Silencers & Bug ScreensProtection from debris ingress that could cause the valves to wear prematurely or become unreliable is of the utmost importance for pneumatic valve systems. This protection, by means of bug screens of wire mesh or gauze is placed on valve exhaust ports and offers a very effective means of protecting. Loud exhaust discharges in pneumatic systems can contravene safe noise limits. By extending the flow path through the filter, our silencers offer the port protection of bug screens and reduce noise by 70%. Our Bugs screens and exhaust silencers are ATEX and GOST Ex certificated as standard.
