Circular silencer - with a core

Round silencers or circular silencers are built from noise absorbing materials that reduce noise in round tube systems without significant pressure loss.

There are two types of circular silencers. With and without core. The addition of a core in the center of the silencer adds significant improvements in noise level reduction.

HNA silencers were tested at 4000C for two hours and found durable.

Silencers intended to run alongside bellows will be supplied with forge nuts to match custom deep flange holes in the blower.
