More media in the same shell. That is the whole trick, done properly.

What a wrong pleated element costs
A pleated element asked to take bulk solids blinds in days, and the finest, most expensive stage in the train becomes the one changed most often. A membrane cartridge that cannot survive the plant's steam or autoclave cycles loses integrity and has to be requalified. Gels and agglomerates plug thin media long before its area is used. In a power plant, fines that pass the condensate pre-filter reach the polisher resin. In each case the cost is not the cartridge but the batch, the membrane or the outage it was meant to protect.
Selecting the element
Put bulk solids somewhere else
Pleated elements are for efficiency and fine ratings. Take heavy bulk solids out first with a depth cartridge or a bag; most trains that work use both.
Choose the media for the fluid
PP for general aqueous and chemical duty; PES for sterile aqueous filtration; PTFE for aggressive solvents, gases and heat; PVDF for sterilising-grade duty; Nylon 66 where its solvent compatibility matters; glass fibre for high efficiency in brine, oily water, acids and diesel.
Set rating and efficiency
Nominal grades (NE) for general duty, high-efficiency and beta 5000 grades for process streams, membrane grades from 1.0 down to 0.05 micron for final and sterile-adjacent filtration.
Pick the format
Standard 2.5 inch elements for most housings, jumbo for more area per housing, 60 and 70 inch CPU elements for condensate polishing, 6 inch HF elements for large flows, capsules for laboratory and pilot scale.
Check sterilisation and documentation
If the element will be autoclaved or steamed in place, confirm the cycle count on the membrane table, and tell us what documentation your QA team files.

No part-number format is published for Clarypleat; orders are specified by variant, rating, length, end fitting and O-ring.
Conditions behind the numbers
Temperatures and differential pressures are stated together on each data sheet, and a pressure limit holds only at its stated temperature. HF flows are suggested water flows in ideal conditions. Sterilisation cycle counts are stated values to be confirmed on your own cycle. Beta 5000 applies at the element's stated rating.
Formats and fittings
Standard elements are 64 to 70 mm in diameter with DOE and SOE 222 or 226 fittings; CPU elements use Code-T stud nut, internal thread or 222 fin; HF elements are 6 inch outer diameter for large-format housings. Send your housing make and model and we confirm the fitting and O-ring.
Pleated cartridges: direct answers
When does a pleated cartridge beat a depth cartridge?
When efficiency at a fine rating, long service life, or membrane-grade media is the requirement. Pleating packs a large media area into the same 2.5 inch envelope, so the element loads slower and runs longer at low pressure drop. For heavy bulk solids ahead of it, a depth cartridge or bag filter is the better first stage; most well-designed trains use both.
Which Clarypleat media do I need?
PP for general aqueous and chemical duty. PES for sterile aqueous applications. PTFE for aggressive solvents, gases, and high temperature. PVDF for sterilizing-grade duty with broad compatibility. Nylon 66 where chemical compatibility with specific solvents matters. Send the fluid and the target rating; we confirm media and variant against the compatibility data.
Are Clarypleat cartridges suitable for pharmaceutical use?
The range is built with pre-washed, thermally welded construction, and membrane variants cover sterile-adjacent aqueous and solvent duty. For any regulated application, tell us the process stage and required documentation and we will confirm exactly what we can certify for that variant before you order, in line with our accuracy-over-impressiveness rule.
What sizes are available?
Standard lengths 10 to 70 inch in standard and jumbo diameters, with an engineered high-strength polypropylene core. High-flow duties are covered by Clarypleat HF and the high flow family with retrofit-compatible formats.
What does beta 5000 mean on Clarypleat 5000?
At the stated rating, only one particle in 5,000 passes the element, which is 99.98% removal efficiency. Clarypleat 5000 uses pleated glass fibre media, thermally welded without additives, rated to 80 C and 2.5 bar differential pressure.
How many sterilisation cycles do the membrane grades take?
The data sheets state, for example, 30 autoclave cycles of 30 minutes at 124 C for PVDF and PES, and 100 cycles of 60 minutes at 126 C for PTFE, with matching steam-in-place cycles at a stated maximum differential pressure. The membrane table on this page lists each grade. Qualify the element on your own cycle before regulated use.
When do I need a thick media element like Clarypleat TMP?
When gels or agglomerates blind thin media early. TMP uses much thicker non-woven polypropylene, so it filters both at the surface and in depth, and is used in beverages, pharmaceuticals and ink production.
What are capsule filters for?
Laboratory, pilot and small-scale filtration of liquids and gases where a sealed, disposable unit saves a housing and cleaning. PES, PTFE, PP and nylon capsules cover aqueous, solvent, gas and vent duty.
How much flow does a Clarypleat HF element take?
Suggested water flows in ideal conditions are 660 lpm for a 20 inch element, 1300 lpm for 40 inch and 1900 lpm for 60 inch, all at 6 inch outer diameter. Real sizing depends on the fluid, the solids load and the change-out interval you want.
What we need from you for a firm recommendation
- The fluid, temperature and chemistry
- The rating and efficiency you need, and whether the duty is sterile or sterile-adjacent
- Flow rate and what sits upstream to take bulk solids
- Housing make and model, length and fitting
- Sterilisation method and cycle, and the documentation your QA team needs
What the data sheets state
Membrane grades carry published safety and sterilisation data: bacterial endotoxin of 0.25 EU/mL or less, extractables of 15 to 40 mg per 10 inch by media, and stated autoclave and steam-in-place cycle counts. Clarypleat 5000 is rated at a beta ratio of 5000, which is 99.98% removal at the stated rating. PTFE cartridges are stated as manufactured, tested and packed in a clean room; capsule filters are stated as fully integrity tested, the PES capsules as made in a class 1000 facility. Ask for the data sheet and certificate of each variant before you qualify it; for regulated duty we confirm in writing what we can certify.
Chasing efficiency or service life? Usually it is both.
Send the fluid, the rating you need, and your current element's life. We will quote the Clarypleat variant and predict the change-out interval before you buy.
