Ventilation and Air Recirculation
MARK products for recirculating warm air from roof level, roof extraction and adiabatic cooling in suitable conditions.

Start with the air problem
Recirculation, extraction and cooling solve different problems. Choose an application to see how the system works and what information a selection needs.
Destratification fans
Warm air accumulates beneath a high roof while the occupied zone stays cooler. Explore ECOFAN W and P for recirculating existing indoor air.
Roof fans and general ventilation
Indoor air needs a planned route out, with replacement air provided alongside extraction. Explore the workshop scenario and MARK MDV BLUE.
Adiabatic cooling
A large production hall needs cooler supply air. Explore where outdoor temperature and humidity make MARK COLDSTREAM suitable.
What if the need is fresh air with heat recovery?
Consider air handling and heat recovery as a separate system choice. ECOFAN recirculates air; it does not supply outdoor air.
