AFF / AM Series Compressed Air Purification Filter (Mainstream Line)

Brand: SOLH by Richge Technology 

Series Positioning & Core Functions

     AFF and AM form the core combined air source purification assembly. AFF acts as primary coarse filter to remove solid impurities and condensed water droplets, while AM is precision oil mist separator for micro oil aerosol elimination, improving compressed air cleanliness and fully protecting downstream pneumatic actuators.

  1. AFF Series Main Line Coarse Filter

     -- Filtration precision: 1μm, 99% particle capture rate (upgraded from old 3μm grade)

     -- Core function: Remove large dust, rust debris and bulk condensed water, 99% water separation efficiency as front primary filtration

     -- Cleanliness standard: ISO8573-1:2010 [4:7:4]

  2. AM Series Oil Mist Separator (Fine Filter)

     -- Filtration precision: 0.1μm, 99% micro oil mist capture rate (upgraded from old 0.3μm grade)

     -- Core function: Complete oil mist separation, outlet residual oil concentration ≤1mg/m³ (0.8ppm), fully compliant with oil-free lubrication process requirements

     -- Cleanliness standard: ISO8573-1:2010 [2:7:3]

  3. Shared General Advantages

     -- Ultra-low pressure drop ≤5kPa, energy saving, flow capacity increased by 20% vs conventional models

     -- Lightweight stainless steel liquid storage bowl, maximum weight reduction up to 52%

     -- Visual maintenance reminder: standard built-in clog indicator with red ring to judge filter replacement timing; color-coded filter end caps for quick model identification

     -- Modular cascade design, can be serially connected with AMD / AMH ultra-fine filters to meet multi-grade ultra-clean air demands

Complete Model Naming Rule

Universal Technical Specifications (Standard Test Condition: 0.7MPa, 20℃)

  1. General Common Parameters

     -- Applicable medium: Compressed air (pre-filter ≥40μm required upstream)

     -- Operating pressure range: 0.1~1.0 MPa; burst proof pressure 1.5 MPa

     -- Operating ambient temperature: -5 ~ 60℃ (no ice formation inside bowl)

     -- Drain configuration: Manual drain as standard; auto drain optional via suffix -D

Step-by-Step Selection Guidelines

  1. Filtration Grade Matching Scheme

     -- Ordinary general pneumatic circuits: AFF (1μm coarse filter) → pressure regulator → lubricator

     -- Oil-free precision automation equipment: AFF → AM (0.1μm oil mist separator) → terminal equipment

     -- Ultra-high cleanliness semiconductor / optical process: AFF → AM → AMD (0.01μm ultra-fine filter)

  2. Flow Margin Calculation

     -- Select model with rated flow 1.2~1.5 times higher than total system maximum air consumption; overloaded flow will drastically reduce filtration efficiency and raise pressure loss.

  3. Drain Mode Selection

     -- 24h unattended continuous production, high condensate yield: choose -D auto drain version

     -- Intermittent low-frequency equipment: standard manual drain type sufficient

  4. Port Matching Principle

     -- Consistent filter port size with main pipeline diameter; avoid reducing/increasing diameter to prevent extra pressure drop.

Typical Industrial Application Scenarios

     -- General industrial automation: CNC machine tools, air cylinders, solenoid valve front-end water & oil removal

     -- Food & pharmaceutical manufacturing: oil-free clean air source to avoid product contamination

     -- 3C electronics & coating workshops: eliminate oil mist to prevent surface coating defects and precision component pollution

     -- Air compressor post-treatment system: cascaded with refrigerated / adsorption air dryers to upgrade overall air purity
