Sub High Efficiency Air Filter (No Partition, High Dust Holding, High Airflow for Commercial & Industrial HVAC Pre-Filtration)
What Is A Sub High Efficiency Air Filter?
A: A sub high efficiency air filter is a versatile filtration device designed for intermediate to high-level air purification. It features a no-partition structure with filter media like ultrafine polypropylene or glass fiber paper, enabling efficient particle capture, large dust-holding capacity, and compatibility with diverse airflow requirements. It is tailored for heating, ventilation, and air conditioning (HVAC) systems in commercial and industrial buildings.
Performance and Characteristics
Core Advantages
Diverse Filter Media & Efficiency Ranges: Utilizes ultrafine polypropylene or glass fiber filter paper, achieving efficiencies from medium (F6–F7) to sub-high (F8–H10), with filtration rates from 60% to over 99% (at 0.3μm, counting method).
High Air Volume & Low Resistance: The no-partition design allows for high airflow handling (up to 1800 m³/h) with low initial resistance (≤100Pa for F8 class), reducing energy consumption in HVAC systems.
Large Dust Capacity & Durable Construction: Made of moisture-proof, fire-resistant glass fiber with thermoplastic rubber barriers, it maximizes filter media utilization, ensuring a long service life and reduced maintenance frequency.
Function & Application
It is widely used in air-conditioning systems for heating and ventilation in industrial and commercial sectors, including large civil buildings like office buildings, hospitals, malls, and airports. It also serves as pre-filtration in ventilation and air conditioning systems for ordinary industrial plants or clean centralized ventilation systems, protecting downstream equipment and maintaining air quality.
