The noise silencers form one of essential components in implementation of any noise control measures. They characterized in precise processing, heavy duty structure, and highly favourable attenuation factor.
lengths up to 4,000mm, diameters 220mm up to 2,000mm, vertical or horizontal
simple through, resonance, or combined design Cladding
made from black steel, absorption filling comprises non-flammable sound absorbing material being separated from the waste gas flow by a perforated metal sheet and non-flammable fabric.
On the basis of the calculation of the required noise attenuation, the necessary protective noise control measures are designed, which then become crucial in the working design of the air-conditioning (HVAC).
