Crawlspace exhaust fans pull stale air, heat, odors, and some moisture out of basements and crawlspaces. The fans mount into existing ventilation openings in building foundations.

Crawlspace supply fans continuously pull fresh air into basements and crawlspaces. They are commonly used in spaces with stagnant air or spaces where exhausted air needs to be replaced more quickly than what would naturally occur through louvers and other openings. The fans mount into existing ventilation openings in building foundations.

Crawlspace reversible fans can be used to exhaust stale air, supply fresh air, or simultaneously exchange stale air for fresh air. Fans are rotated to change the direction of airflow individually for each fan to force stale air out of spaces or pull fresh air into spaces. The fans mount into cutouts on rim joists or walls.

These duct connector kits are used to connect compatible crawlspace reversible exhaust and supply fans to ductwork in applications where the fans are pulling air from outside the area where the fan is mounted.

These dehumidistats connect to compatible crawlspace reversible exhaust and supply fans to turn the fans on or off based on the humidity levels in the surrounding area. The dehumidistats can be set to activate when a particular humidity threshold is reached, or they can be set to continuously operate the fans.
