The SR 580 Loose Fitting Hard Hat together with the SR 500 belt-mounted Powered Air-Purifying Respirator (PAPR) protects against particulates, gases and vapours, or a combination of both. 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 SR 580 Loose Fitting Hard Hat. The above-atmospheric pressure generated prevents surrounding pollutants from penetrating into the breathing zone.
