The SR 500 is a battery-powered fan unit that, together with filters and an approved human interface, is included in the Sundström fan-assisted respiratory protective device systems.
The SR 500 can be used as an alternative to filter respirators 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 human interface. The above-atmospheric pressure then generated prevents pollutants from the surroundings from penetrating into the human interface.
The same control is used for starting, stopping and selection of operating status (air flow 175 or 225 l/min).
Tested and approved according to EN 12941:1998 och EN 12942:1998
