FB-A Ultra


FB-A Ultra plus with High-Performance Fan

 Air capacity up to 4255 m³/h

Powerful, quietly running radial fan

 Heating capacity up to 80 kW

Like FB-A Ultra and in addition

Enormously powerful

Type „Ultra plus“ of series FB-A is extending series Ultra by a diagonal fan unit for hightest air capacities.

with high-performance fan

with especially quietly running external rotor motor with speed control  possible up to double air capacity  high compression possible  with duct connection frame

Due to diagonal air flow and favourable sound behaviour, the FB-A Ultra plus ceiling units can used wherever the capacity of FB-A Ultra units with their low pressure axial fans isn‘t sufficient any more. Ultra plus will make it even for larger rooms without efforts - and especially quiet. Moreover, the special scoop shape of the fan wheel is extremely energy-saving.

All FB-A units with suction above

Ceiling air unit with recirculating air

Ceiling air unit with mixed air attachment parts Outside air suction through the wall The recirculating air outside air amount is adjusted by the mixed air part. Outside air suction horizontally through the outside wall. Recirculating air suction by recirculating air suction grid.

This procedure reduces heating costs, using partially already heated air out of the heated room, and on the other hand provides the necessary fresh air. In outside air operation, the air is sucked directly from outside for heating or cooling. In suitable circumstances, this procedure guarantees clean and unspoilt air.

Air Guidance Ceiling Air Units by Suction Duct Air suction by suction grid in intermediate ceiling Air suction by recirculating air suction grid, suitable for grid ceilings 625 x 625.

In recirculating air operation, the air is sucked out of the room to be heated and blown back into the same room after being heated. This procedure causes lowest operating costs.
