DVN / DVNI…D F4 - The NEW smoke extract fans for roof mounting
ruck Ventilatoren is pleased to introduce you the first smoke extraction fans!
The new DVN / DVNI…D F4 series are certified for temperature class F400 according to the european production and test standard DIN EN 12101-3.
They allow conveyor temperatures of up to 400 °C / 2 h and 200 °C for continuous operation.
Thus, these fans are suitable for smoke and heat extraction in case of fire, as well as for daily ventilation.
The housing made of seawater-resistant aluminum, with base plate and inlet nozzle made of galvanized sheet steel has an integrated grease collecting tray with drain. The housing of the DVNI series is thermally and acoustically insulated.
The built-in IE3 premium efficiency standard motors are outside the air stream, according to VDI 2052, and have a shaft seal which prevents the penetration of oil and water over the shaft.
The fans of this series are continuously controllable via frequency converter (IP66).
The backward curved radial impeller is provided with a Taperlock clamping bush which ensures improved balancing quality and higher operational stability.
