PP Melt Blown Sediment Filter Cartridges
2.5 inch and 4.5 inch polypropylene melt blown cartridges in 5 to 70 inch lengths, 0.5 to 100 μm, 35 psid. Dimensional equivalent to common OEM series
What The PP Melt Blown Sediment Does In Your Line
PP Melt Blown is a depth filter cartridge with a polypropylene melt blown media pack, an inner core, and thermally bonded end caps. It runs outside-in, so particulates are captured throughout the media thickness and remain trapped during change-out. The cartridge is dimensionally equivalent to common OEM series and fits into standard housings without adapters. Available in 2.5 inch and 4.5 inch diameters and lengths from 5 inch to 70 inch, it is used in prefiltration and polishing applications across multiple industries.

Why Buyers Pick This Element
- Outside-in flow path captures and retains solids within the media during change-out
- Polypropylene construction resists chemical attack and contaminant unloading under pressure
- Grooved exterior increases effective filtration surface area
- Thermally bonded end caps eliminate adhesive or sealant contamination
- Multiple length and micron options allow direct replacement for OEM cartridges
- FDA listed materials make it suitable for food and beverage process lines
Buyers Who Specify This Cartridge
- Plant engineers replacing OEM melt blown cartridges in existing housings
- Procurement teams seeking lower-cost alternatives to branded cartridges
- Filtration distributors specifying drop-in replacements for common OEM part numbers
- System integrators designing prefiltration stages for new process skids
What It Fixes On The Line
- OEM melt blown cartridges carry long lead times and high unit cost
- Cartridge change-out is difficult when captured solids fall off during removal
- Pleated or membrane cartridges are too expensive for coarse sediment removal
- Adhesive or sealant in bonded end caps may leach into sensitive fluids
- Housings are full and no space exists for additional filtration elements
Construction Detail
- Melt blown polypropylene media with controlled fiber diameter and density
- Thermally bonded end caps with no adhesives or surfactants
- Grooved exterior to increase surface area and dirt holding capacity
- Outside-in flow path for deep media filtration and solid retention
- Available in 2.5 inch and 4.5 inch diameters with multiple length options
- End caps available in glued or thermally-bonded configurations
Materials Of Construction
- Polypropylene melt blown filtration media with uniform fiber density
- Polypropylene end caps thermally bonded without adhesives or surfactants
- Silicone O-rings for general water and low extractable applications
- Buna O-rings for hydrocarbon and general industrial water service
- Polydoam O-rings for moderate chemical and temperature resistance
- EPDM O-rings for water, hot water, and general chemical duty
- Viton O-rings for aggressive chemicals and higher temperature service

How This Cartridge Is Built
Media Preparation
Polypropylene melt blowing to form a uniform fiber matrix with controlled porosity
Pack Forming
Media forming to full cartridge length in a single piece
Hardware Assembly
Thermal bonding of end caps to the media pack without adhesive
End Cap Bonding
O-ring and adapter fitting to the ordered configuration
Configuration
Inspection for end cap bond integrity and media uniformity
Inspection And Packing
Flush, drain, and individual packing for shipment
Checks Before It Ships
- Dimensional check of outer diameter, length, and end cap alignment
- Visual inspection of media for voids, gaps, or uneven bonding
- Differential pressure test at 35 psid to verify structural integrity
- O-ring compound and seating verification before packing
- Final inspection of end cap bond and cartridge surface
What We Can Change For You
- Length selected from 5 inch to 70 inch to match installed housing
- Micron rating chosen from 0.5 μm to 100 μm for the required duty
- O-ring compound selected from Silicone, Buna, Polydoam, EPDM, or Viton
- End cap configuration specified as thermally bonded or glued
- Private label printing and carton marking available for distributors
How It Compares With The Alternatives
| Membrane pleated cartridges | PP Melt Blown offers higher dirt capacity and lower cost for coarse sediment, but does not provide absolute micron rating |
|---|---|
| String wound cartridges | PP Melt Blown has more consistent pore structure and better resistance to contaminant unloading, but may have lower capacity for very high solids loading |
| OEM branded melt blown cartridges | Same dimensions and fit at a lower landed cost and shorter lead time, without OEM warranty documentation |
| Activated carbon cartridges | PP Melt Blown removes particulates only; carbon cartridges remove organics and odors, but not particulates alone |
Installing And Running This Cartridge
- Confirm housing bore, seat type, and cartridge length before ordering
- Start differential pressure logging from day one to schedule change-outs
- Change out at 20 psid differential to avoid exceeding the 35 psid maximum
- Do not exceed 35 psid forward pressure; select Viton O-rings for aggressive fluids
- Flush the housing before installing a new element to prevent immediate loading
- Lift the cartridge vertically and keep it upright to prevent solids from falling off
