Primary Efficiency Universal Plate Air Filter (G1-G4 Low Resistance & High Efficiency Type)
What Is A Plate Air Filter?
A: A plate air filter is an air filtration device with a flat, plate-like structure, featuring filter media secured within a rigid frame. The HBL Series Plate Air Filter (Primary Efficiency Universal Plate Air Filter, G1-G4 Low Resistance & High Efficiency Type) is a typical example, designed for primary filtration in air conditioning systems, utilizing multi-layer filter media to capture airborne particles.




Performance and Characteristics
Core Advantages
Classified as Primary Efficiency (G1-G4), it achieves filtration efficiency suitable for initial air purification, effectively intercepting large particles and impurities in HVAC systems.
Designed with Low Resistance and large air volume capabilities, it ensures minimal airflow restriction, reducing energy consumption for air handling systems.
Boasting a Long Life and reusable design, it can be utilized multiple times, lowering long-term operational costs and enhancing sustainability.
Function & Application
Tailored for general air conditioning scenarios, this filter is widely used for primary filtration of air conditioning systems in commercial buildings, civil residences, and other environments. It undertakes the role of initial air purification, preventing large particles from entering deeper into the system and ensuring the long-term and efficient operation of air conditioning units.
