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.

  • Single suction Ø 76 – Ø 85 mm aluminum impeller with forward curved constant thickness blades.

  • Housing made of pre-galvanized metal sheet, thanks to the high aeraulic efficiency it guarantees an excellent yield in terms of air flow, static pressure and low noise level.

* 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.
