Powersprint Pierced Stainless Steel Absorber Tube

The Powersprint pierced stainless steel absorption tube is designed for the manufacture or repair of an absorption muffler. It serves as the inner conduit of the muffler and is used with acoustic insulation suitable for exhaust systems.

Exhaust gases flow through the tube, while the sipes allow sound waves to reach the absorbent material surrounding it. Noise attenuation depends on the silencer as a whole, particularly its sizes and the trim used.

Available in AISI 304 or AISI 409 stainless steel, with lengths of 500 or 1,000 mm depending on the model, this tube allows the silencer design to be adapted to the mounting sizes. Its two non-pierced ends facilitate integration and assembly.

Choose the material, length, and diameter that best suit your project from the available options. When refurbishing an existing silencer, verify the sizes of the inner duct and the available space for the acoustic trim.
