Air handling units for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings. Heat recovery minimises ventilation heat losses. Control of air exchange for creating comfortable indoor microclimate. Compatible with round Ø 125 to 315 mm air ducts.


The casing is made of aluminium profile and double-skinned aluzinc panels, internally filled with mineral wool layer for heat and sound insulation. The casing has fixing brackets with vibration absorbing connectors for easy installation. The spigots for connection to the air ducts are located at the side of the unit and are rubber sealed for airtight connection to the air ducts. The hinged casing side panels ensure easy access to the internals for cleaning, filter replacement and other maintenance operations.


Asynchronous external rotor motors and centrifugal double-intake impellers with forward curved blades are used for air supply and exhaust. Integrated motor overheating protection with automatic restart. Dynamically balanced impellers. Equipped with ball bearings for longer service life. Reliable and quiet operation.


The built-in G4 supply filter and G4 extract filter provide air filtration.


Speed control by means of the four-position speed switch CDP-3/5 that enables setting low, medium, maximum speed and turning the unit off.

KOMFORT L 1200/2200


The unit is equipped with a plate cross-flow polystyrene heat exchanger for heat recovery. The unit condensate is collected and drained to the drain pan under the heat exchanger. The air flows are completely separated in the heat exchanger. Thus smells and contaminants are not transferred from the extract air to the supply air. Heat recovery is based on heat and/or humidity transfer through the heat exchanger plates. In the cold season supply air is heated in the heat exchanger by transferring the heat energy of warm and humid extract air to the cold fresh air. Heat recovery minimizes ventilation heat losses and heating costs respectively. In the warm season the heat exchanger performs reverse and intake air is cooled in the heat exchanger by the cool extract air. That reduces operation load on air conditioners and saves electricity. When the indoor and outdoor temperature difference is insignificant, heat recovery is not reasonable. In this case the heat exchanger can be temporary replaced with a summer block for the warm season (available as a specially ordered accessory).


The integrated automatic freeze protection is used to prevent freezing of the heat exchanger in the cold season. The supply fan turns off according to the temperature sensor to get the heat exchanger warmed up with extract air. After that the supply fan turns on and the unit continues to run in the standard mode.


Mounting to floor, ceiling or wall with fixing brackets. The correct mounted unit must provide condensate collecting and drainage and free access to the hinged side panel for servicing and filter replacement.
