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
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 (FAQ)
It is not recommended to exceed 80℃, high temperature may cause material softening and deformation.
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.
PE is more corrosion-resistant and less costly, but stainless steel is more temperature-resistant (up to 400℃).
The filtration precision ranges from 1 to 100 μm and can be customized based on your system requirements.
The cartridges are manufactured using high-quality HDPE (High-Density Polyethylene) or UHMW-PE (Ultra-High-Molecular-Weight Polyethylene).
It can safely withstand a maximum working pressure of up to 0.5 MPa under normal temperature conditions.
