CXBL series primary efficiency plate filter element

The CXBL series primary efficiency plate filter element is an industrial grade filtration component designed specifically for the front-end pre filtration process of ventilation and air conditioning systems. It adopts a modular plate structure design and is compatible with various standard and non-standard installation frames. It can stably intercept dust particles, fiber flocs, and large particle impurities above 5 μ m, serving as the first protective barrier of multi-stage filtration systems and providing basic protection for back-end medium efficiency and high-efficiency filtration equipment. The overall performance meets the mainstream efficiency level requirements of G3 and G4 under EN779 standard, and can cover the primary filtration needs of the vast majority of civil buildings and industrial scenes.

The CXBL series primary efficiency plate filter element frame can be made of aluminum alloy, galvanized steel plate, or ABS engineering plastic material. Some models adopt a detachable structural design, which facilitates subsequent filter material replacement and frame recycling; The filter material adopts a fluffy and gradually dense structure of polyester synthetic fiber, and the air outlet surface is equipped with diamond or cross shaped metal protective nets for support and reinforcement. While ensuring the filtration area, the airflow path is optimized to control the initial resistance at the rated air volume within a reasonable range. Under normal operating conditions, it can withstand a continuous working temperature of up to 100 ℃. The filter material supports repeated use after multiple cleaning, effectively extending the overall service life. The entire series can provide various thickness specifications such as 15mm, 20mm, 25mm, etc., suitable for different installation spaces and air volume configuration requirements.

The CXBL series primary efficiency plate filter element is widely used in centralized ventilation and air conditioning systems of large public buildings such as office buildings, shopping malls, airports, and sports centers. It is also suitable for ventilation pre filtration in industrial scenarios such as electronic semiconductors, automotive manufacturing, industrial spraying, and ordinary clean rooms. It can also be used for intake protection of large air compressors, coarse filtration of clean return air systems, and front-end pretreatment of local high-efficiency filtration devices, providing stable primary filtration guarantee for ventilation systems in different scenarios.

The CXBL series primary efficiency plate filter element adopts a gradually dense fiber arrangement structure, which effectively reduces initial resistance and energy consumption during ventilation system operation while ensuring rated filtration efficiency; The overall dust holding capacity is excellent, and the replacement cycle can be extended under normal working conditions, reducing operation and maintenance costs; The outer frame and filter material are sealed and bonded together, which can effectively avoid side leakage and ensure the stability of filtration efficiency; The entire series has a high degree of universality and can directly adapt to the vast majority of initial filter installation frames of the same size on the market. Replacement installation can be completed without additional structural modifications, greatly reducing the adaptation threshold.

After installing the CXBL series primary efficiency plate filter element, there is an edge air leakage situation. It is necessary to check the fit between the outer frame of the filter cartridge and the installation frame, adjust the installation position to ensure that there are no gaps around, and if necessary, install a sealing gasket at the fit; If the system's operating resistance rapidly exceeds the rated upper limit, priority should be given to checking whether there are large debris blocking the surface of the filter material on the inlet side. If the resistance still does not decrease after cleaning the debris, it indicates that the dust accumulation inside the filter material is saturated, and a new filter element should be replaced in a timely manner; Local damage to the filter material requires immediate shutdown of the system and replacement with a new filter element of the corresponding specification to prevent unfiltered impurities from directly entering the backend equipment; The filtration effect significantly decreases after cleaning, mostly due to excessive water pressure during the cleaning process that damages the fiber arrangement structure. Subsequent cleaning should use low-pressure air flow back blowing or mild water washing to avoid direct high-pressure flushing of the filter material.
