Pressure-control silencer

exhaustfor compressed airfor machinery

Overview
ES series expansion silencers are engineered to reduce noise when compressed air is expanded or depressurised to ambient pressure. They are intended for industrial pneumatic exhaust points where controlled expansion and sound attenuation are required.

Variants

• ES B series — exhaust silencers with an optional spring-loaded bypass valve mounted opposite the inlet port; the valve opens when internal pressure exceeds the specified limit to protect the silencer from overload.
• ES E and ES BE series — versions supplied with nipple connection (nipple-style outlet) for specific piping or downstream fittings.

Technical data
No detailed technical table is provided on the page. Materials, dimensions and performance values depend on the selected ES model and should be confirmed with the product datasheet or supplier.

Applications

• Pneumatic system exhausts in industrial machinery and production lines.
• Compressed-air blowdown or depressurisation points where noise control to ambient is required.
• Processes where a bypass valve protects the silencer from overpressure events.

Installation and maintenance

• Install the silencer downstream of the expansion point, ensuring correct orientation of inlet and outlet ports.
• Provide access for inspection and replacement; check bypass valve operation periodically if fitted.
• Follow supplier recommendations for mounting, maximum allowable pressure and temperature limits.
