Vacuum cleaner, road sweeper, high-efficiency dust removal filter cartridge 350 * 800

Jingyou Filter 350 × 800 is an efficient self-cleaning dust filter cartridge specially designed for vacuum cleaners and road sweepers. It has an outer diameter of 350mm and a length of 800mm, and is compatible with mainstream sweeper flower plate openings. It uses polyester long fiber non-woven fabric as the core filter material and is equipped with a pulse back blowing self-cleaning system to efficiently intercept road dust, sand particles, and paper scraps, greatly reducing maintenance frequency and consumable costs of cleaning equipment. It is suitable for continuous operation with heavy dust.

The effective filtering area of the filter cartridge is about 10 square meters, and the wide pleat spacing design matches the high air volume requirements of the sweeping vehicle. The filtration accuracy covers 0.3-5 μ m, with a conventional filtration efficiency of ≥ 99.9%. The PTFE coated version can achieve an efficiency of ≥ 99.99% for 0.3 μ m particles, effectively capturing fine dust. Initial pressure difference ≤ 120Pa, it is recommended to trigger a pressure difference of 600-800Pa for dust cleaning. Low resistance design reduces fan load and improves cleaning efficiency. The normal working temperature is -30 ℃~+80 ℃, and the anti-static surface resistance is 10 ⁴ -10 ⁸ Ω, suitable for dry and dusty flammable and explosive risk scenarios. The weight of the filter cartridge is about 4.2kg, and it adopts a six ear quick disassembly structure, which does not require tools or manual disassembly, significantly reducing downtime for maintenance.

The filter material is made of polyester long fiber non-woven fabric, which is resistant to folding and wear, has a large air permeability, and is low in resistance and easy to blow back. The end cap and filter material are tightly bonded with polyurethane foam adhesive, effectively preventing dust leakage. The internal and external support skeleton is made of electroplated galvanized diamond mesh or stainless steel material with a thickness of 0.5mm or more, which has excellent resistance to deformation and collapse, and can withstand pulse blowback impact during cleaning operations. The end is equipped with a closed cell chloroprene rubber sealing ring to ensure no leakage from the equipment flower plate seal and prevent unfiltered air from short circuiting into the system. When the resistance of the filter cartridge reaches the set value, the adaptive cleaning vehicle is equipped with a pulse back blowing system, and high-pressure airflow quickly blows off the attached dust from the inside, quickly restoring the filtering performance and reducing the frequency of manual cleaning and replacement.

This filter cartridge efficiently intercepts incoming dust, protects the cleaning vehicle fan and motor, and reduces the risk of failure and energy loss caused by dust wear. Low initial resistance combined with self-cleaning function, maintaining low operating resistance for a long time, reducing fan loading losses, and improving equipment operating efficiency. Optional PTFE film anti sticking, anti-static, and flame-retardant customized options are available, suitable for different dust and working environments such as urban main roads, industrial parks, and construction sites, extending the service life of the filter cartridge. Widely applicable to sanitation vacuum cleaners, road sweepers, road sweepers, and engineering sweepers, especially suitable for cleaning scenarios with high dust volume and continuous operation.

Conventional road cleaning can choose polyester base version; PTFE film anti sticking is recommended for heavy dust or high humidity working conditions such as construction sites and coal yards to prevent dust adhesion from affecting the cleaning effect; For dry and dusty environments with explosion-proof requirements, it is recommended to choose anti-static or flame-retardant products. During use, it is necessary to cooperate with the pulse system of the cleaning vehicle, regularly check the blowback pressure (0.4-0.6MPa) and cleaning cycle, and ensure that the pressure difference is stable within a reasonable range. It is recommended to conduct integrity testing of filter cartridges every 8-16 months, shorten the testing cycle under complex working conditions, and replace damaged filter cartridges in a timely manner to avoid dust leakage affecting filtration efficiency and equipment safety.
