It uses a durable, UV‑resistant plastic housing with a precision‑balanced impeller for quiet operation and includes mounting brackets for easy installation. The MFT125S fits 5 inch (125 mm) ducts and is suitable for supply or exhaust applications, long duct runs, and air temperatures up to 140 °F. It carries an IPX4 rating and features automatic reset thermal overload protection with permanently lubricated ball bearings. On high speed, the MFT125S delivers a maximum airflow of 200 cfm (approximately 340 m³/h). Typical uses include duct boosting and general ventilation where compact, low‑noise performance is required.
