S&A Industries manufactured a porous, air-intake system (AIS), noise-reduction duct that meets automotive environmental and engine compartment requirements. The non-woven, compression-molded, recyclable polyester used in the duct reduces engine noise. Permeability can be adjusted to change its acoustic performance and it offers excellent temperature resistance. The porous part also weighed less than a molded plastic part and featured a water drain valve and is hydrophobic treated.

The duct was created using highly specialized software, such as LAMPS/SAPY for noise, SCRYU/Fluent for pressure drop and NX Unigraphics for design. We diligently tested and validated the parts and offered global delivery. For more information, please contact us directly.
