PSU 1/2 plastic silencer is a compact and effective solution for suppressing exhaust noise in compressed air and pneumatic systems. Designed with durable, lightweight polymer, this silencer is ideal for valves, cylinders, air tools, and other components where space-saving and cost-efficient noise control is essential.
With its 1/2" threaded base, it installs easily into most pneumatic exhaust ports and provides low backpressure, preserving system efficiency while significantly reducing discharge noise.

FAQ – Frequently Asked Questions
Q1: What is the PSU 1/2 silencer used for?
It reduces noise and diffuses airflow at the exhaust port of pneumatic components, such as valves and cylinders.
Q2: Is it suitable for lubricated air systems?
Yes. It works with both dry and lightly oiled compressed air, though filtration may vary by application.
Q3: Can I reuse this silencer after cleaning?
In most cases, yes—blow through with compressed air to remove dust. Replace if performance degrades.
Q4: Does it affect system airflow or pressure?
Minimal pressure drop. Designed to provide balanced noise suppression and flow control.
Q5: Is it flame resistant?
Standard PSU models are not flame retardant, but flame-resistant versions (e.g., SPL-F series) are available on request.
Q6: Can DALON provide custom silencer sizes?
Absolutely. We support OEM customization for shape, color, thread, and filtration structure.
