HFBH Bag Style High Flow Filter Cartridges
6 inch high flow pleated bag cartridges in 16” and 32” lengths, 1 to 100 micron, 80 ℃, 3.5 bar. Dimensional equivalent to #1 and #2 bag filter housing
What The HFBH Bag Style High Flow Does In Your Line
HFBH is a 6 inch diameter high flow pleated bag style cartridge with a polypropylene media pack, an inner core, and an injection moulded outer cage. It runs inside-out, so dirt is captured on the inside of the pleat pack and stays there during change-out. One HFBH element replaces a bank of standard bag filters, which is why plants fit it when the existing filter skid has run out of housing space. It is dimensionally equivalent to the common #1 and #2 bag filter housings and drops into those housings without adapters.

Why Buyers Pick This Element
- One 6 inch element does the work of a bank of standard bag filters and frees skid footprint
- Inside-out flow path keeps captured solids on the cartridge when an operator lifts it out
- Polypropylene media and cage provide wide chemical compatibility and high strength
- Graded density structure offers depth filtration for higher dirt holding capacity
- Injection moulded outer cage takes the differential pressure without pleat collapse
- Dimensional equivalent to the installed #1 and #2 bag filter housings so no piping or housing change is needed
Buyers Who Specify This Cartridge
- Water treatment plant engineers replacing OEM bag filters on an existing skid
- RO system integrators specifying prefiltration for new desalination or process water trains
- Chemical and paint plant maintenance teams standardising on one cartridge across lines
- Filtration distributors who need an equivalent series to quote against OEM part numbers
What It Fixes On The Line
- Bag filter change-out on a large skid takes hours because there are too many small elements
- OEM bag filters carry long lead times and high unit cost per replacement cycle
- Filter housings are full and there is no floor space to add another vessel for more flow
- Pleat packs collapse under differential pressure and shed captured solids back into the line
- Solids fall off the element during change-out and contaminate downstream filtrate
Construction Detail
- Inside-out flow path for contaminant retention during change-out
- Polypropylene media with graded density structure for depth filtration
- Single piece full length media pack with no joints along the cartridge
- Inner core plus injection moulded outer cage for differential pressure strength
- Round double O-ring adapter to match installed #1 and #2 bag filter housings
- Absolute micron ratings from 1 to 100 micron across the same body
Materials Of Construction
- Polypropylene filtration media, thermally bonded without adhesives or surfactants
- Polypropylene inner core and 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
RO pretreatment ahead of membrane racks in a desalination or demineralisation train
Chemical process filtration where aggressive fluids require high compatibility
Paint and coating line filtration to remove particulates before application
Oil and gas production water treatment where high flow and durability are critical
Bulk liquid transfer where particulate must be removed at high flow with low pressure drop
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 injection moulded cage assembly
End Cap Bonding
Thermal end cap bonding without adhesive
Configuration
O-ring and adapter fitting to the ordered configuration
Inspection And Packing
Flush, drain and individual packing
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 3.5 bar at 21 ℃ rating
- O-ring compound and seating verification before packing
What We Can Change For You
- Length combinations from 16 inch to 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
- Round double O-ring adapter to match the existing seat
- Private label printing and carton marking for distributors
How It Compares With The Alternatives
| Standard bag filters | HFBH holds a tighter absolute rating and does not bypass at the seal, but a standard bag is cheaper for coarse duty |
|---|---|
| OEM branded bag filters | Same dimensions and fit at a lower landed cost and shorter lead time, without the OEM warranty documentation |
| 6 inch pleated cartridges | HFBH uses a bag-style pleat geometry, which allows higher flow and depth filtration, but may not match the same micron rating range as a standard pleated cartridge |
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
