AN Series Pneumatic Exhaust Silencer

Brand: SOLH by Richge Technology 

Product Positioning

     SOLH AN series is a dedicated exhaust silencer for all pneumatic systems. Its core functions include exhaust noise reduction, air exhaust purification and oil mist splash suppression. Widely mounted on exhaust ports of solenoid valves, pneumatic cylinders and all air control valves, it is an essential environmental protection & noise reduction accessory for complete pneumatic circuits.

Universal Core Technical Parameters

  1. Applicable Medium: Clean compressed air (NOT suitable for flammable, corrosive toxic gas)

  2. Max Rated Working Pressure: 1.0 MPa (standard resin models)

  3. Operating Temperature Range:

     -- Standard resin type: -10 ~ +60℃ (no icing inside core)

     -- Sintered metal type: Up to 150℃ high temperature resistance

  4. Noise Reduction Performance:

     -- Standard grade: 25 ~ 30 dB(A)

     -- High attenuation special version: ≥35 dB(A)

  5. Optional Construction Materials

     -- Resin type: UL94-V0 flame retardant housing, porous sintered filter core (50~100μm pore size)

     -- Metal type: Copper alloy sintered body, outstanding high temperature & corrosion resistance

  6. Connection Options: M3/M5 metric thread, Rc/PT internal thread, NPT thread, push-in fitting for φ6~φ12 tubing

Internal Structure & Noise Reduction Principle

     -- High-speed exhaust air flows into silencer body; porous sintered core / multi-layer fiber splits airflow into tiny channels to generate friction and sound absorption, effectively attenuate exhaust impact noise.

     -- Double-layer composite design adopted on partial models: inner core for noise elimination, outer shell blocks oil mist splashing while maintaining low exhaust back pressure to avoid cylinder speed loss.

     -- Fully passive mechanical structure, no power supply required, instant noise reduction after simple installation.

3-Step Quick Selection Guide

  1. Match connection interface: Confirm exhaust port thread specification (M5/Rc1/8 etc.) or outer diameter of plastic tubing (φ8/10/12 push-in type).

  2. Match air flow capacity:

     -- Mini series (AN05/AN10): ≤0.4 m³/min

     -- Medium series (AN15/AN20/AN40): 0.8 ~ 1.2 m³/min

     -- Large industrial series (AN500~AN900): ≥2.5 m³/min

  3. Match working environment conditions:

     -- High temperature / frequent rapid exhaust: Select sintered metal AN110 series

     -- Humid dusty indoor workshop: Sealed resin ANA1 series

     -- Maximum noise reduction priority: ANB1 high attenuation silencer series

Installation & Routine Maintenance Instructions

  1. Installation Method

     -- Directly screw onto valve/cylinder exhaust port; outer housing can freely rotate for any orientation layout. Push-in type can be firmly inserted into tubing in one step.

  2. Maintenance Rules

     -- Clogged core cleaning: Blow core reversely with low-pressure clean air or rinse; replace silencer if severe blockage cannot be cleared.

     -- Service life reference: Resin sintered core approx. 10,000 working hours; metal sintered core with ultra-long durable service life.

SOLH Interchange Advantage

     SOLH full AN series models including AN05-M5, AN10-01, AN15-02, ANA1-06 are fully dimensionally interchangeable with SMC original AN silencers, with identical thread size, flow capacity and noise reduction effect, more competitive unit price and faster production lead time for mass purchasing cost optimization.

One Sentence Summary
