About the Airtac BSL General Purpose Silencer BSL02
The BSL02 screws onto a 1/4in PT valve exhaust port and breaks up the pressure pulse that leaves the port as a sharp crack each time the valve dumps. Air passes through a brass-particle sintered sound-absorbing cover on an aluminium-alloy body, cutting exhaust noise by 13 dB at 0.5 MPa. AirTAC also rates this part for negative pressure down to -750 mmHg (10 Torr), so it can be used on vented vacuum circuits as well as standard 0-1.0 MPa air lines.
Sintered brass is the tough option in the AirTAC silencer line. The element tolerates knocks from passing trolleys, hot valve bodies and oily exhaust air that would age a resin filter faster. Note that AirTAC publishes only dimensions and ratings for the standard BSL range - there is no weight figure for this SKU - so select by port size and valve rather than by mass.

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 BSL02 Is Used
Bottling line valve islands
On a filling hall's 1/4in-port valve bank, operators stand beside the manifold for a full shift, and every cylinder dump adds to the din. A BSL02 on each exhaust port drops that crack by 13 dB at 0.5 MPa.
Stamping press retrofits
Bringing a press cell under a workplace noise limit usually starts at the exhausts. The sintered brass element survives the hot, oily air near a stamping press where a resin muffler would age quickly.
Vacuum pick-and-place cells
Carton erectors and pick-and-place heads vent ejector exhaust straight into the operator area. With a -750 mmHg (10 Torr) negative-pressure rating, the BSL02 handles those vacuum dump ports without re-rating concerns.
Is the Airtac BSL General Purpose Silencer BSL02 the Right Part?
Pick metal when the silencer will be knocked, run hot or see dirty exhaust; pick a resin PAL when lowest noise matters more than ruggedness, because PAL earns 25 dB against this BSL's 13 dB, both measured at 0.5 MPa. Step down to BSL01 for a 1/8in port or up to BSL03 for 3/8in: the smaller part costs less but restricts a large valve's exhaust and drags out the return stroke. AirTAC also lists BSL in M5 and 1/2in, and a BESL throttling version if you want exhaust-speed adjustment built into the same part. Size to the valve's exhaust port, never down.
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 BSL02 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature range of -20 to +70 C. The connection is a 1/4in PT thread, and the sintered brass sound-absorbing cover delivers 13 dB of noise reduction at 0.5 MPa.
No. AirTAC publishes flow for these silencers as a characteristic curve only, and an undersized or clogged element restricts exhaust, slowing the cylinder's return stroke. Match the BSL02 to a 1/4in exhaust port; step up to BSL03 or BSL04 for larger ports. A little thread sealant on the PT thread helps sealing, but keep it away from the sintered face so it does not block the pores.
