Fantech FR100 4 Inline Centrifugal Duct Fan

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