CXPL Series Primary Efficiency Plate Filte element

The CXPL series primary efficiency plate filter element is the first filtration barrier of air purification systems, designed to intercept large particle pollutants above 5 μ m, covering four efficiency levels from G1 to G4, with G4 level achieving an interception rate of 80% to 90% for particles ≥ 5 μ m. The filter element adopts polyester fiber cotton or glass fiber as the filter material, with aluminum alloy frame, galvanized iron frame or stainless steel frame as the support structure. It has four core advantages of low cost, light weight, good universality, and compact structure. The initial resistance is controlled within 30Pa, and the dust holding capacity is ≥ 300g/m ². It is an indispensable pre filtering component in the front end of high-efficiency filters in central air conditioning, clean return air and industrial ventilation systems.

The CXPL series primary efficiency plate filter element adopts a flat plate structure design, with the filter material tightly attached to the metal frame. It is equipped with double-sided spray coated wire mesh or galvanized wire mesh as a protective layer, which is not easy to fall off or deform during use. The filter material can be selected from ordinary polyester fiber cotton (temperature resistance -10 ℃~100 ℃) or glass fiber cotton (temperature resistance up to 350 ℃) to meet the requirements of conventional and high temperature working conditions. The product is divided into two types: disposable and washable and reusable. The disposable filter element can be replaced as a whole when it expires, which is easy to operate; The washable type supports repeated use of water washing or professional cleaning equipment, and the frame and protective net can be retained for a long time, effectively reducing operation and maintenance costs. The overall structure is lightweight, allowing for quick disassembly and assembly by a single person. It is compatible with standard 500 × 500mm and various customized non-standard sizes.

The CXPL series primary efficiency plate filter element is widely used in primary filtration of central air conditioning and centralized ventilation systems, pre filtration of large air compressor inlet air, pre protection of clean room return air systems, air purification in electronic manufacturing and food processing workshops, dust interception in automotive painting and spray painting rooms, as well as places with basic requirements for air cleanliness such as commercial buildings, data centers, semiconductor factories, etc. As the front-end pre filtration of medium efficiency and high-efficiency filters, it effectively extends the service life of back-end equipment.

The initial resistance of the CXPL series primary efficiency plate filter element is as low as 28Pa, which is 15% lower than the industry average, and the energy consumption of the fan is significantly reduced; The progressive density filter material design increases the dust holding capacity by 20% compared to ordinary products and reduces the frequency of replacement; Aluminum alloy and stainless steel frames are optional, balancing lightweight and corrosion resistance; G1 to G4 are fully covered, supporting standard and non-standard customization, with strong adaptability and outstanding comprehensive cost-effectiveness.

① Decreased filtration efficiency: Resistance increases due to dust accumulation. When the inlet and outlet pressure difference reaches 150-250Pa or the measured cleanliness does not meet the standard, it should be replaced in a timely manner to avoid damage to the filter material caused by overpressure operation.

② Deformation or detachment of filter material: usually caused by improper installation or airflow impact. When replacing, ensure that the filter material is completely in contact with the frame and tighten the protective net.

③ Edge air leakage: Check if the connection between the frame and the pipeline is tightly sealed, and install sealing strips if necessary.

④ Blockage too quickly: It is recommended to install a pre filtration device at the front end to intercept large particles of impurities, and choose G2 or G3 levels reasonably according to the dust concentration to avoid overloading caused by too small pore size.
