The Vents-US TT Silent M 125 is a 5-inch (125 mm) inline mixed-flow fan built for quiet ventilation in higher-pressure duct runs. Its metal, sound-absorbing casing and aerodynamic impeller are designed to limit noise while maintaining airflow. On 120 V/60 Hz power, the 125 model provides up to 188 CFM, approximately 320 m³/h, and includes a built-in two-speed switch. A long-life ball-bearing motor (rated up to 40,000 hours) and ETL certification support durable operation. The unit integrates with 5-inch ducting and ships with a mounting plate and power cord for straightforward installation. Positioned within the Turbo Tube Silent M series, the 125 size offers a compact footprint with strong performance for utility spaces and grow rooms where quiet airflow is important.
