S&P TD SILENT

The S&P TD SILENT fans are the quietest duct fans on the market and are designed for ventilation of residential, commercial and industrial buildings where low fan noise is a requirement. The S&P TD SILENT silent duct fans are made of plastic or, for larger diameters, metal. A great advantage of the S&P TD SILENT circular duct fans is that the motor part of the fan can be removed without disconnecting the ductwork.

The S&P TD SILENT two- and three-speed duct fans can be controlled by changing the voltage using electronic controllers (e.g. REB), the fans with EC-saving motors can be controlled by 0-10V potentiometers. The fans can be mounted in any position. The housing of the TD SILENT duct fan must not transmit mechanical stresses from the ductwork, we recommend using a circular a VBM mounting clamps.
