Brass silencer filter for pneumatic vacuum systems. Male thread 10 and 15 mm. Options of 15 and 25 mm in length.
The brass silencer filter is an essential mechanical component for pneumatic and vacuum systems: it reduces the noise produced by the release of compressed air and filters particles that could damage the pump or contaminate the process. Made from brass, it offers corrosion resistance, robustness against high pressures and a long service life. It is the part that correctly closes and protects workshop vacuum installations.

What it is used for
This filter is installed on the air outlet of vacuum pumps and pneumatic systems to dampen sound and retain impurities. It is especially useful in moulding, composites and special effects workshops where vacuum chambers are used to degas silicones and resins.
- Silencing air discharge on workshop vacuum pumps
- Filtering particles in pneumatic and hydraulic systems
- Protecting the vacuum pump from particle contamination
- Reducing ambient noise during the silicone and resin degassing process
- Complementing Feroca's standard and professional vacuum systems
- General workshop pneumatic installations requiring an exhaust silencer
How to use it
- Identify the air exhaust outlet on your vacuum pump or pneumatic system.
- Select the correct option based on the thread diameter of your equipment: 10 mm male thread (standard system) or 15 mm (professional system).
- Hand-thread the filter into the exhaust outlet, making sure the thread fits cleanly without forcing.
- Tighten with a spanner using the filter's hex until firm, without exceeding the tightening torque to avoid damaging the brass thread.
- Start the system and check there are no air leaks at the joint and that the noise level has decreased noticeably.
- Inspect the filter periodically: if discharge pressure increases or flow rate drops, the filter element may be saturated and should be replaced.
Usage tips
Choose the right size
Before ordering, check the thread diameter of your pump's outlet. A 10 mm thread fits the standard vacuum system; the 15 mm fits higher-flow or continuous professional-use equipment. Installing a filter of the wrong size can cause excessive back pressure or leaks.
Preventive maintenance
The internal filter element can become clogged over time, especially if the workshop environment contains plaster dust, fibreglass or other particulate materials. Inspect it every so many hours of use: a clogged filter raises the pump's working temperature and reduces its service life. Keeping a spare filter in stock is good workshop practice.
Integration with your vacuum system
If you use a vacuum chamber to degas platinum silicones or polyurethane resins, this silencer filter is the last line of protection before air escapes to the environment. A well-sealed and silenced system improves working conditions and extends the pump's life. Make sure all circuit connections (hoses, fittings and this filter) are in good condition to maintain the required vacuum level.
Frequently asked questions
What does a silencer filter do on a vacuum pump?
It serves two simultaneous functions: it dampens the noise generated by compressed air discharge and retains particles that could contaminate the environment or damage system components. In workshops where silicones and resins are degassed, it considerably reduces the noise level during work.
How do I know which filter size I need?
It depends on the outlet thread of your pump or pneumatic system. The filter with a 10 mm male thread and 15 mm length fits Feroca's standard vacuum systems; the one with a 15 mm male thread and 25 mm length corresponds to higher-flow professional systems. If in doubt, consult your equipment manual or contact Feroca.
How often should the filter be replaced?
There is no fixed interval: it depends on use and the workshop environment. A clear sign that the filter is saturated is a drop in flow rate or an increase in the pump's working temperature. In dusty workshops (plaster, fibre, resin) it is worth inspecting every few weeks. Having a spare unit avoids unexpected downtime.
Can I use this filter in a compressed air circuit as well as vacuum?
Yes. The brass silencer filter is suitable for both vacuum systems and exhaust outlets in compressed air pneumatic circuits, always within the usual workshop pressure and temperature ranges. Brass handles the working conditions of both types of installation well.
Is it necessary to use PTFE tape or sealant on the thread?
In most pneumatic installations it is recommended to apply PTFE (Teflon) tape to the male thread to ensure a tight seal and facilitate future removal. Tightening should be firm but without overdoing it to avoid damaging the brass thread or the thread on the receiving equipment.
Is this filter compatible with degassing systems for silicones and resins?
Yes. It is the component installed on the exhaust outlet of the pumps included in Feroca's vacuum systems, both standard and professional. It allows working with less noise while degassing platinum silicones, polyurethane resins or other moulding materials.
Does brass resist solvent or resin vapours?
Brass is a material with good general chemical resistance and handles the vapours commonly found in workshops (polyurethane resins, silicones, Release agents) well. It is not recommended for direct and prolonged contact with strong acids or concentrated ammonia, but in the exhaust position of a workshop vacuum pump it presents no issues.
