TT Silent M 200 is an 8-inch inline mixed-flow fan from Vents-US designed for quiet, high-pressure duct applications. A metal, sound-insulated housing and an aerodynamic impeller reduce noise while maintaining airflow. The integrated two-speed AC motor with thermal overload protection is rated for long life, and the unit includes a mounting plate and power cord. At free air, maximum airflow is 473 CFM (≈804 m³/h), with a built-in speed switch providing a lower setting when needed. The fan is ETL certified for 120 V/60 Hz operation and supports air temperatures up to 140 °F. Typical uses include grow rooms and light commercial spaces where noise control matters, and it fits standard 8-inch round ducts.
