Sundström SR 500 Powered Air Purifying Respirator (PAPR) Fan Unit

DATA SHEET

Product Overview

The SR 500 is a battery-powered fan that, together with a filter and an approved head top, forms a Sundström fan-assisted respiratory protective device system. It can be used as an alternative to filter respirators in all situations where these are recommended, and is particularly suited to work that is hard, warm or of long duration. Filtered air is fed through a hose to the head top, generating positive pressure that prevents surrounding pollutants from penetrating the mask.
