Model Overview

The TD-SILENT fans are extremely quiet, low profile "Mixed-flow" fans manufactured in tough reinforced plastic material, a single-speed controllable 115V 60Hz motor and an external connection box. Sound waves are directed through the perforated inner skin and absorbed by a layer of sound-absorbent insulation. These fans are fitted with rubber gaskets on the inlet and outlet to facilitate installation, absorb vibrations, and provide a virtually air-tight seal.

The TD-SILENT offers the same simple installation features as the extremely popular TD-MIXVENT fans with an integral mounting bracket, removable body, and a terminal box that can be rotated 360 degrees. The low profile of the fans makes them the ideal product for installations with low height limits, such as the case of suspended ceilings.

5-year fan housing and motor warranty
