SR 500 Air-Purifying Respirator

$ 1,249.00 $ 1,301.00

The SR 500 system is a belt mounted Powered Air-Purifying Respirator (PAPR)  that protects the user from breathing in particulates, gases and vapors, or a combination.

Designed for use in oxygen sufficient and non-immediate danger to life and health (IDLH) environments. The SR 500 PAPR system functions as an alternative to Air Purifying Respirators (APR) in all situations for which these are recommended. This applies particularly to work that is hard, warm or of long-duration. The filtered air is supplied through a breathing hose to the tight fitting face piece, loose fitting respirators or loose fitting hoods. The above-atmospheric pressure then generated prevents pollutants from the surroundings from penetrating into the breathing zone.

The characteristics of the SR 500 are as follows:

• The battery is of lithium-ion type 3.6 Ah
• Charging time around 2 hours
• Equipped with two filters/combined filters
• Operating time of up to 13 hours
• The same control is used for starting, stopping and selection of operating status
• Display with symbols
• Equipped with automatic air flow control with compensation for air pressure and temperature
• Can be used together with a hood, face shield, full face mask.

The filtered air, with its consistent positive air flow, provides a comfortable and reliable respirator that can be used in normal conditions as well as conditions that are strenuous, warm, or of long duration. The above-atmospheric pressure generated by the respirator prevents surrounding pollutants from penetrating into the breathing zone.

Our SR540 helmet and SR580 hard hat are rated Z87+. You should see a sticker on the helmets themselves. As far as HEPA, our filters are 100% NIOSH rated which is the same as ANSI rating. Our filters actually filter 99.997% of all HEPA, which is 10 times more than Niosh requires (99.970%)
