About the Airtac PALM Mini Plastic Silencer PALM02
The PALM02 is the 1/4in PT member of AirTAC's mini plastic silencer family. It screws onto a valve or cylinder exhaust port and breaks up the pressure pulse that would otherwise leave as a sharp crack, cutting noise by 25 dB at 0.5 MPa - the highest reduction figure published anywhere in this silencer range. The element that does the work is a polyethylene fibre filter inside a POM top cover and body, so the whole part is light resin rather than metal.
PALM is the compact take on the PAL series and exists in exactly two threads: 1/8in (PALM01) and 1/4in (this model). AirTAC offers a D suffix on PALM that changes the top cover and body to black, useful when natural or grey plastic clashes with a machine's panel colour. Being POM, the body will not rust in damp or wash-prone areas, but keep it clear of hot swarf and heavy knocks that a metal body would shrug off.

Choosing a Silencer
- check Sintered-brass types (BSL / BSLM / BESL) give 13 dB and take rough treatment.
- check Resin types (PAL / PALM / PPA) give 25 dB and weigh far less.
- check PPA plugs straight into a tube instead of a thread, and is copper-free for sensitive processes.
- check BESL adds an adjustable throttle, so it silences AND sets exhaust speed in one part.
- check An undersized or clogged silencer shows up as a slow return stroke - size it to the valve's exhaust port.
Where the Airtac PALM Mini Plastic Silencer PALM02 Is Used
Valve bank on a biscuit-packing line
Operators stand beside a 1/4in-ported solenoid bank for a full shift, and every cycle adds to the hiss. A PALM02 on each exhaust port takes 25 dB off that noise without adding metal weight to the manifold.
Laboratory sample handler
Small pneumatic actuators venting inside a bench-top analyser are close to the operator's ears. The 1/4in thread fits the compact valves usually specified there, and the all-resin body adds nothing magnetic or corrosive to the enclosure.
Noise-limit retrofit on an assembly air bench
When a workstation has to meet a workplace noise limit, exhausted quick-exhaust valves are often the culprit. Swapping open 1/4in ports for PALM02 silencers is the cheapest single step, and the D suffix black version keeps the retrofit visually invisible.
Is the Airtac PALM Mini Plastic Silencer PALM02 the Right Part?
Step down to PALM01 if the exhaust port is 1/8in; PALM stops at 1/4in, so for a 3/8in or 1/2in port in resin you move to the full-size PAL03 or PAL04. The trade-off across the whole range stays the same: sintered-brass BSL types manage 13 dB but tolerate knocks, heat and dirty air, while this resin build delivers 25 dB where that extra 12 dB is what pulls a cell under its noise target. Size to the valve's exhaust port rather than a size down - an undersized or clogged silencer throttles the exhaust and drags out the return stroke.
Quick checklist
- ✓ Tube outside diameter matches exactly
- ✓ Thread size and standard match the port
- ✓ Working pressure within 0 - 1.0 MPa (0 - 10 kgf/cm2)
- ✓ Temperature within -20 to +70 °C
- ✓ Noise target: 13 dB metal or 25 dB resin
Airtac PALM Mini Plastic Silencer PALM02 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa and operating temperature -20 to +70 C. The thread is 1/4in PT and the silencing effect is 25 dB at 0.5 MPa, the figure shared by the entire resin PAL family.
No. PALM is made only in 1/8in (PALM01) and 1/4in threads, so fitting it through a reducing bush would throttle the exhaust and defeat the purpose. Order PAL03 for a 3/8in port instead - the same POM and polyethylene fibre construction and the same 25 dB reduction, just in a full-size body.
