Airtac BSL General Purpose Silencer BSL01
The AirTAC Airtac BSL General Purpose Silencer BSL01 is a genuine universal silencer that cuts exhaust noise by 13 dB at 0.5 MPa using a sintered brass sound-absorbing cover in an aluminium-alloy body.

About the Airtac BSL General Purpose Silencer BSL01
Every time a directional valve shifts, the air trapped on the other side dumps through the exhaust port in one sharp pulse. That pulse is the crack your operators hear all shift. A silencer screws onto the exhaust port and forces the air through a porous element, spreading the pulse out until it becomes a soft hiss instead of a bang.
The BSL01 is the 1/8 inch PT member of AirTAC's BSL universal silencer family. The body is aluminium alloy and the sound-absorbing element is a brass-particle sintered cover, which reduces exhaust noise by 13 dB at 0.5 MPa. Sintered brass is the reason to pick this series over resin: it shrugs off knocks from passing trolleys, tolerates warm compressor air and keeps working in oily shop air where a plastic element would age quickly. The 1/8 thread is a standard PT taper, so a wrap of PTFE tape seals it into any matching exhaust or muffler port.

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 BSL General Purpose Silencer BSL01 Is Used
Carton packing line valve bank
On a case-packer or shrink-wrap line the valve bank sits at hip height beside the operators, and every cylinder stroke vents a burst of air at ear level. A BSL01 on each 1/8 exhaust port drops the crack to a hiss without adding any throttle to slow the machine cycle.
Metalworking cell with exposed pneumatics
In a machining or fabrication cell where swarf, coolant mist and the occasional knocked-over tool tray are facts of life, the sintered brass element on the BSL01 survives contact that would crack a resin silencer body.
Meeting a workplace noise limit
If an audit has flagged a machine's exhaust noise against an 85 dB exposure limit, fitting BSL01 silencers to every 1/8 exhaust port is a low-cost first step before redesigning the whole valve layout.
Is the Airtac BSL General Purpose Silencer BSL01 the Right Part?
At 13 dB the BSL family is the tough choice; if the silencer lives in a quiet room where every decibel counts and nothing will hit it, the resin PAL series at the same thread size buys 25 dB instead. If you also want to throttle the exhaust speed while you silence it, step up to the BESL throttling silencer, which starts at 1/8 thread and adds an adjustable exhaust valve to the sintered element.
Within BSL the BSL01 sits one step above the smallest. Step down to the M5 thread if the valve port is a small metric fitting; step up to the BSL02 for a 1/4 inch port. Sizing matters more than it looks: match the silencer to the valve's exhaust port rather than fitting a smaller part for tidiness, because an undersized or clogging element restricts exhaust flow and visibly slows the cylinder's 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 BSL General Purpose Silencer BSL01 FAQ
The BSL01 has a 1/8 inch PT (taper) thread and a brass-particle sintered element rated at 13 dB noise reduction at 0.5 MPa. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it tolerates negative pressure down to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the operating temperature range is -20 to +70 C. The same rating set applies across the whole BSL family.
Not recommended. The silencer should match the valve's exhaust port size, and stepping down restricts the exhaust path. A restricted exhaust slows the air leaving the cylinder, which lengthens the return stroke and can change the cycle time of the machine. If the port is smaller than 1/8 inch, use the BSL in the M5 thread instead; if the port is larger, use the BSL02 in 1/4 inch. Note also that the BSL01's -750 mmHg vacuum rating means it can stay on ports that see vacuum, such as circuits venting through ejectors.
