The DVV smoke extract fans are used in case of fire to extract smoke gases from rooms, and also during normal working conditions for standard ventilation.

 

Smoke-free escape ways increase the chances to rescue people in case of a fire. For installation only on top of heated buildings.

 

The octagonal casing is manufactured from seawater resistant aluminium (DVV 1000 M and P 4 pole from aluzinc steel sheet). The base frame consist of galvanised steel. The impeller with backward-curved blades is manufactured from galvanised steel.

 

Motor cooling with fresh air via air duct. Thermal motor protection (PTC or thermal contact built-in) on request. For frequency controlled units PTC must be ordered. Service switch serial on cooling duct at sizes 800 and 1000. Other sizes equipped with terminal box, service switch on request. For two speed fans (up to 4 kW) two speed switch is available as accessories (in this case thermal contact must be ordered; not suitable for PTC or without thermal contact). In case of fire eventual two speed switch, frequency inverter and all protective devices must be bridged to guarantee functional capability (connection direct to mains). At frequency controlled units additional EMC protection could be needed (on request).

 

Note: in case of dual use (normal ventilation + smoke and heat extract) of single speed 4 or 6 pole fan with nominal power 0,75 kW or more EU legislation requires IE2 high efficiency motors; these items are marked with DVV.....IE2!
