FZL series flange type partition medium efficiency air filter element

The FZL series flange type partitioned medium efficiency air filter element is the core filtering component in industrial ventilation and air purification systems. With a stable airflow distribution design relying on the partitioned structure, it can efficiently intercept sub micron dust particles of 1 μ m or more. As an intermediate protective layer between the primary and high-efficiency filters, it significantly reduces the dust load of the back-end high-efficiency filter, extends the consumable replacement cycle of the entire purification system, and provides stable and reliable intermediate filtration guarantee for various scenarios with intermediate and high-end requirements for air cleanliness.

The FZL series flange type partition medium efficiency air filter element adopts a flange integrated outer frame design, which can directly connect with the equipment flange interface for precise docking. High quality galvanized sheet or aluminum foil is used as the internal partition plate to evenly divide the glass fiber or synthetic fiber filter material into regular wavy pleats, maximizing the expansion of the filtration area in a limited space. The outlet side of the filter material is reinforced with a metal mesh to prevent deformation and damage of the filter material under the impact of air flow. The flange contact surface is equipped with an integrated sealing strip to avoid edge leakage after installation. The overall conventional filtration efficiency covers F5-F8 levels, and can withstand continuous working temperatures below 80 ℃. The rated working pressure difference can reach 0.5MPa. It supports customized non-standard specifications according to the installation size on site and is suitable for flanges of various industrial purification units. Connection interface.

The FZL series flange type partitioned medium efficiency air filter element is widely used in the intermediate filtration section of centralized central air conditioning and large fresh air systems, as well as in ventilation and purification systems for electronic manufacturing, precision machining, and ordinary clean rooms. It is also suitable for air compressor station intake pretreatment, gas turbine front-end air protection, painting workshop air supply purification, chemical fiber textile industry air conditioning air supply system and other working conditions, providing pre protection for high-efficiency filtration equipment in the back-end and stabilizing the dust base of air supply.

The FZL series flange type partitioned medium efficiency air filter element flange integrated structure has precise installation and positioning. Compared with ordinary card mounted medium efficiency filters, it has a higher sealing fit and can significantly reduce the risk of air leakage caused by installation gaps; The partition structure ensures a more even distribution of airflow for each layer of filter material, avoiding premature overload and blockage of local filter materials, resulting in better dust holding performance and longer service life under normal operating conditions; The overall structure has strong rigidity, making it less prone to filter material deformation and damage under high air volume and pressure conditions, and providing stronger operational stability; The full range of specifications has strong universality and can be directly adapted to most medium efficiency filter units with flange interfaces on the market, without the need for additional structural modifications to complete replacement.

The FZL series flange type partitioned medium efficiency air filter element quickly exceeds the pressure difference after operation, mostly due to the failure of the front-end primary efficiency filter. A large amount of large particle dust directly enters the medium efficiency filter material, causing rapid blockage. The front-end primary efficiency filter element should be replaced in a timely manner. If the pores of the filter material are completely blocked, a new medium efficiency filter element should be directly replaced; After installation, there is obvious air leakage at the flange joint. Check whether the sealing strip on the flange mating surface is misaligned or aged, adjust the position of the sealing strip or replace it with a new seal, and evenly tighten the docking bolts to solve the problem; The filtration efficiency does not meet the design standards. Check if there is any damage to the filter material or detachment of the partition. If there is structural damage to the filter material, replace it with a new filter element directly; Under high humidity conditions, if the filter material deforms during operation, it is necessary to confirm whether the humidity exceeds the rated tolerance range of the product. For high humidity scenarios, customized versions of water-resistant specialized filter materials can be selected in advance to avoid the filter material from collapsing due to moisture.
