About the Airtac BSL General Purpose Silencer BSL01-S
Every time a directional valve dumps its air, the exhaust port fires a pressure pulse that the ear hears as a sharp crack. A silencer screwed into that port breaks the pulse up before it leaves the machine. The BSL01-S is the stainless-steel BSL universal silencer in the 1/8in (01) PT thread, and it cuts exhaust noise by 20 dB at 0.5 MPa using a copper-particle sintered sound-absorbing element carried in a SUS304 body.
What sets the BSL01-S apart from the standard BSL01 is that body material. The SUS304 housing stands up to wash-down, salt-laden air, plating-fume atmospheres and other corrosive conditions that would chew through an aluminium-alloy silencer, while the damping element and the pressure, vacuum, proof-pressure and temperature ratings stay exactly as the standard line. It fits any valve or cylinder port tapped 1/8in PT and back-seats onto a flat sealing face, so no thread tape or sealant is needed on the exhaust fitting.

POM release button and chuck, aluminium-alloy guide, stainless spring gasket, NBR O-ring; body brass or PBT depending on the part. Stainless (-S): SUS304 silencer body. The sound-absorbing element remains copper-particle sintered, so this variant is specified for corrosion resistance rather than as a wholly copper-free part. AirTAC publishes flow as a characteristic curve rather than a single figure, so no L/min value is listed.

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-S Is Used
Food-plant wash-down stations
On packaging and tray-sealing machines cleaned with caustic spray between shifts, a SUS304 body on the 1/8in valve exhaust survives the hose-down that corrodes an aluminium silencer.
Electroplating and chemical dosing skids
Acid and alkali fumes near plating lines and dosing cabinets rapidly pit aluminium parts; the stainless BSL01-S keeps silencing a 1/8in dump valve in that atmosphere.
Marine and dockside pneumatics
Salt air on hatch-cover actuators, deck winches and quay-side control panels eats standard silencers within months; the SUS304 housing resists the corrosion and holds the 20 dB cut.
Is the Airtac BSL General Purpose Silencer BSL01-S the Right Part?
The stainless BSL series gives 15 dB of attenuation on the M5 thread and 20 dB on 1/8in, 1/4in, 3/8in and 1/2in, so BSL01-S sits in the 20 dB group. Below it is the M5 BSLM5-S, which trades attenuation and flow capacity for the smallest possible body; above it is BSL02-S in 1/4in, which moves more exhaust air on bigger valve ports. Always match the silencer thread to the valve exhaust port itself rather than stepping down to a smaller part on an adapter - an undersized silencer restricts the dump and stretches the cylinder return stroke.
Choose the -S over the standard BSL01 whenever the machine is hosed down, runs in a marine or chemical atmosphere, or serves a process that forbids copper contamination. Where weight and cosmetics matter more than corrosion, the resin PAL01 reaches 25 dB; where you also need to throttle exhaust speed, the BESL01-S combines silencing with an adjustable exhaust valve.
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-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, ambient and media temperature -20 to +70 C. This SKU is the 1/8in (01) PT-thread stainless version of the BSL series, with a SUS304 body and a copper-particle sintered silencing element giving 20 dB of noise reduction at 0.5 MPa.
No. The -S suffix swaps the aluminium-alloy body for SUS304; pressure, vacuum, proof pressure, temperature limits, thread sizes and external dimensions all match the standard BSL. The silencing figure does change with material: this stainless 1/8in version is rated 20 dB at 0.5 MPa, and note the sintered element itself is copper-particle, so specify a resin PAL or an all-resin PPA if your process requires a genuinely copper-free part.
