Frequently Asked Questions
What is a pneumatic breather silencer?
A pneumatic breather silencer is fitted to an exhaust or vent port in a compressed-air system. It disperses the air being released from the system to reduce the sharp noise normally produced by rapidly exhausting compressed air.
What size connection does this silencer use?
The PSU-15 uses a 1/2″ BSP male thread and should be installed into a compatible 1/2″ BSP female port.
Is this an air filter?
Not in the normal sense. It is primarily an exhaust silencer or pneumatic muffler. Its breather construction can also help keep larger debris away from an exposed vent port, but it should not be used as a replacement for a compressed-air moisture or particulate filter.
Does it reduce compressor noise?
It reduces pneumatic exhaust noise, such as the hiss produced when a valve or cylinder vents compressed air. It will not significantly reduce mechanical noise from the compressor motor or pump itself.
Where should it be installed?
It is normally screwed into an exhaust or breather port on a compatible pneumatic valve, manifold, regulator or other compressed-air component.
Can it be installed on a pneumatic cylinder?
Potentially, but it would normally be installed on the exhaust side of the valve controlling the cylinder, rather than directly onto the cylinder’s working air inlet. The exact installation depends on the pneumatic circuit.
Does it affect airflow?
Any exhaust silencer creates some resistance to airflow. PSU-series silencers are designed to provide noise reduction while maintaining relatively low back pressure. However, a dirty or blocked silencer can cause excessive restriction and affect pneumatic equipment performance.
What happens if the silencer becomes blocked?
A blocked silencer can restrict exhaust airflow. This may cause pneumatic cylinders or valves to operate more slowly or incorrectly. Inspect the silencer periodically and replace it if it becomes heavily contaminated or damaged.
Can I remove it if my pneumatic equipment seems slow?
You can use removal as a diagnostic check only after completely depressurising the pneumatic system. If performance improves once a heavily clogged silencer is removed, the silencer may need cleaning or replacement.
Can it be used with water?
No. The PSU series is designed primarily for compressed air.
Can it be used as an intake filter?
It is intended primarily for pneumatic exhaust/breather applications. Use a dedicated compressor intake filter where proper intake-air filtration is required.
What pressure can it handle?
The exact pressure rating for the AirCraft/Adendorff ACOUPB012 is not currently published. Comparable PSU-series silencers are rated up to approximately 1.0 MPa / 10 BAR, but this figure should be regarded as reference information rather than an official ACOUPB012 specification until confirmed by the supplier.
How much noise does it reduce?
Comparable PSU-series silencers quote approximately 25–35 dB(A) noise reduction, depending on the pneumatic circuit and exhaust conditions. This figure has not been independently confirmed for ACOUPB012 specifically.
What temperature can it operate at?
A comparable PSU series specifies approximately 5°C to 60°C, with operation potentially extending down to -10°C where moisture cannot freeze. This should be regarded as reference information rather than an official ACOUPB012 specification until confirmed.
Does it require maintenance?
There are no moving parts, but the porous element should be inspected periodically. Dust, oil contamination and debris can eventually restrict airflow.
How do I install it?
Depressurise the pneumatic system completely. Confirm that the port has a compatible 1/2″ BSP female thread, then screw the silencer into the port without cross-threading or overtightening it. The AirCraft supplier specifically warns that the air system should be depressurised before installation or removal.
Should I use thread-seal tape?
A small amount of suitable pneumatic thread sealant may be appropriate depending on the port and fitting design, but care must be taken not to allow sealant or PTFE tape fragments to enter the pneumatic system.
Why would I install silencers on several valves?
Machines with multiple pneumatic exhaust ports can produce considerable combined noise. Fitting appropriately sized silencers to several exhaust outlets can reduce overall pneumatic exhaust noise.
