AirTAC BESL ordering thread matrix official English reference
Helpful for Model Matching:
| Function and identity | BESL is a threaded silencer with adjustable exhaust throttling, not BSL general, BSLM mini, PAL/PALM plastic, PPA plug-in or BESL-S stainless. Adjustable exhaust flow changes backpressure and actuator behavior; confirm the circuit, not a universal speed-control or safety valve claim. |
| Ordering and threads | BESL01=1/8,02=1/4,03=3/8,04=1/2 threaded connection. No BESL M5 row. No color selector for BESL: D belongs to PAL/PALM only. Current shared ordering specifies thread size, not an encoded PT/G/NPT standard; confirm installation thread form and sealing rather than silently supplying G/T or treating all thread systems interchangeable. |
| Operating limits | Operating0–1.0 MPa, proof1.5 MPa separately, temperature−20 to70°C. Negative pressure source notation−750 mmHg(10 Torr) is retained as published, not converted into an equivalence of signed units. Confirm actual exhaust/vacuum duty, backpressure and contamination. No universal chemical/fluid compatibility is established. |
| Material scope | Own BESL structure lists adjusting cap, throttling column, locking cap/ring and body as aluminum alloy; silencer ring is sintered brass particles. Do not describe BESL as all-brass, all-stainless or the BSL porous body. No material substitution or safety certification inferred. |
| Flow and installation envelope | Own chart relates inlet pressure to outlet flow with throttling bolt completely open; separate chart relates turns to controlled-channel flow. These are curves, not a fixed flow rating or linear turn-to-flow law. BESL01/02/03/04 total C max40.5/42.5/49/59.5 mm, min33/35/41.5/52 mm; hex H12/14/17/24 mm. Leave adjustment/access clearance and confirm exhaust circuit. |
| RFQ inputs | Send exact BESL code or readable label, exhaust port/thread form, valve/cylinder circuit, actual pressure/vacuum/temperature, desired flow/noise behavior, installation/adjustment space, quantity and destination. Supply and fit are confirmed on inquiry; no emergency-stop, pressure-relief or safe-load function implied. |
