Mixed Flow In-Line Fan MFT100S

Continental Fan’s MFT100S is the 4-inch model in the MFT-S mixed-flow in-line series, designed for quiet, efficient duct boosting and general ventilation. The two-speed, single-phase motor delivers a maximum free-air performance of 146 cfm (≈248 m³/h) at high speed, with 109 cfm at low speed. The UV-resistant plastic housing and precision-balanced mixed-flow impeller reduce noise and vibration, while IPX4 protection and automatic reset thermal overload add durability and safety. The unit is suitable for air temperatures up to 140 °F, mounts in any orientation, and includes brackets for simple installation and service access to the motor and impeller. MFT100S fits standard 4-inch ducts and is appropriate for longer or more complex runs in residential or light commercial applications.
