Particle-filter fan unit SR 700

Particle-filter fan unit SR 700

The SR 700 is a battery-powered fan that, together with particle filter SR 510 P3 R or SR 710 P3 R and an approved head top, is included in the Sundström fan-assisted respiratory protective device systems. The SR 700 can be used as an alternative to filter respirators in all situations in which these are recommended. This applies particularly to work that is hard, warm or of long duration.
The fan is equipped with filter, and the filtered air is fed through a hose to the human interface. The pressure then generated prevents surrounding pollutants from penetrating into the mask.

The characteristics of the SR 500 are as follows:

• The battery is of lithium-ion type
• The charging time is around 2 hours
• Equipped with two particle filters
• Operating time of up to 8 hours
• The same control is used for starting, stopping and selection of operating status
• Display with symbols
• Alarm with audible/visual signals if the air flow is obstructed
• Equipped with automatic air flow control
• Can be used together with hoods SR 520, SR 530, SR 561, SR 562, face shield SR 540, half mask SR 900, full face mask SR 200, welding shield SR 590, helmet with visor SR 580 or welding shield/helmet with visor SR 584/SR 580

Electronics ingress protection is approved in IP class IP67 according to IEC / EN 60529.
