Pleated Bag High Flow Filter Cartridges
6 inch pleated bag high flow cartridges in 16 and 32 inch lengths, 1 to 100 micron, 80 ℃, 3.5 bar. Dimensional equivalent to #1 and #2 bag filter hous
What The Pleated Bag High Flow Does In Your Line
HFBH is a 6 inch diameter high flow pleated bag cartridge with a polypropylene and glass fiber media pack, an inner core, and a rigid polypropylene outer cage. It runs inside-out, so dirt is captured on the inside of the pleat pack and remains there during change-out. One HFBH element replaces a standard #1 or #2 bag filter, which is why plants use it when upgrading from disposable bags to reusable cartridges. It is dimensionally equivalent to the standard #1 and #2 bag filter housings and drops into those housings without adapters.

Why Buyers Pick This Element
- One HFBH element replaces a standard bag filter, reducing change-out frequency and waste
- Inside-out flow pattern retains captured solids during change-out, preventing downstream contamination
- 3 times longer service life than standard filter bags under similar duty
- Rigid polypropylene outer cage maintains structural integrity under differential pressure
- Polypropylene and glass fiber media pack provides high filtration efficiency across multiple micron ratings
- Dimensional equivalent to standard #1 and #2 bag filter housings, so no housing modification is needed
Buyers Who Specify This Cartridge
- Plant engineers upgrading from disposable bag filters to reusable high flow cartridges
- Procurement teams seeking lower long-term cost per filtration cycle without changing housing
- System integrators specifying durable, high-efficiency pre-filters for new skids
- Filtration distributors who need a drop-in replacement for standard bag housing applications
What It Fixes On The Line
- Standard bag filters tear or rupture during change-out, releasing captured solids into the line
- Frequent bag changes increase labour, downtime and waste disposal costs
- Bag filters have limited service life and cannot handle high flow with low pressure drop
- Existing bag housings are full and cannot accommodate additional filters without modification
- Solids fall off the bag during removal and contaminate the filtrate or downstream process
Construction Detail
- Inside-out flow path captures contaminants on the inner surface of the pleat pack
- Single piece full length media pack with no joints or seams along the length
- Rigid polypropylene outer cage resists deformation under differential pressure
- Polypropylene inner core and end caps provide chemical resistance and structural support
- Available in 16 inch and 32 inch lengths to match standard #1 and #2 bag housing dimensions
- Absolute micron ratings from 1 to 100 micron across the same cartridge body
Materials Of Construction
- Polypropylene and glass fiber filtration media, thermally bonded without adhesives or surfactants
- Polypropylene inner core and rigid injection moulded outer cage
- EPDM O-rings for general water and hot water service
- Buna O-rings for hydrocarbon and general industrial water
- Silicone O-rings where a low extractable elastomer is preferred

Where It Is Installed
Oil and gas process lines where particulate must be removed before downstream equipment
Chemical transfer systems requiring consistent filtration without bag rupture or bypass
Paint manufacturing where fine particles affect product quality and coating performance
RO pretreatment stages where high flow and long service life reduce downtime and cost
Industrial water treatment where bag filters are replaced with more durable cartridge solutions
How This Cartridge Is Built
Media Preparation
Media extrusion and pleating to a fixed pleat pitch
Pack Forming
Vertical pleat pack forming to full cartridge length in one piece
Hardware Assembly
Core insertion and rigid polypropylene cage assembly
End Cap Bonding
Thermal end cap bonding without adhesive
Configuration
O-ring and end cap fitting to the ordered configuration
Inspection And Packing
Flush, drain and individual packing
Checks Before It Ships
- Dimensional check of outer diameter, inner diameter, length and adapter against the ordered code
- Pleat pack inspection for collapse, gaps and end cap bond integrity
- Differential pressure check against the 3.5 bar at 21 ℃ rating
- O-ring compound and seating verification before packing
What We Can Change For You
- Length selected from 16 inch or 32 inch to match the installed housing
- Micron rating selected from 1 to 100 micron for the duty
- O-ring compound chosen from EPDM, Buna or Silicone
- End cap and adapter configuration matched to the existing housing seat
- Private label printing and carton marking for distributors
How It Compares With The Alternatives
| Standard #1 and #2 bag filters | HFBH has 3 times longer service life and inside-out flow prevents solids release during change-out, but the initial cartridge cost is higher |
|---|---|
| Standard pleated cartridges | HFBH uses a pleated bag geometry with higher dirt holding capacity and is designed for bag housings, while standard pleated cartridges may not fit the same housing |
| Disposable filter bags | HFBH is reusable and reduces waste and change-out frequency, but requires a one-time investment in the cartridge body |
| OEM branded bag filters | Same dimensions and fit at a lower landed cost and shorter lead time, without the OEM warranty documentation |
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 2.4 bar differential rather than waiting for the 3.5 bar maximum
- Do not exceed 80 ℃; select Viton O-rings if the duty runs warm or carries solvents
- 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
