TT Silent M 100 is Vents‑US’s 4-inch inline mixed‑flow fan designed for quiet residential or light‑commercial ventilation. The metal, sound‑absorbing casing and aerodynamic impeller reduce noise while maintaining performance. This 120 V/60 Hz model features a two‑speed, ball‑bearing motor with a built‑in speed switch and thermal overload protection. At 0 in. w.g., it delivers up to 128 CFM (≈217 m³/h) through 100 mm ducting, making it suitable for utility rooms, small grow tents where space and low noise are priorities. The unit ships with a mounting plate and power cord for straightforward installation. Typical applications include duct boosting and exhaust where a compact, vibration‑free fan is required. The series is ETL certified and backed by a 2‑year warranty.
