About the Airtac PAL Plastic Silencer PAL02D
The PAL02D is a resin exhaust silencer that screws onto a 1/4in PT exhaust port and breaks up the pressure pulse that makes the sharp crack of venting air. Its polyethylene-fibre element cuts noise by 25 dB at 0.5 MPa, the deepest reduction AirTAC publishes for any silencer family in this kit. The D suffix means the top cover and body are moulded in black POM instead of the standard natural colour, so the part disappears visually against dark machine frames.
Every load-bearing surface is POM, a rigid acetal resin that shrugs off knocks better than most plastics while staying far lighter than a sintered-brass body. AirTAC offers the PAL series in 1/8in, 1/4in, 3/8in and 1/2in PT only - there is no M5 entry in this range - and the 02 thread sits right at the point where the compact PALM mini range ends, so 1/4in is the largest size where you can still swap in a mini body if panel space is tight.

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 PAL Plastic Silencer PAL02D Is Used
Packing line valve banks
On a carton sealer or shrink-wrapper where operators stand beside the valve manifold for a full shift, the 25 dB resin element turns the end-of-cycle exhaust crack into a soft hiss at head height.
Laboratory sample handlers
In a lab autosampler or diagnostic analyser with small pneumatic actuators cycling all day, the black POM body stays visually quiet on the instrument panel while cutting exhaust noise to library levels.
Meeting a workplace noise limit
When a shop floor is being brought under a workplace noise assessment, swapping bare 1/4in exhaust ports on assembly-station valves for PAL02D units removes the sharpest repeated noise peaks at no control-wiring cost.
Is the Airtac PAL Plastic Silencer PAL02D the Right Part?
Choose resin when the port is exposed to people rather than to chips, sparks or hot wash-down, because the fibre element gives 25 dB against the 13 dB of the sintered-brass BSL and BSLM. If the silencer will be struck by trolleys or sit near a heat source, step sideways to BSL02 instead. If the valve exhaust is 1/8in, PAL01 is the size below; if it is 3/8in, PAL03 is the next step up, and from 3/8in upward the mini series no longer exists so PAL and BSL are your only options.
Always match the silencer thread to the valve's exhaust port rather than sizing down to keep the part small. An undersized element restricts exhaust flow, slows the cylinder's return stroke and can shorten valve life - the bore of the silencer must equal or exceed the port it fits.
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 PAL Plastic Silencer PAL02D FAQ
Working pressure is 0-1.0 MPa (0-10 kgf/cm2) with a negative-pressure capability of -750 mmHg (10 Torr). Proof pressure is 1.5 MPa. Service temperature range is -20 to +70 C. This model carries a 1/4in PT male thread, and like the whole PAL family it achieves a 25 dB noise reduction at 0.5 MPa through its polyethylene-fibre element.
No. The D suffix only changes the colour of the POM top cover and body to black; the thread, the fibre element, the 25 dB figure and every pressure and temperature rating are identical to the standard PAL02. Pick it when you want the silencer to blend into a dark machine frame rather than stand out in safety yellow or natural resin.
