Types of Filter Cartridges
Sediment Filter Cartridges:
These cartridges are designed to remove solid particles such as sand, silt, and rust from water or other liquids.
01
Activated Carbon Filter Cartridges:
These cartridges use activated carbon to adsorb and remove organic compounds, chlorine, and other chemicals from water or air.
02
Membrane Filter Cartridges:
These cartridges utilize a thin membrane to separate particles based on size, effectively removing bacteria, viruses, and other microorganisms.
03
Pleated Filter Cartridges:
These cartridges have a pleated design, providing a larger surface area for filtration and extending the cartridge’s lifespan.
04
Bag Filter Cartridges:
These cartridges consist of a bag-like structure made of filter media, capable of capturing large amounts of contaminants.
05
Structure Material
Filter Material:
High-density polypropylene filter membrane known for its excellent chemical resistance and durability
Support Guide Layer:
Robust polypropylene providing structural integrity and stability
Center Rod/Housing/End Cap:
Precision-engineered polypropylene ensuring seamless integration and longevity
Seal Ring/Gasket:
Made from EPDM and fluorine-containing materials offering superior sealing performance and resistance to extreme conditions
Maximum Operating Temperature:
80°C maintaining optimal filtration efficiency without degradation
Maximum Operating Pressure Difference:
0.42Mpa@25°C ensuring reliable operation under specified pressure conditions
Replace a Cartridge Filter
Turn off the filtration system to ensure safety.
Depressurize the system by opening the air vent valve and draining residual liquid from the housing.
Ensure all necessary tools, including wrenches, cleaning supplies, and replacement cartridges, are ready for use.
Unscrew the housing lid using the appropriate tools. Exercise caution to prevent spillage or contamination.
Detach the alignment plate, springs, and wingnuts that secure the cartridge filters.
Carefully remove the spent cartridges, avoiding any disturbance to the collected debris.
Inspect the removed filters for fouling patterns, which can provide insights into upstream inefficiencies or unexpected contaminant types.
Examine the interior of the housing for signs of corrosion, dirt buildup, or microbial growth.
Clean the housing thoroughly using a compatible cleaning agent. Rinse with deionized water if the application requires high purity.
Allow the housing to dry completely before proceeding.
Remove the protective packaging from the new cartridges.
For depth filters, ensure they are aligned to allow uniform flow through their layered media. For pleated surface filters, confirm proper orientation for optimal contact with the flow.
Secure the cartridges in place using the alignment plate, springs, and wingnuts. Verify that all components are properly tightened to avoid displacement during operation.
Inspect the O-ring for wear or damage. Clean and lubricate the O-ring to ensure an airtight seal. Replace it if necessary.
Reattach and tighten the housing lid securely to prevent leaks.
Gradually introduce liquid into the system to prevent a sudden pressure surge.
Purge trapped air by running liquid through the system until it flows smoothly without interruptions. Close the air vent valve once air is eliminated.
Monitor the system for leaks, pressure stability, and flow rate consistency.
Micron rating: Choose based on the particle size that needs to be filtered
Material: Match media to chemical and temperature resistance
