Ultro Series High Flow Filter Cartridges
6 inch high flow pleated cartridges in 40 inch length, 1 to 70 micron, 500 gpm. Dimensional equivalent to 3M CUNO Ultro series.
What The Ultro Series High Flow Does In Your Line
Ultro Series is a 6 inch large diameter high flow cartridge with a radial pleated polypropylene pack, an inner core, and a support layer. It runs outside-in, so dirt is captured on the outside of the pleat pack and stays there during change-out. One 6 inch element replaces multiple smaller cartridges, which is why plants fit it when the existing filter skid has run out of space. It is dimensionally equivalent to the 3M CUNO Ultro series and drops into those housings without adapters.

Why Buyers Pick This Element
- One 6 inch element does the work of multiple smaller cartridges and frees skid footprint
- Radial pleat technology maximises effective filtration area per element
- Outside-in flow path keeps captured solids on the cartridge when an operator lifts it out
- High flow capacity up to 500gpm per cartridge reduces the number of elements needed
- Dimensional equivalent to the installed 3M CUNO Ultro series so no piping or housing change is needed
- Pleated type design with full length media pack reduces risk of media shedding
Buyers Who Specify This Cartridge
- Water treatment plant engineers replacing 3M CUNO Ultro high flow cartridges on an existing skid
- RO system integrators specifying prefiltration for new desalination or process water trains
- Pharmaceutical and electronics plant maintenance teams standardising on one cartridge across lines
- Filtration distributors who need an equivalent series to quote against 3M CUNO part numbers
What It Fixes On The Line
- Cartridge change-out on a large skid takes hours because there are too many small elements
- OEM high flow cartridges 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
- Radial pleated construction that maximises effective filtration area per element
- Single piece full length media pack with no joints along the cartridge
- Inner core and support layer for differential pressure strength
- Outside-in flow path for contaminant retention during change-out
- Round double O-ring adapter to match the installed housing seat
- Absolute micron ratings from 1 to 70 micron across the same body
Materials Of Construction
- Polypropylene filtration media, thermally bonded without adhesives or surfactants
- Polypropylene inner core and support layer for structural integrity
- Buna-N rubber O-rings for general water and industrial service
- Glass filled polypropylene end caps for rigidity and chemical resistance

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
- Flow rate verification at 500 gpm to confirm capacity
- O-ring compound and seating verification before packing
What We Can Change For You
- Lengths from 40 inch to match the installed housing

- O-ring compound chosen from Buna-N for general service
- Round double O-ring adapter to match the existing seat
- Private label printing and carton marking for distributors
How It Compares With The Alternatives
| 6 inch pleated cartridges | Ultro cuts element count and change-out labour, but the initial cartridge cost per piece is higher |
|---|---|
| 3M CUNO Ultro series | Same dimensions and fit at a lower landed cost and shorter lead time, without the OEM warranty documentation |
| Bag filters | Ultro holds a tighter absolute rating and does not bypass at the seal, but a bag is cheaper for coarse duty |
| Standard 6 inch pleated cartridges | Ultro uses radial pleat technology, which increases effective area and flow capacity compared to conventional pleat designs |
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 500 gpm differential rather than waiting for the maximum flow rate
- Do not exceed the maximum operating temperature; select a different O-ring 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
