The flexible silencers are thermally and acoustically insulated and, thanks to their elasticity and flexibility, allow easy installation in circular air distribution systems. SONOULTRA silencers have high UV resistance and are resistant to selected chemicals. The inner hose is made of non-woven fabric, the outer sheath of laminated aluminium. The thermal insulation of the silencer is made of 25 or 50 mm thick fibreglass. The connection throats are made of galvanised sheet metal. The silencers are suitable for use in HVAC systems without special requirements.
They are primarily adapted to reduce noise in ducts. They are very suitable for use in residential or small commercial heat recovery units for fresh air discharge or exhaust air intake.
