RSA

The RSA range of silencers has been designed to provide robust and efficient noise absorption in air conditioning and ventilation ducts. Available in different sizes, they are designed for use together with axial fans of the AXC range.  The size of the silencer determines the thickness of the galvanised steel casing. The silencer is supplied with a flange according to Eurovent 1/2. The mounting flange has a threaded insert. For effective noise suppression, the RSA silencer should be mounted directly before or after the fan. 

The acoustic material fitted in the RSA silencer is mineral wool which also has protection against erosion for continued effectiveness. The acoustic data has been tested in accordance with ISO 7235. Stainless steel execution of the RSA silencer range is available upon request.
