Here is the professional English translation of the Industrial Air Filter technical documentation:
I. Core Types & Performance
-
Bag Filters
- Structure: Seamless-bonded melt-blown microfibers; aluminum alloy/galvanized frames. Temperature resistance: 80°C; humidity resistance: 100% RH
- Efficiency: G3-G4 (Coarse)/F5 (Medium) (EN 779 standard); flame-retardant class F1
- Applications: Hospital cleanrooms, electronics workshops, paint booth pre-filtration
-
Pleated Panel Filters (Initial Grade)
- Design: Layered/pleated synthetic or glass fibers; rigid waterproof cardboard or metal frames
- Features: Low resistance, high dust capacity; thicknesses: 20/46/96mm (1"/2"/4")
- Scenarios: HVAC pre-filtration, compressor ventilation systems
-
Pneumatic FRL Units (Filter-Regulator-Lubricator)
- Components: Air filter + pressure regulator + lubricator (core compressed air system module)
- Parameters: Filtration precision 50-75μm; pressure range 0.5-10MPa; industrial air-end purification

III. Selection & Maintenance
- Scenario Matching:
- High-dust environments (e.g., welding shops): Bag filters + pre-filter panels
- Compressed air systems: Mandatory FRL unit installation (filtration + regulation + lubrication)
- Replacement Cycle:
- Initial filters: 1-3 months (when ΔP >50% initial value)
- HEPA filters: 6-12 months (based on particulate monitoring)
