Absorptive Silencers

NK A silencers are absorption type. The gas passes through a pipe with inner core covered with high-performance sound-absorbing material protected by perforated metal acoustic. The nominal diameter of entry defines the designation of the silencer. The inlet and outlet tubes are axial, the steel body is a cylindrical shape or square as we requested, and are closed by flat bottoms or pumped.


All internal and external parts of the silencer are treated with primer high temperature. These include: mating flange gaskets and hardware, support-off sparks. For special equipment for large diameters and temperatures above 500 ° C, contact us.
