IEF products are used in large shopping malls, villas, underground parking lots, and household ventilation systems. They are air purification modules for air ducts. Air enters from one end and passes through our IEF air purification module, filtering out large particles, hair and dust. High voltage kills viruses and bacteria. The collector adsorbs fine particles and dust, and the catalytic carbon mesh absorbs odors. Cleaning should be carried out in a timely manner according to the air environment conditions of the installation site. Clean the primary filter screen, generator and collector.

Key Features of the Large-scale HVAC Air Purification Module
1. Technology Advantages
TPA Core Technology: Powered by Airdog’s proprietary ionization and collection system, replacing traditional HEPA with long-lasting, high-efficiency air purification.
Filterless & Washable: No consumable filters required, washable collector plates reduce maintenance and operating costs.
Germ & Virus Elimination: The ionization process effectively inactivates bacteria and viruses, ensuring safer environments for high-traffic and sensitive areas.
2. System Integration
Modular Design: Scalable modules to fit various sizes of malls, factories, hospitals, schools, and parking garages.
HVAC Compatible: Easy integration into central HVAC, fresh air systems, and industrial ventilation.
High Airflow Capacity: Engineered for large spaces with strong ventilation while maintaining purification efficiency.
3. Value & Benefits
Energy-efficient: Low resistance and low energy consumption, reducing HVAC operating costs compared to HEPA.
Improved Air Quality: Removes PM2.5, VOCs, pathogens, and odors, creating a healthier indoor environment.
Versatile Applications: Suitable for commercial, industrial, residential villas, underground parking, and educational facilities.
The four-layer structure of the product:
1. Primary Filter: Filter out large particles such as hair and dandruff.
2. IEF wire frame; make the particles positively charged, generating a high concentration ionized field.
3. IEF collecting plate; highly efficient adsorption of positively charged particles, 14.6nanometers for ultimate purification.
4. Catalytic filter. Absorb odors and decompose harmful gases such as formaldehyde and TVOC.
Special note: The four-layer structure of this product is exactly the same as the four-layer filtration technology principle of Airdog TPA.
