This versatile Inline fan features a plastic housing constructed of UL-recognized, UV-protected thermoplastic resin. This tough protective shell allows the fan to be mounted in wet locations. Ideal for multiple point exhaust, dual head exhaust, or other marine applications, Delta “T” Systems’ inline fans are caulked at the motor screws, the wiring cables and along the seams of the fan to prevent moisture from entering the housing.
