Panel Primary Air Filter

Product Description of Panel Primary Air Filter

The panel primary air filter is a commonly used primary filtration device in air filtration systems, mainly designed to capture particles of 2μm and above, dust, and various suspended solids in the air. It serves as the primary filtration unit for air conditioning systems or the pre-filtration component in multi-stage filtration systems.

Appearance & Structure

Frame Material: Common options include aluminum profile, folded aluminum plate, galvanized frame, stainless steel frame, and paper frame, featuring sturdiness, durability, and light weight.

Filter Media: Polyester synthetic fiber is widely adopted, with a fluffy air inlet surface and a dense air outlet surface. This structure ensures high filtration efficiency while providing a large dust holding capacity. Non-woven fabric and nylon mesh are also available as alternatives.

Protective Mesh: Generally made of powder-coated square mesh, powder-coated diamond mesh, or galvanized square mesh, it functions to fix and protect the filter media.

Product Features

Compact & Lightweight Structure: The optimized structural design ensures light weight, facilitating easy installation, disassembly, and transportation, which helps save installation space and labor costs.

High Filtration Efficiency: Rated at filtration efficiency levels G1, G2, G3, and G4 (in accordance with EN779 standard), it can effectively filter large particulate pollutants in the air, laying a solid foundation for subsequent medium and high-efficiency filtration.

Large Dust Holding Capacity: The reasonable pleat design of the filter element and the special structure of the filter media expand the effective filtration area, thereby increasing the dust holding capacity and extending the service life of the filter.

Reusable Performance: Certain types of panel primary air filters can be cleaned (e.g., by air gun blowing) and reused, reducing the operational costs.

Strong Airflow Adaptability: It can meet the operating airflow requirements of various ventilation systems, making it suitable for a wide range of applications.

Technical Parameters

Dimension Specifications: Common sizes are 595mm×595mm×46mm, 495mm×595mm×46mm, 295mm×595mm×46mm, etc. Customized dimensions are also available upon customer requests.

Rated Airflow: The rated airflow varies with different dimensions. For instance, the 595mm×595mm×46mm filter can reach a rated airflow of 3200m³/h.

Initial Resistance: Approximately 30–40Pa under standard conditions.

Final Resistance: Typically set at 250Pa.

Operating Temperature: Ranges from -10℃ to 100℃ in general, subject to the specific materials of the filter media and frame.

Application Fields

Central Air Conditioning Systems: Used for pre-filtration in fresh air handling units and ventilation systems, protecting air conditioning equipment and improving indoor air quality.

Industrial Sector: Applied in the pre-filtration of large air compressors, spray painting systems, gas turbines, and other industrial equipment.

Commercial & Public Buildings: Suitable for the centralized ventilation systems of office buildings, shopping malls, hospitals, airports, and other public places.

Clean Rooms: Serves as the pre-filtration device for high-efficiency filters to prolong their service life.
