How does it work a ductless system?

A ductless air exchanger is installed directly in the exterior wall of a building.

Unlike a ducted air exchanger, our units work like our own breathing.

For 70 seconds, one device evacuates air from the building while another device enters air into the building. After 70 seconds each unit reverses it operation, the evacuator becomes an air inlet while the other becomes an evacuator.

The cycle repeats itself constantly. At least two devices are needed in a building to ensure that the air pressure in the building is equal at all times.
