Features
The Deflector GF exhaust acoustic silencer is designed to reduce fan noise from outdoor units such as chillers, rooftop systems, and refrigeration units. Its 45° curved geometry allows acoustic flow to be directed toward a specific area, helping protect sensitive or occupied areas. Thanks to Slim Hurdle™ technology and 20 mm thin sound-absorbing baffles, Deflector GF offers a minimum net open area of 90% and a pressure drop of less than 15 Pa, ensuring full compatibility with low-pressure fans.
For complete acoustic treatment along ventilation ducts, Deflector GF can be supplemented with SH™ baffle silencers, which are ideal for reducing noise propagation within ductwork.
