Disposable integrated air filter

The disposable integrated air filter is a set of filtration functions and structural design in one of the air purification equipment, its core feature is the convenience of "one-time use, overall replacement", while through efficient filtration materials and sealing structure to achieve accurate interception of particles in the air. The following is a detailed analysis of the technical principles, application scenarios, performance parameters, and selection suggestions:
First, core technology and structural design
Closed modular design
The filter is usually composed of a photostatic chamber and a driverless high-efficiency filter, with an aluminum frame or galvanized steel shell. The interior is completely sealed by hot melt adhesive or polyurethane adhesive to ensure that there is no side leakage in the airflow path. For example, Hongyuan Purification products are lightweight (standard height 150mm) and have fire safety through anodized aluminum alloy boxes and PE insulation foam (fire rating B1).
Filter materials and efficiency
Filter material: The mainstream use of ultrafine glass fiber filter paper (such as H13, H14 grade) or polyester fiber, through the dense fold structure to increase the filter area (up to 2-3 times the plate structure), taking into account the dust capacity and low wind resistance.
Efficiency level:
Initial effect (G3-G4): Filter more than 5 microns of particles (such as dust, and hair), an efficiency of about 85%-90%.
Medium efficiency (F7-F9): Intercepts 1-5 micron particles (such as pollen and mold spores) with an efficiency of 90%-95%.
High efficiency (H13-H14): The filtration efficiency of 0.3 micron particles is 99.97%-99.999%, suitable for clean room end filtration.
Ultra-high efficiency (U15-U17): can filter 0.12-micron particles, efficiency ≥99.9995%, for semiconductor, medical, and other high-demand scenarios.
Installation and maintenance
Plug and play: Support ceiling lifting or color plate installation, some models (such as the Warnewind HEPA-BOX) equipped with a tool-free fixture, can be directly from the room to replace the filter without removing the air pipe.
Pre-filtration requirements: To extend the life, it is recommended that the front end be configured with an F8 medium effect filter (colorimetric efficiency of 90%-95%) to intercept large particle pollutants.
2. Core advantages and application scenarios
Four core advantages
Maintenance-free: The disposable design avoids secondary pollution caused by cleaning and reduces maintenance costs by more than 60%.
High tightness: The closed structure passes the air leakage test to ensure the air quality of the clean room (such as 10,000, or thousand).
Energy saving and high efficiency: Low resistance design (initial resistance 50-150Pa) combined with large air volume (surface wind speed up to 3.05m/s), reduce the energy consumption of the air conditioning system.
Flexible customization: Support non-standard dimensions (such as tuyere diameter 250-350mm) and special requirements such as fire and moisture resistance.
Typical application scenario
Medical field: Hospital operating room, ICU ward (need H14 filtration, intercept bacteria, viruses).
Industrial manufacturing: microelectronics workshop (U15 level, control 0.1 micron particles), pharmaceutical factory aseptic room (HEPA level).
Commercial buildings: Central air conditioning system (F7-F9 grade, filter PM2.5, allergens) for hotels and office buildings.
Temporary clean space: short-term use scenarios such as exhibitions and temporary laboratories to avoid long-term maintenance costs
