CSF4 Crawlspace Vent. Fan

Perfectly suited to distribute fresh air into stale areas to alleviate current or future humidity issues, the CSF4 is an AC-motored, durable ventilation fan.

With the motor in the airstream, the CSF4 series fan provides constant dissipation of heat build-up that gives the fan first-in-class longevity and reliability backed by an industry leading warranty.

The fan housing uses a large, electrical wiring enclosure to make electrical installation easier. This airtight fan ensures that contaminants do not spill because of leakage and it can be mounted in indoor, outdoor, and damp locations. Best suited for non-encapsulated crawlspaces.

The housing is manufactured from two molded, plastic pieces. The unique, vibration welding process uses reciprocating motion at the point of contact to join the two halves and create a single housing. The fused seam is inherently airtight and permanent.

The fan’s motor bearings are permanently sealed and self-lubricating for maintenance-free life.

Choose from a variety of duct accessories to make your installation straightforward and time efficient.
