TD-1300/250SIL Silent In-Line Mixed-Flow Fan

250 mm Ø | 352 L/s Free Air | 47 dB(A) @ 3m

The TD-1300/250SIL is a high-capacity 250 mm mixed-flow in-line fan designed to provide strong airflow performance while maintaining the low-noise characteristics of the TD Silent range.

With a free-air performance of 352 L/s, the TD-1300/250SIL is suited to larger ventilation and air movement applications where both airflow capacity and reduced operating noise are important.

The fan incorporates an aerodynamic inlet, mixed-flow impeller and vibration-absorbing design to help provide efficient, quiet operation.

High-Capacity Construction

Unlike the smaller 100–200 mm TD Silent models, the TD-1300/250SIL is a high-capacity unit manufactured from durable sheet steel.

Its aerodynamic inlet helps improve airflow, while the internal design provides the noise reduction and vibration control characteristic of the TD Silent range.
