TD-350/125-T SILENT
Description
The S&P TD-350/125-T SILENT In-Line Fan is an ultra-quiet mixed-flow duct fan designed for use with 125mm circular ducting. Delivering an airflow of up to 330m³/h (91.7l/s), it provides effective ventilation while maintaining a low sound pressure level of just 23dB(A) at three metres.
An integrated adjustable run-on timer allows the fan to continue operating for between 1 and 30 minutes after the connected switch has been turned off. This helps remove remaining moisture, stale air and odours from the ventilated area. The timer version uses a single-speed motor and is not suitable for connection to an external speed controller.
The fan features a specially designed internal lining that directs sound waves towards sound-absorbent material, helping reduce operational noise. Rubber gaskets at the inlet and outlet help absorb vibration and provide an airtight connection to the adjoining ductwork. Its low-profile construction makes it particularly suitable for installation within ceiling voids and other confined areas.
The connection box can be rotated through 360° to simplify wiring, while the detachable motor-body assembly allows maintenance to be completed without disconnecting the ductwork. The TD-350 SILENT range is also certified by the Noise Abatement Society.
