Product Description

Vacuum System Silencer PSU 3/8 – Lightweight Plastic Muffler

PLASTIC SILENCER PSU 3/8 Additional image 1

DALON’s PSU 3/8 Plastic Vacuum Silencer is a compact, high-performance pneumatic exhaust muffler engineered for vacuum and low-pressure air systems. Featuring a 3/8” NPT male thread, this silencer offers quick integration with valves, actuators, vacuum pumps, and controllers across industrial and laboratory environments.

 

Made from flame-retardant polyethersulfone (PSU), the silencer ensures excellent thermal and chemical resistance. It is well-suited for use in sensitive or space-limited installations where quiet, reliable air exhaust is essential. The sintered structure within helps disperse the flow of exhaust air while effectively minimizing noise and turbulence.

 

DALON’s PSU silencers are lightweight, corrosion-resistant, and designed for long-term reuse, making them ideal for systems requiring cleanroom compatibility, precision airflow, or frequent start-stop cycles.

FAQ – Frequently Asked Questions

 

 

Q1: What does a vacuum silencer do?

It reduces the noise and vibration generated by exhaust air in vacuum systems, protecting components and improving user safety.

 

Q2: Is this silencer reusable?

Yes. The PSU material is washable and supports multiple cycles of reuse without losing performance.

 

Q3: Can it be used in high-humidity environments?

Absolutely. The PSU body is moisture- and corrosion-resistant, making it suitable for humid or demanding environments.

 

Q4: Is this compatible with any 3/8” pneumatic device?

Yes. It uses a standard 3/8” NPT thread, which fits most vacuum valves, actuators, and connectors.

 

Q5: What’s the typical lead time for delivery?

For standard models, production is usually completed within 30 days. Customized versions (including molds) take 35–40 days.

 


 

 

What Do People Also Ask (Answered)

 

 

Q: Can a plastic silencer reduce vacuum pump noise effectively?

Yes. DALON’s PSU silencers are designed to absorb sound energy while maintaining airflow, significantly reducing pump or ejector noise.

 

Q: Is it safe to use plastic silencers near electronics?

Yes. PSU is a non-conductive, chemically inert material and is widely used in electronics and automation systems.

 

Q: Can I order a customized version for my OEM design?

Definitely. We offer full customization based on size, thread, shape, or color. Contact DALON for detailed options.
