HE740 - roof mounted exhaust fan

  • DACS Video Channel

The HE740 exhaust fan has outstanding efficiency rating and it is by far the most energy efficient roof mounted exhaust fan available.

In a direct comparison against leading suppliers on the market, the HE740 exhaust unit offers at least 30 % lower energy consumption at equivalent flow rates. E.g.: 25.5W/1000 m3/h @ 17,471 m3/h.

Two versions - turning baffle or butterfly damper
The HE740 exhaust with butterfly damper completely seals off from rain, birds, insects, rodents and light when not in operation. This unit is for on/off operation.

The HE740 with turning baffle can be speed controlled via frequency inverter, or via on/off operation.

Motors for both HE740 versions are UL/ULc listed and can run on both 50Hz and 60Hz power grid.
