Efficient exhaust ventilation systems - Without heat recovery

Efficient exhaust ventilation system with manual air flow control or intelligent air flow control

  • Exhaust air units are the most cost-efficient method of mechanical ventilation.
  • Exhaust air units consume less electrical power because only the fan needs energy.
  • However: no heat recovery and no pre-heating of supply air

The used, humid and polluted room air in extract air rooms such as kitchens, bathrooms and toilet rooms is extracted by a fan through a duct system and led via roof or facade to the outside. Fresh air enters living rooms, children‘s rooms and bedrooms via facade or windows inlets (valves with filter in the facade or window frame with integrated supply intake) and ensures continuous airing of the whole apartment. The controlled room ventilation reduces ventilation heat losses compared to conventional airing by open windows.

 


 

We deliver demand-controlled EC fans as well as complete duct systems including extract air valves, silencers and exhaust air outlets for roofs or facades.

Fresh air inlets in the facade are also available with noise reduction; demand-control of the ventilation unit is available with CO2 or humidity sensors.
