1 IN-LIN MIXD LOW DUT NS ULTR-QUIT Series NW Low profile Mixed-flow fans with sound-absorbent insulation. xtremely quiet. Manufactured in plastic material, with a specifically designed internal skin to direct the sound waves in the right angle for them to be captured by the sound-absorbent material (1). itted with rubber gaskets on the inlet and outlet to absorb vibrations, a body that can be dismantled. onnection box can be rotated 3º, to facilitate easy connection of the power cable. Motors Speed controlable 2 V Hz motor, of two speed motors. Motors are IP44, class, with ball bearings and safety thermal overload protection. (1) xcept the TD-1 SILNT, that is fitted with the special floating motor system patented by S&P. Shhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh range, the quietest fans in the world in their class

2 Low profile Low noise level The low profi le of the fans makes them the most effective solution for installations where the space of installation is limited such as false ceilings. asy maintenance onnection box rotated 3º Sound waves produced inside the TD, are directed through the perforated inner skin and absorbed by the layer of sound-absorbent material. lexible washers Support bracket i-material support brackets, which in addition to simplifying installation, serve as joint seals. onnection box can be rotated 3º, to facilitate easy connection of the power cable. i-material inlet and outlet incorporating a fl exible washer to facilitate installation and absorb vibrations. Support bracket for installing on a wall or ceiling, incorporating twin-material support brackets for the motor section that absorbs vibration. asy to mount Loosen and open clamps on both sides Remove the fan body Remove the terminal box lid onnect electrical supply Remount the fan body by tightening the clamps 531

Practical examples of installing TD SILNT range D D D TD Silent range offers one of the most versatile fansystems on the market today. Due to its fl exibility it can be used in a multitude of small or medium fan installations. specially in places where working people and the ventilation system works for many hours, in these cases the sound level becomes an essential element for comfort.
