5 Description
5.1 Intended use
All roof fans
• The fans are intended for installation in ventilation systems. They can be installed both in duct systems and also
with free suction via an inlet cone and a suction-side contact protection grille. Systemair recommends a Back draft
damper (VKS) to avoid cold air intake at a standstill of the fan, see 7 Accessories, page 9.
• The fans are exclusively intended for extract air applications.

DVN, DVNI
• The fan is suitable for conveying contaminated air
(dust, kitchen exhaust).
Incorrect use
Incorrect use refers mainly to using the fan in another way to that described. The following examples are incorrect
and hazardous:
• Conveying of explosive and combustible media
• Conveying of aggressive media
• Operation in an explosive atmosphere
DVS, DVSI, DVC, DVCI, DHS
• The fan is suitable for conveying clean air.
• Operation without duct system or protection grille
• Operation with the air connections closed
5.2 Technical data
Max. ambient temperature [°C]
see data sheet, available in our online catalogue.Max. temperature of transported air [°C]
Sound pressure [dB]
Voltage, current, frequency, enclosure class, weight see name plate of the fan
The motor data can be found on the name plate of the motor, or in the technical documents of the motor
manufacturer.
