Self supporting aluminium frame construction with highly impact resistant PA6 corners. 20 mm glass wool acoustic and thermal insulation. Integrated condensation tray with built-in 1” drain plug.


Depending on the version, equipped with voltage controllable IEC standard motors (DV and E4) or frequency inverter controllable IE2 standard motors (D2, D4 and IE2).

Impeller geometry

Optimised and highly efficient backward curved high density impellers from aluminium for optimum efficiency.

Output control

Speed controllable via voltage reduction using a transformer, or controllable with a frequency inverter.

Motor protection

Integrated thermal contacts or PTC thermistors with cables for connection to a motor protection switching device.
