Air handling units for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings. Heat recovery minimizes ventilation heat losses during cold season and reduce air conditioner load during hot season. Controllable air exchange for creating the best suitable indoor microclimate. Compatible with round Ø150 mm air ducts.


The casing is made of expanded polypropylene (EPP) 15-30 mm thick with high heat- and sound-insulating properties.


High-efficient external rotor EC motors and centrifugal impellers with forward curved blades are used for air supply and exhaust. EC motors have the best power consumption to air flow ratio and meet the latest demands concerning energy saving and high-efficient ventilation.

EC motors are featured with high performance, low noise level and totally controllable speed range. Dynamically balanced impellers.


Two built-in G4 and F7 filters provide efficient supply air filtration.The G4 filter is used for extract air filtration.

The KOMFORT EC D5B180(-E) models are equipped with a bypass which can be opened if there is a need to cool down the ventilated area with cool intake air. 


The KOMFORT EC D5(B)180 units have a counter-flow polystyrene heat exchanger that recovers heat. 
The KOMFORT EC D5(B)180-E units have a plate counter-flow enthalpy membrane heat exchanger that recovers heat and humidity. Due to humidity recovery the enthalpy heat exchanger produces no condensate. 

The air flows are fully separated within the heat exchangers. Odours and contaminants contained in the extract air are not transferred to the supply air flow. Heat recovery is based on heat and/or humidity transfer through the plates of the heat exchanger. 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 heat losses, which reduces the cost of space heating. In summer the heat exchanger performs reverse and intake air is cooled in the heat exchanger by the cooled extract air. This reduces load on air conditioners and saves electricity. 

The KOMFORT EC D5B180(-E) S21 units are equipped with a built-in automation system. The remote control panel is not included in the delivery set (sold separately). 
Unit control via Wi-Fi using the mobile application Blauberg AHU.
