Make Up Air

How Dry Heat Works

Moisture control is a huge advantage of our dry-heat solutions. We configure our heaters to continuously draw in cool, dry outside air. This air is heated and forced into the building as hot, dry air that leaches the moisture out of concrete, drywall, paint and other finish construction materials. The resulting moisture-laden air is then forced out of the building through natural gaps in the building envelope. This process, called exfiltration, is facilitated by the positive internal building pressure created by the specially designed fans in our heaters.

Used to alleviate negative pressure situations in buildings and providing heat and drying, a make up air unit from Mobile Air can solve your temporary heating needs. Call us at (888) 474-4340 to learn more about make up air.
