China Suppliers Factory PE Plastic Sintered Filter - High-Density Polyethylene for Liquid and Gas Filtration
Product Characteristics
Uniform distribution of pores, wide range of filtration precision (1-100 micron), and strong dirt-holding capacity.
Excellent resistance to acids, alkalis, salts and organic solvents (such as alcohols, ketones), suitable for strong corrosive media.
Pressure-resistant, wear-resistant, can withstand high working pressure (≤ 0.5MPa), not easy to deform or rupture.
Support backwashing, ultrasonic cleaning or chemical cleaning, high reuse rate and low maintenance cost.
Meets food grade (FDA) and medical grade standards, suitable for hygiene-sensitive industries.

Areas of Application
Product Advantages
Strong anti-pollution ability, reduce frequent replacement, save operation cost.
Can be cleaned and used repeatedly, reducing waste generation.
Adapts to a variety of filter housings and supports customized sizes (length, diameter, interface).
No fiber shedding, avoiding secondary pollution.
Maintenance and Upkeep
Backwashing (recommended pressure ≤ 0.3MPa), ultrasonic cleaning (40-50℃ warm water) or immersion in 5% NaOH solution.
According to the differential pressure (ΔP ≥ 0.1MPa need to be cleaned or replaced).
Protected from light and dry environment, avoid contact with ozone or strong oxidizing agents.
Selection Guide
To consider when selecting PE sintered cartridge:
Select the number and size of filter element according to the system flow rate.
Based on the target pollutant particle size (e.g. 1-10μm for suspended particles removal, 20-50μm for activated carbon interception).
Consider temperature, pH, chemical compatibility.
Ensure that the cartridge pressure resistance value is higher than the working pressure.
Frequently Asked Questions
A: It is not recommended to exceed 80℃, high temperature may cause material softening and deformation.
A: When the differential pressure is still higher than 2 times of the initial value after cleaning, or when the flow rate drops significantly, it needs to be replaced.
A: PE is more corrosion-resistant and less costly, but stainless steel is more temperature-resistant (up to 400℃).
A: The maximum working pressure is 0.5 MPa at normal temperature. Ensure that the system working pressure does not exceed this value.
A: You can clean the cartridge using backwashing (recommended pressure ≤ 0.3MPa), ultrasonic cleaning (40-50℃ warm water), or by immersing it in a 5% NaOH solution.
A: The standard filtration precision ranges from 1 to 100 microns, which can be selected and customized based on the target pollutant particle size.
