PLASTIC SILENCER PSU 1/4

DALON’s PSU 1/4 Plastic Silencer Muffler is a compact, flame-resistant air exhaust muffler designed to reduce noise and discharge pressure in pneumatic systems. Constructed from polyethersulfone (PSU)—a high-performance thermoplastic—this silencer offers superior durability, heat resistance, and chemical stability, even in aggressive or high-demand industrial environments.

The 1/4” NPT male thread ensures compatibility with most solenoid valves, air cylinders, and pressure regulators used in automation, control panels, and laboratory setups. Its streamlined design minimizes space usage while delivering efficient sound attenuation and maintaining airflow balance with minimal backpressure.

Whether you operate cleanroom equipment, medical devices, or factory machinery, the PSU 1/4 silencer provides long-term performance, reduced maintenance, and easy installation. Its washable structure supports reuse, cutting down on replacement costs and system downtime.
