen). It is, therefore, better to use devices for strenuous, tiring, long-duration work or interventions in environments with high heat.

Powered air purifying respirators

Powered air purifying respirators are more elaborate filtering respiratory protection devices. They are composed of a face piece (mask, hood, welding shield), one or more respiratory protection filters (particulate, anti-gas, or combined), a light motor, and a ringed hose. A motorized fan delivers the filtered air directly into the face piece via the corrugated hose leading to a lower breathing effort. The main advantage of a positive pressure filtering respiratory protection system is the reduction in breathing effort.

Therefore we would prefer using powered air purifying respirators for strenuous, tiring, long-duration work or interventions in hot environments. In addition, the overpressure generated in powered air purifying masks guarantees a nominal protection factor much higher than with a conventional gas mask.

Hoods & powered air purifying respirators

PAPR hoods

Hoods are manufactured in a flexible material, resistant to certain corrosive gases. They cover the whole head and have a wide field of vision. The powered air purifying hoods have an air distribution device for more comfort.

PAPR hoods

Powered air purifying masks

Powered air purifying respirators are the preferred facepiece when polluting concentrations exceed 40 times the OEL (8-hour occupational exposure limit value). The air sent through the powered air purifying respirator arrives directly near the respiratory tract, avoiding drying of the ocular mucous membranes.

PAPR masks

The filtration performance of powered air purifying respirators depends on the tightness of the complete device (face piece, motor, and filter). A letter (hood family) associated with a number (tightness level of the powered ventilation device) indicate them.

Tightness is measured as the percentage of leakage of "polluting gas" into the facepiece. The "polluting particles" are designated by the letters PSL (for solid and liquid particles) without mentioning an efficiency class:

TH (Turbo Hood) for hood-type facepieces

  • TH1 stops 90% of aerosols (i.e. 10% penetration)
  • TH2 stops 98% of aerosols (i.e. 2% penetration)
  • TH3 stops 99.8% of aerosols (i.e. 0.2% penetration)

TM (Turbo Mask) for facepieces such as mask or half-mask

  • TM1 stops 95% of aerosols (i.e. 5% penetration)
  • TM2 stops 99.5% of aerosols (i.e. 0.5% penetration)
  • TM3 stops 99.95% of aerosols (i.e. 0.05% penetration)

Limits of use of powered air purifying respirators

Do never use filtering respiratory protection under the following conditions:

  • Ambient oxygen level < 19%
  • In confined spaces or all areas with little or no ventilation: tanks, tunnels, boat holds, etc.
  • When the concentration of the contaminant is unknown or immediately lethal to humans (IDLH)
  • When the concentration of the contaminant is above the maximum allowable concentration or beyond the capacity of the filter

In these situations, it will be necessary to use an self-contained breathing apparatus.
