WKDL series frameless bag filter element

The WKDL series frameless bag filter element is a high-performance filtration product specially designed for medium efficiency air filtration. It is made of ultra-fine synthetic fibers with special weaving precision, and has three core advantages: high dust capture capacity, high dust load, and high breathability. The filter material contains electrostatic fibers, which have excellent interception efficiency for sub micron dust, long service life, and can significantly reduce operation and maintenance costs. The product offers three efficiency levels, G3, G4, and F5 (corresponding to 35% to 65% filtration efficiency), for users to choose according to their needs. The size supports customization and can flexibly adapt to various ventilation and purification systems. It is an ideal choice for pre protection of high-efficiency filters and industrial clean spaces.

The WKDL series frameless bag filter element core is made of galvanized iron or aluminum alloy as the structural outer frame, and metal strips are fixed between each filter bag to effectively prevent filter bag breakage caused by wind shear friction under high wind speed conditions; Each filter bag is evenly distributed with six partitions to avoid excessive expansion and mutual shielding when subjected to wind pressure, ensuring stable effective filtration area and efficiency. The edge of the bag mouth is fused with ultrasonic waves, which has excellent airtightness and eliminates the hidden danger of air leakage. The filter material discards the traditional glass fiber and selects synthetic fiber to avoid discomfort to human body. At the same time, the addition of electrostatic fiber in the filter material makes its filtering performance of submicron dust particularly prominent. The overall structure is lightweight and easy to install, so that one person can quickly complete the replacement operation.

The WKDL series frameless bag filter element can be used for secondary filtration in purification plants, filtration systems with high clean air requirements in electronic factories and spray rooms, air filtration in general commercial buildings, front-end pre filtration of high-efficiency filters, ventilation and purification in automotive painting workshops, air protection in food processing workshops, and other scenarios.

Compared to traditional framed filter bags, the WKDL series frameless bag filter element

significantly reduces the cost of use; The electrostatic fiber technology endows it with the ability to capture submicron dust far beyond the products of the same grade; Ultrasonic fusion process ensures zero air leakage and stable and reliable filtration quality; Lightweight aluminum alloy frame design, time-saving and effortless installation and replacement, outstanding comprehensive cost-effectiveness.

① Decreased filtration effect: The increase in pressure difference is often caused by dust accumulation in the filter bag. When the inlet and outlet pressure difference reaches 0.05-0.1MPa, the filter bag should be replaced in a timely manner to avoid excessive pressure difference causing the filter bag to rupture.

② Filter bag damage: usually caused by improper installation or operation under excessive pressure difference. When replacing, it is necessary to ensure that the filter bag is tightly attached to the support mesh and the bolts are evenly tightened.

③ Edge leakage: Check for cracks at the ultrasonic fusion point. If damaged, replace the entire bag and do not repair it.

④ Filter bag clogging too quickly: It is recommended to install a Y-shaped or basket style pre filter at the front end to intercept large particles and impurities. At the same time, choose the appropriate efficiency level according to the working conditions to avoid overloading caused by a small aperture.
