Ventilation silencer / fan / metal

The ISA,YSA & DSA series attenuators are intended to avoid the noise produced by the moving parts such as fans into the locations above the levels allowable by codes and standards. They are particularly useful in areas where there is a need to attenuate surplus noise power.
These attenuators are developed in 2 main styles namely as with rectangular cross - section and with circular cross - section. The attenuators with rectangular cross - sections are developed having baffles either 100mm dense or 200mm thickness.
The spacing of baffles range from 40mm to 100mm - for the 100mm thick baffles; and 80mm to 200mm . Also available to these sound attenuators marked ISA100 and ISA200, there are also attenuators with circular cross - sections that are known as YSA and DSA.
The YSA models are developed from 80mm up to 400mm and they have attenuation material on the interior surfaces of the exterior walls. The DSA variants have an add on circular insert to improve the effectiveness.
