Exhaust and Fresh Blower / Installation

Exhaust ventilation work by depressurizing the building; fans create negative pressures into the living space, which brings outside air into the building through dedicated vents or, in many cases, through leaks in the building envelope.

Supply ventilation, on the contrary, work by pressurization; it sucks outside air into the building, creating positive pressures and causing inside air to leak out through holes, cracks and openings, or through ducts and vents, if any exist, or through open windows and outlets.
