ZZJL series bracket type medium efficiency filter element

The ZZJL series bracket type medium efficiency filter element is a high-performance air filtration element specially designed for the intermediate filtration stage of ventilation and purification systems. It uses synthetic fiber non-woven fabric or glass fiber as the core filter material, combined with a sturdy metal bracket structure, and can efficiently capture dust, pollen, smoke, and various suspended particles with a particle size of 1-5 μ m. The filtration efficiency covers F5 to F9 levels (60%~95%). This series of filter cartridges integrates high dust holding capacity, low resistance, and washable regeneration. It can be used as an independent medium efficiency filtration unit or combined with primary and high-efficiency filters to form a complete graded purification system, providing stable and reliable air quality assurance for fields such as electronic manufacturing, food processing, commercial buildings, and public facilities.

The outer frame of the ZZJL series bracket type medium efficiency filter element is made of aluminum alloy or galvanized steel plate that has undergone anti-corrosion treatment. The interior uses a professional bracket structure to support the filter material, effectively preventing deformation or rupture of the filter material at high wind speeds and ensuring full utilization of the filtration area. The filter material is mainly composed of double-sided laminated synthetic fiber non-woven fabric, and some models can choose fiberglass composite material. The initial resistance is controlled within 80Pa, and the final resistance does not exceed 160Pa. The dust holding capacity is above 250g/m ². The overall design adopts modular design, with standard dimensions suitable for most ventilation systems, supporting non-standard customization, easy installation and replacement, and a service life of up to 6-12 months. The filtration efficiency retention rate after cleaning is not less than 85%.

The ZZJL series bracket type medium efficiency filter element is widely used in intermediate filtration of central air conditioning systems, return air purification of clean rooms, pre-treatment of electronic and semiconductor workshops, food and beverage processing workshops, ventilation systems of commercial office buildings and large public buildings, dust interception at the front end of automotive painting production lines, and other scenarios. It is particularly suitable for semi clean environments with high air quality requirements but no need for high-efficiency filtration at the end.

The ZZJL series bracket type medium efficiency filter element has a scientifically designed bracket structure, with even tension of the filter material, no deformation at high air speeds, and a larger effective filtration area; Secondly, it has a high dust holding capacity and low resistance, with an initial resistance of≤80Pa, resulting in lower energy consumption during system operation; Thirdly, the filter material can be washed and reused, with an efficiency retention rate of ≥ 85% after cleaning, and significant cost advantages throughout the entire lifecycle; The fourth is the modular quick disassembly design, which eliminates the need for professional tools for replacement and maintenance, and has a short downtime; The fifth is to support non-standard customization and flexibly adapt to various irregular installation spaces.

Decreased filtration efficiency: This is often caused by the saturation of dust in the filter material. It is recommended to monitor the pressure difference and clean or replace it promptly when it exceeds the final resistance of 160Pa. Bracket deformation or filter material damage: usually caused by high wind speed or improper installation. It is necessary to verify whether the system air volume matches, and ensure that the bracket buckle is locked in place during installation.

Leakage at the sealing point: Check whether the sealing strip between the bracket and the box is aging or misaligned, replace the polyurethane sealing strip in a timely manner, and re tighten it. Abnormal increase in system resistance: Check if there is a situation where multiple filter cartridges are blocked at the same time. It is recommended to develop a regular maintenance plan and rotate the cleaning of differential pressure data.
