(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)
