TT Silent M 250 is Vents‑US’s 10-inch, sound‑insulated mixed‑flow inline fan for high‑pressure residential and commercial ventilation. The metal outer casing with internal acoustic damping houses a double‑speed, ball‑bearing motor and aerodynamic impeller to reduce vibration and noise while maintaining strong airflow. The 250 mm duct connection integrates into round duct systems, and the body mounts on an included bracket for flexible orientation and service. On 120 V/60 Hz, maximum airflow is rated at 880 CFM (about 1,495 m³/h) at 0 in. w.g., with built‑in two‑speed switching. Typical applications include grow rooms and other spaces where quiet extraction through long duct runs is required. ETL certification and manufacturer support are provided through Vents‑US.
