Core working principle
Efficient primary filtration protection: With a large aperture structure, it can quickly intercept large particles of impurities such as mud, rust, etc., and the filtration accuracy is mostly above 10 microns, effectively reducing the risk of subsequent precision filter element clogging and extending its service life.
Economical, durable and easy to maintain: It uses low-cost materials such as polypropylene and stainless steel, has a simple structure, is wear-resistant and corrosion-resistant, is easy to clean or replace, and has a low cost of use. It is suitable for long-term continuous filtration scenarios.
Wide range of scene adaptation: It can be used for primary filtration of various fluids such as water, air, and oil, and is suitable for different fields such as industrial production lines, civil water purification, and automobile engines to meet diverse coarse filtration needs.
Precautions
Installation and use specifications: During installation, it is necessary to confirm that the flow direction mark is consistent with the fluid direction to avoid reverse installation that may cause filtration failure; regularly check the pressure difference between the inlet and outlet of the filter element. When the pressure drop exceeds 0.3MPa, the filter element must be cleaned or replaced in time to prevent the system flow from decreasing or equipment damage due to blockage.
Maintenance and storage points: Stainless steel filter elements can be reused by backwashing or ultrasonic cleaning, but strong corrosive cleaning agents should be avoided; disposable filter elements such as PP cannot be reused and must be stored in a dry and clean environment to prevent moisture or contamination from affecting the filtration performance.
FAQ
Q: How to ensure the filtration accuracy and interception efficiency of the coarse filter element?
A: Our coarse filter element adopts a gradient pore size design, with a filtration accuracy covering 10-100 microns, and an interception rate of more than 95% for large particle impurities such as silt, rust, etc. All products have passed the ISO 9001 quality system certification, and each batch undergoes pressure testing and flow testing before leaving the factory to ensure stable performance. For example, in the municipal water supply pretreatment scenario, the actual measurement can reduce the turbidity of raw water from 15 NTU to less than 3 NTU.
Q: Compared with similar products, where is the cost advantage of your filter element?
A: Through large-scale production and process optimization, we have reduced production costs by 20%, and the unit price of bulk purchases is 15%-20% lower than the market average price. The filter element adopts a modular design, which is easy to replace and can reduce 30% of labor maintenance costs. Based on the annual purchase of 5,000 units, the comprehensive cost can be saved by about 120,000 yuan.
Q: What is the service life and maintenance frequency of the Coarse filter element?
A: The service life of the filter element is affected by the impurity content and flow rate of the fluid. Generally, it is recommended to replace the PP melt-blown filter element every 3-6 months, and the stainless steel filter element can be reused for 2-3 years through regular cleaning (recommended once every 2 months). We provide free service life calculation service, formulate maintenance plans according to specific working conditions, and reduce the cost of use.
