About the Airtac PAL Plastic Silencer PAL03
When a directional valve vents, the air leaving its exhaust port is a compressed pulse, and that pulse is heard as the sharp crack that dominates a pneumatic machine's sound. The PAL03 threads onto a 3/8in PT exhaust port and lets that pulse expand through a polyethylene-fibre element, cutting exhaust noise by 25 dB measured at 0.5 MPa - the largest reduction figure in the AirTAC silencer range.
Both the top cover and the body are injection-moulded from POM, so the part adds almost nothing to a manifold's mass and cannot rust in humid plant air. AirTAC also lists a D-suffix version of the PAL series moulded entirely in black, which matters on machines where the valve bank and its silencers sit in plain view of the operator.

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 PAL03 Is Used
Beverage bottling valve bank
Packaging halls run rows of valves a metre from where operators stand for a full shift. Fitting PAL03 to each 3/8in exhaust port removes the repeated crack of each cycle and is one of the cheapest ways to pull a workstation under a workplace noise limit.
Laboratory vacuum circuit
The PAL series is rated for negative pressure down to -750 mmHg (10 Torr), so a lab bench ejector or vacuum-holding fixture can vent through this same 3/8in silencer instead of hissing into the room.
Print-and-cut conveyor stoppers
Stopper and pusher cylinders on web-handling conveyors fire several times a minute right beside the operator station. A resin silencer keeps the exhaust note down without adding the weight that a brass body would hang on the manifold.
Is the Airtac PAL Plastic Silencer PAL03 the Right Part?
This 3/8in size sits between PAL02 (1/4in) below it and PAL04 (1/2in) above it; the compact PALM family stops at 1/4in, so PAL03 is already past the point where the mini body is offered. Match the thread to the valve's exhaust port rather than stepping down for tidiness - a choked silencer holds backpressure in the valve and visibly slows the cylinder's return stroke. Where the part will take knocks from carts or sit near hot, oily metal, the sintered-brass BSL03 survives better but reduces noise by only 13 dB; choose PAL03 when noise is the priority and the element will not be abused.
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 PAL03 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), usable in vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a service temperature range of -20 to +70 C. This SKU carries a 3/8in PT male thread, and every size in the PAL series shares the same 25 dB noise reduction measured at 0.5 MPa.
Mechanically it is identical. The D suffix only selects AirTAC's black top cover and body instead of the natural POM finish; the polyethylene-fibre element, the 3/8in thread and every rating stay the same. Specify D purely where the silencer is visible on the machine front and a dark component looks better.
