Exhaust Fan – 145 CFM – Internal Mount
These double fans are designed for vent openings that fall between joists. This is typical in a West Coast or California construction. These fans can be mounted from the inside of the crawlspace to fit between the joists. If necessary, the fans can also be mounted with a cover from the outside when space is particularly tight. One benefit of internal mounting is that unique or aesthetic vent covers can remain untouched. If needed, a grill can be provided to cover vent opening. The fans can be powered via low voltage 12V DC wire from ATMOX controls or with an AC Adapter for a standard outlet.
