View additional information tab for specifications and technical information.

The TT Silent Inline fan is a fantastic new product we now have available. It is specifically designed for a very quiet operation and a great option for subfloor ventilation systems. It features a built in 50mm layer of mineral wool sound insulation which ensures a quiet operation without compromising on its performance. With a capacity of 555m3/hr on high, and a dBA rating of only 26 on low, these specifications set this fan apart from others on the market.

The inner casing perforation lets sound waves pass through to the sound-absorbing layer. The internal casing is sound-insulated with a 50 mm mineral wool layer. The TT Silent Mixflow inline fan with its specially perforated casing and sound-absorbing material provides sound attenuation in a broad frequency band. The inner casing and the impeller are made of high-quality durable plastic.
