  (For Paint Booths, Dry Filter Spray Booths, DPA Paint Mist Filtration Systems) 

   1. Core Features

  ✅ Three-Stage Filtration System

  - Pre-filtration layer: Stainless steel mesh intercepts particles ≥100μm  

  - Primary filtration layer: Gradient-density polyester fiber bags (6-12 bags)  

  - Post-filtration layer: Fiberglass cotton captures escaped paint mist  

   

  ✅ Ultra-High Filtration Performance

  - Paint mist capture efficiency: 95-99%

  - Initial resistance: 80-150Pa  

  - Paint-holding capacity: 2.5-4kg/m² 

   

  ✅ Smart Operation & Maintenance Design  

  - Equipped with differential pressure monitoring system (±5% accuracy)  

  - Optional automatic pulse-jet cleaning device  

  - Fire resistance rating: DIN 4102 B1  

   

  ✅ Industrial-Grade Durability 

  - Frame material: Galvalume steel / 304 stainless steel 

  - Solvent resistance: Passes xylene immersion test

  - Operating temperature range: -20℃ to 80℃

   

  2. Filtration Mechanism

  - Inertial Impaction: Paint particles collide with fibers and are captured.  

  - Interception Effect: Gradient-density fiber layers progressively trap particles.  

  - Adhesion: Resin-treated fibers enhance paint mist adhesion.  

  - Electrostatic Adsorption: Electret treatment improves fine particle capture.  

  3. Typical Applications  

  - Automotive: Vehicle coating lines, bumper spraying  

  - Rail Transit: Train carriage painting  

  - Industrial Equipment: Construction machinery, agricultural equipment coating  

  - Furniture Industry: Wooden furniture automated spraying lines  

  - Electronics: Home appliance shell spraying  

   4. Selection Guide

  Paint Type Compatibility

  - Water-based paint: Choose moisture-resistant filter bags

  - High-solid paint: Select thickened bags (600g/m²)

  - UV paint: Opt for UV-resistant models

  Airflow Calculation 

  - Recommended face velocity: 0.5-1.0m/s

  - Formula: Q = 3600 × V × A × 0.7

  System Configuration  

  - Pre-stage: G4 panel filter  

  - Post-stage: Activated carbon adsorption unit (for VOCs treatment)  

  5. Maintenance & Management

  Replacement Cycle  

  - Standard conditions: 3-4 months 

  - High-load conditions: 1-2 months 

  Smart Monitoring  

  - Alarm triggered at ≥400Pa differential pressure

  - PLC control system recommended 

  Safety Protocols

  - Power must be disconnected during replacement

  - Discarded filter bags classified as hazardous waste (HW12 code)
