What is a Pleated Cartridge Filter?

Pleated cartridge filters are surface filters that prevent sediments from passing though the surface. The cartridge media is pleated, so that the surface area of the filter increases and holds a large amount of sediments. The pleated media is engineered to form layers that enable absolute filtration while also allowing it to capture particles of different sizes. Therefore – It aids fine filtration in both nominal and absolute filtration efficiency. The micron rating of pleated cartridge filters is more precise than string wound or melt blown variants – hence it is the popular choice for critical applications and production of high-purity and sterile water.

Technical Specifications of Pleated Filter Cartridge From Gopani

Length Variants Available Engineered Core Filter Medium
10”, 20”, 30”, 40”, 50”, 60”, 70” in standard and jumbo sizes High strength Polypropylene Polypropylene, PTFE, PES, Nylon

What is a Polypropylene (PP) pleated filter cartridge?

A pp pleated cartridge filter is constructed using 100% polypropelene media. Polypropelene is known for its chemical compatibility. The multilayered pleated polypropylene structure enables graded filtration and high dirt holding.

What is Polyester (PE) pleated filter cartridge?

PE pleated filters made from polyester- a 100% synthetic media, are washable and hence have a long service life. This also makes them a cost-effective alternative. The pleated variant is perfect for dirt, sand, silt and sediment filtration.

What is a Polytetrafluoroethylene (PTFE) pleated filter cartridge?

The PTFE pleated cartridge filters are highly popular in chemical and pharmaceutical applications due to their extraordinary resistance to temperature and chemicals. As the Polytetrafluoroethylene is a hydrophobic material the pleated PTFE filters are widely used in Oil and gas applications, where process fluids have to be protected from humidity and steam.

What is a Polyethersulfone (PES) pleated filter cartridge?

The pleated polyethersulfone membranes are best suited for fine filtration of aqueous solutions especially in sterile applications.

What is a Nylon pleated filter cartridge?

Nylon is hydrophilic in nature; hence the nylon pleated filter cartridge is yet another variant that is solvent resistant. And is widely used for filtering both aqueous and organic solvents. The nylon pleated membranes are strong and flexible. Nylon 66 is one of the finest engineering polymers with good mechanical strength, thermal resistance, and is compatible with a wide range of fluids. 

What is a Fiber glass pleated cartridge filter?

The fiber glass pleated cartridge filters are known for superior flow characteristics, very low pressure drops and corrosive liquids. This makes the filter cartridges best for use in chemical and oil and gas applications.

What is a Backwashable pleated cartridge filter?

Backwashable pleated cartridge filters are the filters that are cleaned by reversing the flow through the cartridge element. The reverse flow removes the accumulated particles from the outer surface of the cartridge filter; hence the filter media does not clog fast and the filter cartridge gives a very long service life.

Applications of pleated cartridge filters

Pleated cartridge filters suit duties that need fine, absolute-rated filtration at high flow with long service life. Typical applications include:

  • Food and beverage: water treatment, clarification and pre-bottling filtration
  • Pharmaceuticals and biotech: pre-filtration and non-sterile process filtration
  • Microelectronics and semiconductors: high-purity and ultrapure water polishing
  • Chemicals, paints and coatings: resin, solvent and ink filtration
  • Water treatment and RO systems: final polishing ahead of membranes
  • Oil and gas: amine, glycol and process fluid filtration

Frequently Asked Questions

What is a pleated cartridge filter?

A pleated cartridge filter is a surface filter whose media is folded into pleats to create a large filtration area. The extra surface holds more dirt, delivers higher flow at a lower pressure drop, and lasts longer than a comparable non-pleated cartridge.

Is a pleated cartridge filter a surface or a depth filter?

It is a surface filter. Particles are captured on the outer pleated surface at a defined micron rating, which makes pleated cartridges well suited to absolute-rated, repeatable filtration. Depth filters such as melt blown and string wound trap particles throughout their thickness.

What materials are pleated cartridge filters made from?

Common media include polypropylene (PP), polyester (PE) and PTFE, each chosen for chemical compatibility and temperature range. PP suits general water and chemical service, PE handles higher temperatures, and PTFE suits aggressive chemicals and solvents.

What micron ratings are available?

Pleated cartridges are typically available from about 0.2 to 100 microns, in absolute or nominal ratings, so they can be matched to fine polishing or coarser pre-filtration duties.

When should I choose a pleated cartridge over a melt blown or string wound filter?

Choose a pleated cartridge when you need higher dirt-holding capacity, longer life, higher flow, or an absolute micron rating. Choose a depth cartridge such as melt blown or string wound for lower-cost, high-load pre-filtration.
