TD-350/125
Description
The S&P TD-350/125 Standard In-Line Fan is a compact mixed-flow duct fan designed for use with 125mm circular ducting in residential and light commercial ventilation systems. Delivering an airflow of up to 330m³/h (91.6l/s), it provides effective extraction while its low-profile design makes it suitable for installation within ceiling voids and other areas where space is limited.
The two-speed motor provides a choice of 250m³/h or 330m³/h, allowing the airflow to be selected according to the ventilation requirements of the installation. The motor can also be used with a compatible voltage speed controller where further airflow adjustment is required.
Manufactured with a reinforced polypropylene casing and an ABS mixed-flow impeller, the TD-350/125 offers a durable yet lightweight construction. Its integrated support bracket allows the motor and impeller assembly to be removed for inspection or maintenance without disconnecting the adjoining ductwork, helping simplify installation and ongoing servicing.
