TF/FF Series
Cross-Flow Fans are particularly indicated for uses where, in limited space, high air volume is required with low noise and regular air-flow.
The FF series provides an additional fixing option through 4 + 4 extensions placed directly on the side.
16 – 54 W
0,13 – 0,42 A
80 – 364 m3/h
Technical specifications
-
Single phase, 2-shaded poles, impedance protected motor, built according to the CE mark requirements, in compliance with EN 60335-1 standard, with self-aligning and self lubricating sleeve bearings with big oil reservoir.
-
Motor with minimum 130° “B” insulation class.
-
Suitable for continuous operation in ambient temperature from -10 °C to +50 °C.
-
Electrical connection by 6,3 x 0,8 mm, radial or axial, male faston-type connectors, directly fixed on coil.

* IV version
Impregnated coil through dip-coating using epoxy transparent paint (standard stator coil dip-coating process).
* IM version
Impregnated coil through dip-coating using transparent epoxy paint with silicone applied on contacts at the end of winding, three-pole wire and coil covered by a nylon cap. The coil is not drowned in the resin but visible; caution should be paid when mounting the motor so that the cap open part faces downward to prevent its filling up with condensate.
* INC version
Coil with IP55 protection, the coil is completely drowned into the epoxy resin.
