Sundström SR500 Powered air purifying respirator kit + SR561 hood

Package with fan unit SR 500 and respiratory hood SR 561.

The SR 500 system is a belt mounted Powered Air-Purifying Respirator (PAPR) with 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.

Characteristics fan unit SR 500

Characteristics hood SR 561

The hood together with the battery-driven SR 500, SR 500 EX or SR 700 fan and approved filters are included in Sundström fan-assisted respiratory protective devices. The breathing hose of the hood is connected to the fan which is equipped with a filter. The pressure generated in the hood prevents particles and other impurities from being admitted into the hood. The hood can also be used with the SR 507 compressed air equipment. This combination forms a breathing apparatus designed for continuous air flow, for connection to a compressed air supply. The equipment can be used as an alternative to filter protections in all situations in which the latter are recommended. This applies particularly to situations in which the work is intensive, hot or of long duration.
