5.5 Fan and motor data
• Max. temperature of transported air, max. ambient temperature, sound pressure –> see data sheet, available in our
online catalogue.
• Voltage, current, enclosure class, weight –> see name plate
• The motor data can be found on the name plate of the motor, or in the technical documents of the motor
manufacturer.
5.6 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 10.
• The maximum permissible operating data on the name plate apply for an air density of 1.2 kg/m³ (sea level) and
a max. air humidity of 80 %.
• The fans are exclusively intended for extract air applications.
DVN, DVNI
• The fan is suitable for conveying contaminated air
(dust, kitchen exhaust), with a density of 1.3 kg/m3
and a max. air humidity of 95 %.
DVS, DVSI, DVC, DVCI, DHS
• The fan is suitable for conveying clean air, with a
density of 1.3 kg/m3 and a max. air humidity of 95
%.
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
• Operation without duct system or protection grille
• Operation with the air connections closed
