HVAC Air Handling Unit (AHU) Air Filter Element Product Description

The HVAC Air Handling Unit (AHU) air filter element is a core filtration component of HVAC systems. Specifically designed to meet the ventilation and purification needs of AHU units, it efficiently intercepts particles, dust and other impurities in the air, ensuring the cleanliness of supplied air and the stable operation of the system. The detailed product description is as follows:

1.Core Position and Function

Compatible with various commercial and industrial AHU units, serving as a key link in air treatment.

Filters suspended particles such as dust, pollen, fibers and PM10 in the air, preventing impurity accumulation from clogging the AHU heat exchanger and increasing fan energy consumption.

Improves indoor air quality, providing clean supplied air for offices, industrial production sites, commercial premises, etc., while reducing equipment wear and maintenance costs.

2.Structure and Materials

Filter Media: Mainly adopts polyester fiber (PET) and polypropylene fiber (PP); some high-efficiency models use glass fiber filter paper. The filter media undergoes electrostatic electret treatment to enhance adsorption capacity for tiny particles with lower resistance.

Outer Frame: Made of moisture-proof hard cardboard, galvanized steel plate or aluminum alloy frame. It matches the installation dimensions of AHU units, featuring both lightweight and structural stability to avoid deformation and falling off.

Support Structure: Internally equipped with spot-welded galvanized steel wire mesh or plastic grille to enhance the stiffness of the filter media, prevent collapse under wind pressure and extend service life.

Sealing Design: The edge of the frame is fitted with sponge or rubber sealing strips to reduce air leakage and ensure no dead ends in filtration efficiency.

3.Performance Characteristics

Filtration Efficiency Classification: Covers full grades of primary efficiency (G1-G4) and medium efficiency (F5-F9), which can be flexibly selected according to AHU usage scenarios to meet different cleanliness requirements.

Low Wind Resistance and High Air Volume: Optimized filter media folding structure with high porosity, initial resistance is only 30-80Pa, without affecting the air volume output and energy consumption performance of AHU units.

Large Dust Holding Capacity: Multi-layer folding design expands the effective filtration area of the filter media, with a dust holding capacity of 150-400g/㎡, extending the replacement cycle and reducing operating costs.

Safety and Environmental Protection: The filter media complies with RoHS standards, no odor and no harmful substances released; flame-retardant models can meet fire safety requirements.

Easy Installation: Standardized size design, directly embedded into the filter slot of AHU units without additional modification, and replacement operation is simple and efficient.

4.Specifications and Customization

Common Sizes: 595×595×21mm, 595×595×46mm, 600×600×100mm, etc., compatible with mainstream AHU unit models.

Customization Support: Special sizes, efficiency grades or sealing methods of filter elements can be customized according to the actual installation space and air volume requirements of AHU units.

5.Application Scenarios

Commercial Buildings: Central air conditioning AHU systems in shopping malls, office buildings and hotels, ensuring air cleanliness in public areas.

Industrial Sites: AHU units in electronic factories, precision manufacturing workshops and pharmaceutical workshops, controlling dust content in the production environment.

Public Facilities: Ventilation and air conditioning systems in hospitals, schools, subways and other places, improving indoor air quality and protecting personnel health.

Data Centers: Filtration of AHU in server rooms, preventing dust from entering equipment and affecting heat dissipation and operational stability.
