SPP Series Depth Pleated Filter Cartridges
68 mm depth pleated filter cartridges in 20”, 30”, 40” lengths, 0.1 to 10 micron, 80℃, 4 bar. Dimensional equivalent to common OEM series.
What The SPP Series Depth Pleated Does In Your Line
SPP series depth pleated filter cartridges are constructed with a single piece full length polypropylene media pack, an inner core and an injection moulded outer cage. They are designed for outside-in flow, so captured solids remain on the cartridge surface during change-out. The cartridge body is dimensionally equivalent to common OEM series, allowing direct replacement in existing housings without adapters. It is built for continuous duty in water, process fluids and chemical applications with a maximum temperature of 80℃ and a maximum differential pressure of 4 bar at 21℃.

Why Buyers Pick This Element
- Single piece full length media pack eliminates joints and reduces leak risk
- Outside-in flow retains captured solids during change-out
- Dimensional equivalent to common OEM series for drop-in replacement
- Polypropylene construction resists water, solvents and mild chemicals
- Maximum differential pressure of 4 bar at 21℃ and 2.4 bar at 80℃
- Available in 20”, 30”, and 40” lengths to match existing housing configurations
Buyers Who Specify This Cartridge
- Plant engineers replacing OEM depth pleated cartridges in existing filter housings
- Procurement teams seeking lower cost alternatives to branded cartridges
- System integrators specifying replacement cartridges for new or retrofitted skids
- Filtration distributors who need to quote against OEM part numbers
What It Fixes On The Line
- OEM cartridges have long lead times and high unit cost per replacement cycle
- Jointed media packs in older designs can leak under differential pressure
- Solids fall off the cartridge during change-out and contaminate downstream systems
- Existing housings are full and there is no space to add more elements
- Plants need a cartridge that fits without modifying the housing or piping
Construction Detail

SPP Series Depth Pleated Filter Cartridges In Detail
Where It Is Installed
RO pretreatment in process water systems where particulate must be removed before membrane stages
Chemical processing lines where solvent resistance and temperature stability are required
Food and beverage applications with water-based fluids and moderate temperature
Pharmaceutical process water polishing where leak-free integrity is critical
Industrial water filtration where high dirt holding capacity and long service life are needed
How This Cartridge Is Built
Media Preparation
Media extrusion and pleating to a fixed pleat pitch
Pack Forming

Checks Before It Ships
- Dimensional check of outer diameter, length and adapter against the ordered code
- Pleat pack inspection for collapse, gaps and end cap bond integrity
- Differential pressure check against the 4 bar at 21℃ rating
- O-ring compound and seating verification before packing
What We Can Change For You
- Lengths from 20” to 40” to match the installed housing
- Micron rating selected from 0.1, 0.2, 0.45, 1, 5, 10 micron
- O-ring compound chosen from Buna, Silicone, EPDM or Viton
- Adapter selected from DOE, 226/flat, 222/flat, 226/fin, 222/fin to match the housing seat
- Private label printing and carton marking available for distributors
How It Compares With The Alternatives
| OEM branded depth pleated cartridges | Same dimensions and fit at a lower landed cost and shorter lead time, without the OEM warranty documentation |
|---|---|
| Multi-element cartridge banks | SPP replaces multiple small elements in one unit, reducing change-out labour and housing footprint |
| String wound cartridges | SPP offers higher dirt holding capacity and more consistent depth filtration, but may cost more per unit |
| Membrane pleated cartridges | SPP is designed for depth filtration with higher flow and lower pressure drop, but does not provide absolute rating |
Installing And Running This Cartridge
- Confirm housing bore, seat type and cartridge length before ordering; the adapter code must match
- Start clean differential pressure logging from day one so change-out is data driven
- Change out at 4 bar differential rather than waiting for the maximum rating
- Do not exceed 80℃; select Viton O-rings if the duty runs warm or carries aggressive chemicals
- Flush the housing before fitting a new element so settled solids do not load it immediately
- Lift the element vertically and keep it upright so captured solids stay on the pleat pack
