ROBUR F KM is a heating and ventilation unit designed for indoor operation. It is the easiest way to create a mechanical ventilation system in the building.

Combining the unit with air duct installation makes it possible to distribute warm air into the selected areas of the room. Use of the mixing chamber ensures air exchange in heated room.

Unit with radial fan ensures high efficiency. Burner which is made of stainless steel reaches 92 % of efficiency and reduces NOx emission.

Combustion chamber ensures safety and long, reliable operation due to assembly with exchangers without welding.

The floor effect, which is achieved through the special design of the heat exchanger, effectively keeps the warm air in the zone occupied by the people and limits significant temperature stratification in the room.

The heaters have as a standard equipment a summer/winter operating mode switch with integrated signalling and alarm reset and a set of nozzles for liquid gas.

There are various types of chimney packages recommended for the heaters – horizontal, vertical, concentric and separate. Various elevation endings – protective caps are available.


The KM F series heaters are designed for heating buildings with medium and big cubatures like sports centres, industrial halls, warehouses, shopping areas etc.


The F KM unit is equipped with control system, which controls throttles of mixing chamber and also can control roof fans (if provided).

The basic control system consists of:
• power and control board,
• proportional throttles actuators,
• throttles opening degree adjuster.


Construction – modular design. Unit is equipped with cassette filters, which filter the air supplied into the room (separate filters of the fresh and recirculated air).
