Industrial Filtration Products

Pleated Cartridge Filter

Pleated Cartridge Filters are designed for high-volume industrial filtration in demanding applications. They feature a pleated design that maximises filtration area within a compact housing, enabling high flow rates and extended service life. Available in multiple diameters and lengths, they are constructed with a range of filter media including Nylon66, PTFE, PES, PP, PVDF, MCE, GF, and PFA. All cartridges are integrity tested and flushed with ultrapure water before shipping, ensuring reliable performance in critical processes.

How It Is Made

Manufacturing And Quality Control

Manufacturing Process

Pleating of filter media with precision folding to maximise surface area
Thermal welding of media to support layer and end caps without adhesive
Assembly of core, cage, and end cap into the housing
Integrity testing of each cartridge before packing
Flushing with ultrapure water to remove manufacturing residues
Final inspection and packing in protective packaging

Quality Control

Each cartridge undergoes 100% integrity testing before shipment
Sealing and structural integrity verified under operating pressure and temperature
Filter media and core materials inspected for consistency and uniformity
Flushing with ultrapure water confirmed to remove particulates and extractables
Final visual inspection for defects in pleating, welding, and housing

Comparison

Compared With The Alternatives

Versus Flat sheet cartridge filters

The pleated design provides significantly higher filtration area in the same footprint, improving flow rate and extending service life

Versus Adhesive-bonded cartridges

Thermally welded construction eliminates adhesive residues, reducing extractables and contamination risk

Versus Standard cylindrical filters

The pleated structure allows for greater surface area and lower pressure drop, especially under high flow conditions

Versus Non-integrity tested filters

Each cartridge is 100% integrity tested before shipping, ensuring consistent performance and reliability

Use Guide

How To Use It

Select the filter media based on chemical compatibility: PTFE and PFA for aggressive chemicals, PES and PP for aqueous solutions, PVDF for high-temperature and corrosive liquids
Choose the diameter and length to match the housing and system flow requirements
Ensure the connection type matches the system's inlet/outlet configuration
Verify that the maximum operating temperature and pressure are not exceeded
Flush the cartridge with appropriate solvent or water before first use if required
Replace the cartridge when pressure drop increases or flow rate decreases significantly
