Avoid a wrong match
- Plain ordinary BSL/BSLM/BESL is not auto-converted to -S.
- SUS304 body does not establish all-304, copper-free or chemical suitability.
- No M5 BESL, added thread suffix, fixed flow or guaranteed noise result.

Catalogue Technical Specifications
| Three distinct functions | BSL-S is the universal silencer; BSLM-S is the mini silencer; BESL-S is the adjustable throttling silencer. The combined family retains these geometries and its stainless-fittings subgroup. -S is the published SUS304 material suffix; a plain BSL/BSLM/BESL code is not automatically this stainless-body version. |
| Published connection matrix | Fourteen combinations: BSL M5 and 01–04; BSLM M5 and 01–04; BESL only 01–04. M5 means M5×0.8; 01/02/03/04 mean nominal 1/8, 1/4, 3/8, 1/2 inch connections. This source labels R and nominal fractions without establishing a selectable G/PT/NPT suffix; confirm actual thread form from the label and mating port. No BESLM5-S, 06/08 or generic all-thread matrix. |
| Material details differ between references | The ordering suffix and structure identify the silencer body as SUS304. BSL drawing explicitly labels its sound-absorbing cover copper particle sintered; BESL table lists a copper particle sintered silencer ring, aluminum-alloy adjusting cap, throttling column, locking cap and locking ring, and SUS304 body. The feature text says suitable for copper-prohibiting conditions, which conflicts with those component labels. Copper-free or all-304 construction and corrosion/chemical compatibility require the actual BOM and application confirmation. BSLM component materials are not separately itemized. |
| Operating limits | Operating pressure 0–1.0 MPa, separately proof pressure 1.5 MPa; temperature −20 to 70°C. Source negative-pressure notation −750 mmHg (10 Torr) retained as written, not treated as signed-unit equality. These are the stainless silencer source values, not the 150°C JT2 or ordinary silencer values. Actual medium, contamination, backpressure and installation duty require inquiry confirmation. |
| Source noise reference | Specification heading is silencing effect dB at 0.5 MPa: M5 BSL and BSLM rows 15 dB; all 01–04 BSL/BSLM/BESL rows 20 dB. This is the published silencing effect under the stated pressure, not an absolute sound level, guaranteed installed reduction or site test certification. The ordinary 13 dB and PAL 25 dB ratings do not apply. |
| Dimensions and adjustment envelope | Rows ordered M5/01/02/03/04: BSL C 19.5/24/30/38.5/46 mm, H 8/12/15/19/22 mm, weight 2.5/7/14/24.5/37.5 g; BSLM C 9.5/11/13.5/15.5/19 mm, same H, weight 2.5/5/9/15/25.5 g. BESL 01/02/03/04 C max/min 40.5/33, 42.5/35, 49/41.5, 59.5/52 mm; H 12/14/17/24 mm, weight 11.5/17/30/66 g. L for M5/01/02/03/04 is 3.5/6/8/9/10.5 mm; BESL starts at 01. Confirm thread engagement, wrench access and BESL full adjustment envelope. |
| Flow and throttling | BSL and BSLM have separate inlet-pressure versus outlet-flow curves. BESL has its own inlet-pressure chart with throttling bolt completely open and a separate controlled-flow-versus-turns chart. The turns chart does not specify its test pressure; a 0.5 MPa test condition or a fixed flow rating is not established for every model. BESL controls exhaust flow by adjustment; no safety, pressure-relief or zero-leak shutoff function is verified. |
| Information for quotation | Send complete -S code, original label, nominal connection and actual thread form, required fixed/mini/adjustable function, pressure/temperature/medium, copper-free or material requirements, installed dimensions/photos, quantity and destination. Actual application fit, availability and delivery are confirmed on inquiry; catalogue photographs do not establish stock. |

Matching Questions
Are -S silencers all stainless steel and copper-free?
The ordering suffix and structure identify the silencer body as SUS304. BSL drawing explicitly labels its sound-absorbing cover copper particle sintered; BESL table lists a copper particle sintered silencer ring, aluminum-alloy adjusting cap, throttling column, locking cap and locking ring, and SUS304 body. The feature text says suitable for copper-prohibiting conditions, which conflicts with those component labels. Copper-free or all-304 construction and corrosion/chemical compatibility require the actual BOM and application confirmation. BSLM component materials are not separately itemized.
Can BESL-S use the mini M5 row or a fixed flow rating?
No. BESL-S publishes only 01–04 and its own adjustable envelope. Flow depends on pressure and adjustment; send the code and operating duty for confirmation.
