About the Airtac PALM Mini Plastic Silencer PALM02D
Every stroke of a directional valve fires a pulse of compressed air out of its exhaust port, and that pulse is what your ears register as the crack of escaping air. The PALM02D screws into a 1/4in PT exhaust port and breaks that pulse up through a polyethylene-fibre element, cutting exhaust noise by 25 dB at 0.5 MPa - the deeper of the two reduction figures AirTAC publishes for this range.
PALM is the compact version of the PAL plastic silencer: a POM top cover and body with the same 25 dB resin element in a shorter body. The D suffix on this SKU means the top cover and body are moulded in black instead of natural resin, so it stays visually unobtrusive on visible pipework or colour-coded machine sections. At code 02 it takes a 1/4in PT thread and is the largest size PALM is made in.

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 PALM02D Is Used
Benchtop laboratory analyser
Sample-handling cylinders on lab instruments cycle constantly a metre from the operator's ear; the black PALM02D hides against dark enclosures and its 25 dB resin element keeps instrument noise down in a quiet room.
Valve bank on a carton packing machine
Solenoid valves with 1/4in exhaust ports on a packaging line fire dozens of times a minute beside operators; a PALM02D on each port tames the crack without adding metal weight to the manifold.
Workshop brought under a noise limit
When a plant must meet a workplace noise threshold, replacing bare 1/4in exhausts with 25 dB PALM02D silencers is one of the cheapest single-line changes an engineer can make before resorting to enclosures.
Is the Airtac PALM Mini Plastic Silencer PALM02D the Right Part?
Choose resin when noise reduction matters most and the part will not be battered or run hot: PALM delivers 25 dB against the 13 dB of the sintered-brass BSL and BSLM metal series, which you should pick instead where the silencer gets knocked, lives near sparks, or sees abrasive dirty exhaust. If you want to throttle exhaust speed as well as silence it, step up conceptually to the BESL throttling series, though that is a metal part.
Size to the valve exhaust port, not down - an undersized silencer throttles the exhaust and drags out the return stroke. Within PALM itself the only neighbour is one size down, PALM01 on a 1/8in thread; there is no PALM above 1/4in, so if your port is 3/8in or 1/2in you need the full-size PAL series instead, which runs 01 through 04. Fit the 1/4in thread with a turn or two of seal tape on the male port.
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 PALM02D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a working temperature of -20 to +70 C. This SKU has a 1/4in PT thread (code 02) and is the largest of the two sizes PALM offers, the other being PALM01 on a 1/8in thread. Exhaust noise reduction is 25 dB at 0.5 MPa.
No. The D suffix specifies a black top cover and body instead of the natural resin finish; the POM material, the polyethylene-fibre element, the 1/4in thread and the 25 dB performance are identical to the standard PALM02. It is purely a cosmetic option for machines where a dark fitting looks better or matches the panel colour scheme.
