Roof fans
TFDX 315-355
• Speed-controllable
• Integral thermistors
• Vertical exhaust
• Tilting frame included
• Maintenance-free and reliable
The TFDX models have impellers with backward-curved
blades and maintenance-free external rotor motors. The
casing is manufactured in galvanised sheet steel, with a
brass or copper inlet cone. Powder-coated version available
on request. The fan has a tilting mechanism for easy
inspection and servicing. Exhaust air is directed vertically
from the fans which prevents problems caused by wet
snow and staining of the roof.
To protect the motor from overheating these fans have integral
thermistors with external leads which should be connected
to the TUS 230 KIL motor protection relay.
Explosion proof versions comply with EN 50014 and
50019. Improved safety in accordance with EEx e ll T3.
