Due to the nature of respirator products, we cannot take returns of open respirators.

The SR 500 system is a belt mounted Powered Air-Purifying Respirator (PAPR) which is  paired with either tight fitting face pieces, loose fitting respirators or loose fitting hoods that protects against particulates, gases and vapors, or a combination. It is designed to be used in oxygen sufficient and non-immediately dangerous 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 SR 570 face shield is a modern, innovative product, designed and developed based on the needs and requirements from the market. The SR 570 is a robust shield with a flip-up visor, and gives the user comfortable and safe respiratory and eye protection. The face shield is fitted with an attachment for hearing protectors. A wide range of accessories enable the user to customize the shield for their work situation. The shield is manufactured in a material that permits use in tough environments. The SR 570 shield can be used with our SR 500 PAPR.

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

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 SR570 face shields 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%)
