About the Airtac PALM Mini Plastic Silencer PALM01
Every time a valve dumps its air, the escaping pulse cracks like a gunshot. The PALM01 screws onto a 1/8in PT exhaust port and pushes that pulse through a polyethylene-fibre element, cutting noise by 25 dB at 0.5 MPa. The housing and top cover are moulded POM, so the whole part weighs almost nothing and will not rust or shed metal near sensitive work.
PALM01 is the smaller of the only two sizes the PALM range offers - 1/8in and 1/4in PT, nothing else. That compact footprint is the point: it fits exhaust ports that a full-size PAL would crowd, such as closely spaced valve stations or small cylinders. A -D ordering suffix gives the same part with a black cover and body where the natural look is not wanted.

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 PALM01 Is Used
Laboratory test rigs
On a lab bench where a small cylinder cycles beside the operator's ear, the PALM01's 25 dB resin element keeps the 1/8in exhaust port from cracking every stroke, and the all-POM body leaves nothing conductive near the instruments.
Compact PCB pick-and-place heads
Mini cylinders on electronics assembly heads exhaust through tightly spaced ports. The PALM01's short POM body fits where larger silencers would foul the neighbouring valve, while staying copper-free around the boards.
Bench-top counting and filling stations
Small reject and indexing cylinders on a counting station sit right under the operator's ear all shift. Fitting PALM01 on each 1/8in exhaust port brings the repeated crack of venting air down 25 dB at 0.5 MPa.
Is the Airtac PALM Mini Plastic Silencer PALM01 the Right Part?
Choose resin when noise is the priority and the part will not be bashed by trolleys or run in hot, oily air. PALM drops 25 dB against the 13 dB of the sintered-brass BSLM, so on a bench or inside a machine frame the resin element is noticeably quieter, at the cost of lower mechanical and heat tolerance. If the port takes abuse, step across to BSLM01 instead.
PALM01 is already the smallest PALM size, so there is nothing below it - the only step up is PALM02 at 1/4in PT, which suits a larger exhaust port and passes more air on the return stroke. Never size down to make the silencer fit: an undersized or clogged element throttles the exhaust and drags the cylinder's return stroke. If 1/8in is right but the PALM body is too small for the flow, the full-length PAL01 on the same thread is the next option. Note the PALM range has no M5 and no 3/8in or 1/2in sizes at all.
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 PALM01 FAQ
The PALM01 is a mini plastic silencer with a PT 1/8in (01) thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it tolerates negative pressure to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. The housing and cover are POM with a polyethylene-fibre element, giving a 25 dB noise reduction at 0.5 MPa.
Size to the valve's exhaust port, not down and not up. PALM comes only in 1/8in and 1/4in PT, so if your port is 1/8in this is the right part, and stepping to PALM02 via an adaptor adds dead volume without helping anything. If the return stroke of your cylinder feels slow with the PALM01 fitted, the element is doing its job but the port itself may be the restriction - move to the full-size PAL01 on the same 1/8in thread, whose larger body passes more exhaust air.
