There’s a whisper that Fantech is about to unveil the latest development in apartment ventilation. The TD Silent range of mixed-flow fans incorporates a number of new technologies that make them very quiet.

Fantech Engineering Manager Kerry Dumicich said the revolutionary design was quieter than other similar products in the market and was a real advance in fan and acoustic technology.

“This breakthrough in noise reduction is due to a specially designed perforated internal skin. Sound waves produced inside the fan are directed through the perforations and are captured by a layer of sound-absorbent material,” Kerry said. “The result is outstanding, a fan that operates very quietly while at the same time maintaining efficiency”.

The most popular model, the TD-500/150 Silent has a sound pressure of only 33dB(A) at low speed and 40dB(A) at high speed. This makes it perfect as an extract fan in apartments, hotels, and offices where rooms are often close together and the constant sound of the ventilation system could distract the occupants.

Kerry said it was the small details that helped make the TD Silent so quiet. “The fan body is held in place with plastic straps at each end which form part of the mounting bracket. These straps grip onto a special ribbed rubber gasket on the fan body that further reduces vibration and noise” he said.

The inlet and outlet spigots also include a rubber gasket which helps to reduce air leakage when connecting to ductwork, making the duct system more efficient, but also absorbs vibrations which can sometimes be heard as noise. All these inbuilt innovations mean that in most cases there is no need for additional attenuation components to reduce noise.

Furthermore, its engineers have been able to include all this in a sleek, compact unit. The TD-500/150 Silent is 245mm high, making it ideal for installations in false ceilings or apartments where space is often restricted.

“The engineers have really thought of everything,” Kerry said. “The TD Silent range is more than just an innovative inner skin; its designers have considered where the fan will most likely be installed and what the limitations are.”

Conscious that installers often have confined spaces to work in, the distinctive body of the TD Silent can be easily removed from the support brackets by releasing its clips. These unique clips make removal simple for maintenance and cleaning. Another unique feature of this fan is its 360° rotating junction box that makes it easier to connect the power cable in tight spaces.

The TD Silent range of fans are now available from your Fantech office or agent. The range includes 150 and 200mm spigot diameter models.
