Sundstrom SR 500 PAPR

Sundstrom SR 500 PAPR

The Sundstrom SR 500 PAPR System is a belt mounted powered air-purifying respirator with tight fitting face pieces, loose fitting respirators or loose fitting hoods that protect 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 respirator or loose fitting hoods. The above-atmospheric pressure then generated prevents surrounding pollutants from penetrating into the breathing zone. This PAPR used lithium ion batteries with a charging time of around 2 hours which will provide up to 13 hours of operating time. It is equipped with two filters/combined filters and automatic air flow control. The same control is used for starting, stopping and selecting the operating status, making it simple to use.
