I.Features
High - efficiency Filtration: It can effectively intercept paint mist particles generated during the painting process. It has a high filtration efficiency for paint mist particles of different sizes, ensuring that the exhausted air meets environmental protection standards and reducing environmental pollution.
Strong Durability: Made of special filter materials and a well-designed structure, it has excellent anti - clogging and anti - wear properties. It can maintain stable filtration performance during long - term use, reducing the replacement frequency and saving usage costs.
Good Compatibility: It can be adapted to various types of painting equipment and painting working environments. Whether in automotive painting, furniture painting, or industrial parts painting scenarios, it can play a stable filtering role.
Easy Maintenance: Its structure is designed for easy disassembly and installation. When it is necessary to clean or replace the filter medium, the operation is simple and quick, which can effectively reduce equipment downtime and improve work efficiency.
High Safety: The filter material has flame - retardant properties, which can effectively reduce the risk of fire caused by factors such as static electricity during the painting operation, ensuring the safety of the workplace.
II.Operating conditions
Temperature: 0 - 60°C (prolonged >60°C affects performance/lifespan).
Humidity: 10% - 90% non - condensing (condensation risks mold/blockage).
Airflow velocity: 1.5 - 3.0 m/s (too low wastes, too high increases pressure drop, harms equipment/filter).
Chemicals: Resists normal paint - mist solvents/resins; avoid long - term strong acid/alkali exposure (damages materials).
III.Technical parameters
1. Filtration Precision & Efficiency -
Capture efficiency: ≥99.8% for paint mist particles over 10μm, 100% for ≥20μm particles, and 84.5% for ≥5μm particles. Tested per ASHRAE 52.1-1992, the filtration efficiency is 90%, classified as G4 (EN 779) pre-filter.
2. Filter Element & Material Properties
- Element： High water resistance; flame-retardant type available. Made of ultra-strength 3D synthetic material or diamond-shaped paint mist filter cotton (non-glass fiber), self-supporting with a dirt-holding capacity up to 27kg/㎡. The air-facing surface features a 3D honeycomb layered structure for deep filtration.
- Frame: Commonly aluminum alloy or stainless steel; also available in metal frames, shaped as panel, pleated, or bag filters to fit different painting equipment.
3. Dimensions - Standard sizes: 592×592×300×4P, 592×592×600 (6 bags), 287×592×600 (3 bags), 485×485×490, 500×500×500mm, etc. Non-standard sizes can be customized.
4. Initial Resistance & Paint Holding Capacity - Low initial resistance: e.g., 14Pa for 485×485×490mm, 15Pa for 500×500×500mm. Strong paint mist capture capacity up to 27–28kg/㎡.
5. Operating Environment -
Temperature: Heat resistance ≤100℃.
- Humidity: Tolerance ≤100%RH, with excellent moisture resistance.
6. Service Life & Replacement Frequency -
Longer lifespan than traditional paint mist filters, reducing replacement needs. For sticky paints (e.g., varnish), field tests show 10× longer life than traditional products; normally 3–6× longer.
IV.FAQ
Q :Can the DPA Paint Mist Filter be used in high - humidity painting environments?
A:Yes, it can operate in relative humidity up to 100%RH. The filter media is designed for high moisture resistance, preventing deformation or efficiency loss in wet conditions. However, avoid prolonged exposure to condensing environments, as water accumulation may block the filter pores over time.
Q:What is the recommended replacement cycle for the filter?
A:The replacement frequency depends on paint type and airflow. For sticky paints like varnish, it lasts up to 10 times longer than traditional filters (e.g., 6–12 months vs. 1–2 months). For normal paints, replace when the pressure drop reaches 300Pa or when visible paint accumulation occurs. Regular inspection every 2–3 months is advised.
Q:3. Is the filter compatible with solvent - based paints containing xylene/toluene?
A:Yes, the filter media and frame are chemically resistant to common solvents like xylene and toluene in paint mist. However, avoid direct contact with concentrated strong acids/alkalis, as prolonged exposure may damage the materials. Always ensure proper ventilation in the painting area to optimize filter performance.
