The TD Silent series features a perforated design on the internal surface that directs sound waves towards sound-absorbing material. This effectively dampens noise, making these fans ideal for spaces such as growing areas where a quiet working environment is required. With a noise measurement of up to 17dBa, the TD Silent, recognized as the world's quietest duct fan, carries the Quiet Mark certification awarded by the UK Noise Reduction Association. Models TD 350, TD 500, TD 800, TD 1000, and TD 2000 are available.
Two-speed fan motors with speed control are rated Class B and IP44 protected. They feature ball bearings and overload protection. The fan's low profile provides advantages in narrow spaces such as attics and suspended ceilings. The perforated internal surface of the fans directs sound waves towards sound-absorbing material and dampens the sound. Thanks to the unique body design, you can open the interior of the fan without removing it from the duct to clean the motor and blades and perform maintenance. The electrical connection terminal can rotate 360° around the fan for convenient connection of power cables. Clamps located in the connection throats facilitate installation, while rubber seals dampen vibration and ensure airtightness. The fans have a double-material hanger mount to prevent motor vibration for wall or ceiling mounting. The fans are made of plastic material.
