Description
The TD Silent Series of low-profile mixed-flow in-line fans incorporates a break-through in noise reduction resulting in units that operate very quietly. The low noise levels are achieved through the technically advanced design of the internal construction, which does not impede on the air flow performance of the fan.
There are 6 models in the series, ranging from 100 to 315mm diameter spigot sizes.
Features
High performance mixed-flow impeller.
Low noise operation.
Vibration absorbing elements are integrated into the advanced body design.
360° rotating junction box makes connection of power cable easier (applicable for 100, 125, 150 and 200mm sizes only).
Integral mounting foot makes installation more simple.
1 to 30 minute run-on timer available on 100 to 200mm models.
Includes plug and lead for easy installation.
Convenient 2-speed motor, factory set to high speed (single speed on models with run-on timer).
Fan body can be easily removed without disturbing connected ductwork.
