AF Series Pneumatic Air Filter

AF Series Pneumatic Air Filter | SOLIH Compressed Air Pre-Filter for Air Source Treatment System

Brand: SOLIH by Richge Technology | Industrial Pneumatic Air Purification Filter

1. Product Overview

     The SOLIH AF Series air filter is thecore pre-filter component of the pneumatic air source treatment system. It adopts a dual filtration structure of centrifugal swirl water separation and fiber filter element, which efficiently removes liquid water, oil mist, dust, rust and solid particles from compressed air. It effectively protects downstream pneumatic components such as solenoid valves, cylinders and pneumatic tools from contamination and wear. The AF filter supports modular assembly and can be perfectly combined with AR pressure regulating valves and AL lubricators to form AC two-unit or three-unit air source treatment combinations, serving as the primary purification guarantee for industrial pneumatic systems.

     • AF4000-04D: AF series pneumatic filter, 4000 size, Rc1/2 thread port, automatic drainage type

  Code Rule Explanation

     • AF: Air source filter series code

     • 2000/3000/4000/5000: Body size & flow grade

     • 02/04: Thread port specification

     • D Suffix: Automatic drainage function (no suffix for standard manual drain)

5. Product Core Advantages

     • Dual Efficient Filtration: The front-end centrifugal swirl structure rapidly separates liquid water and large impurities, while the rear 5μm high-density fiber filter element intercepts fine dust and particles, achieving multi-stage deep purification of compressed air.

     • Dual Drainage Options: Equipped with standard manual drainage for conventional intermittent equipment; optional automatic drainage (-D) version for 24-hour continuous operating equipment, avoiding manual maintenance omission.

     • Modular Combination Design: Standard modular structure supports seamless splicing with AR pressure regulator and AL oil mister, freely assembling two-unit or three-unit air source treatment groups, convenient for equipment installation and pipeline integration.

     • Safe & Visual Operation: Equipped with a protective cup cover to prevent cup damage and flying debris; built-in pressure difference display intuitively reflects element clogging status, reminding users of timely replacement and maintenance.

     • Wide Adaptability & Stability: Stable operation under 0.15~0.9MPa wide pressure range and -5~60℃ temperature environment, suitable for various harsh industrial workshop conditions.

6. Typical Application Scenarios

     • Air Compressor Main Pipeline Purification: Centralized air source filtration and purification for factory workshop main gas circuits to improve overall air quality.

     • Automation Industrial Equipment: Supporting purification for automated machinery, machine tools, packaging equipment and electronic production equipment to stabilize pneumatic operation.

     • High-Precision Industry Scenarios: Pre-air source purification for spraying, welding, precision instruments and meters to avoid impurity interference affecting processing accuracy.

     • Pneumatic Component Protection: Used as front-end filter for cylinders, solenoid valves and pneumatic tools to reduce component wear and extend service life.

7. Daily Maintenance Guidelines

     • Regular Drainage: Drain accumulated water in the filter cup periodically to ensure the water level is below the warning line and prevent liquid water from flowing downstream.

     • Timely Element Replacement: Replace the fiber filter element when air pressure difference increases obviously or after 6~12 months of regular use to ensure filtration efficiency.

     • Standard Installation: Install vertically strictly according to the airflow arrow mark on the valve body to ensure normal filtration and water separation performance.

One Sentence Summary

     The SOLIH AF series air filter adopts dual centrifugal and fiber filtration structure, with 5μm high-precision purification, dual drain modes and modular combination function, being the most essential front-end purification component for industrial pneumatic air source treatment systems to protect downstream pneumatic equipment.
