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. The motor protection is provided by customers. For speed control use only combination of frequency inverter and appropriate filter to motor side (sine or du/dt), observing instalation conditions (e.g. cable type, lenght). In case of fire eventual frequency inverter and all motor 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). When choosing AES control accessorie please observe serial connecting capability of the service switch of the DVV fan (instructions). Higher connecting capability on request.
Note (for EU market only): not affected by efficiency provisions of Commision Regulation (EU) No 327/2011 - exception 3 (c) (i) (a).
Please note: Speed controll by voltage, i.e. voltage transformers, is not possible!
In accordance with Commission Regulation (EC) no 640/2009 of the European Parliament - eco-design requirements for electric motors - the new international efficiency classes are binding as of 16 June 2011. These guidelines defined by CEMEP and EPACT are regarded as international standard for energy-saving high-efficiency motors for frequencies of 50 or 60 Hz and make the use of IE2 motors mandatory.
With this new and more efficient technology we offer our customers many advantages such as environmentally friendly operation, reduced energy consumption and hence lower emissions. IE2 motors have a higher efficiency even in part load operation and allow optimum adjustment to the operating point. In addition, the IE2 motors generate less noise and develop less heat, which has a positive influence on the efficiency and the cooling requirement of the motor. Please note: IE2 motors cannot be speed controlled by voltage, i.e. voltage transformers.

The smoke and heat exhaust roof fan 400 degree/120 min, vertical blowing. The DVV radial fans are intended for the extraction of hot flue gases in the case of fire as well as for the normal daily ventilation. They are suitable for installation on roofs on heated buildings - snow load class SL 0.
The base plate and the inlet cone are made of hot-dip galvanized steel sheet. The outer octagonal casing from seawater-resistant aluminium (DVV 1000D4-M and P from aluzinc steel sheet). Bird protection grill inside casing. The air stream is carried out through annular space between the casing and the motor housing. The fan has an electroplated backward curved radial impeller made of steel sheet, single inlet. With hub and secured bolted joint directly assembled on the motor shaft. Dynamically balanced according to ISO 1940 T1 quality class G6,3.
Driven by an IE2 high efficiency motor, single-speed, PTC thermal protection serial built-in. Cooling of the motor with ambient air through an isolated air duct in underpressure system. The motor protection is provided by customers. Connection the fan to the mains in service switch outside on the cooling duct. For speed control use only combination of frequency inverter and appropriate filter to motor side (sine or du/dt), observing installation conditions (e.g. cable type, lenght). In case of fire eventual frequency inverter and all motor 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).
Flange connection according to DIN 24154R3. The DIBT- approval number: Z-78.11-167. Tested according to EN 12101-3 at the TU Munich. CE-Certification according to EN 12101-3:2002-06, by TÜV SÜD. An additional sound attenuator HSDV is available on enquiry (the marking of fan is DVVI). With FSL accessories snow load class SL 1000 can be achieved (for DVVI on request only).
