The S&P TD-160/100N Silent is the top solution for residential and commercial ventilation in spaces where quietness is of primary importance, such as bedrooms, offices, and libraries. It is an inline duct fan that combines the advantages of axial and centrifugal fans, offering powerful airflow even in systems with several meters of ductwork. Its smart design allows the main body to be detached from its base with simple movements, making cleaning and maintenance easy without the need for tools or dismantling the duct network.

This technology is based on mounting the motor on special elastic pads (silent-blocks), which fully absorb vibrations before they are transferred to the external casing. In this way, the structural noise usually caused by the operation of the motor is eliminated, ensuring that the ventilator remains almost silent even at maximum rotation speed. It is the ideal choice for installations in false ceilings where the resonance of materials can amplify sounds.

The internal casing of the ventilator features a specially designed perforated surface that directs sound waves towards the layer of sound-absorbing material located between the two walls. This aerodynamic approach "traps" the noise from the airflow before it exits the outlet, drastically reducing the noise level compared to conventional duct ventilators. This technology allows for the maintenance of high air flow without the accompanying "hum" of typical systems.

The electrical connection box of the TD-Silent can be fully rotated 360 degrees around the body of the ventilator. This offers unparalleled flexibility during installation, as the technician can orient the cable entry in any direction, regardless of the position of the unit. It is especially useful in tight spaces or limited false ceilings where access for wiring is difficult.

• Ventilation for residences (bathrooms, kitchens, rooms).
• Commercial spaces and offices.
• Ventilation systems with heat recovery.
• Spaces with low noise level requirements.

For optimal utilization of silent operation, it is recommended to use flexible air ducts and avoid sharp angles in the connections, in order to reduce air resistance and flow noise.
