The installation of an Make-up air unit is the most efficient way to maintain indoor air quality by diluting airborn contaminants with outside fresh air. Also, the addition of Airextube flexible supply air duct named will eliminate the air stratification often seen in high open areas thus reducing significantly the energy consumed to heat the space.
The outside air is drawned up through the filtered hood and passes in a serie of controlled dampers and tempering device using gas or electricity to produce energy. The tempered air then goes through the high efficiency fan to be redirected in the distribution/destratification air supply duct.
