The Enpress ONE CT-5020-SWMB is the coarser of the two Yellow Filtration Series sediment cartridges for the Enpress ONE Cartridge Tank: a 50-micron string-wound outer filter of 100% polypropylene yarn over a 20-micron thermally bonded meltblown core. It is the cartridge for heavy sand, silt and scale loads, holding more dirt between changes than the 20 / 5 micron CT-2005-SWMB while still finishing at 20 micron.
Fits our NFS-HF Cartridge Tank Filtration System (residential / light-commercial configuration).

How it is built
- String-wound outer — 100% polypropylene yarn in a precision pattern that captures 50 micron and larger and protects the core.
- Meltblown inner core — thermally bonded polypropylene fibres rated 20 micron, with minimal pressure drop and no fibre shedding.
- Handle top cap for lightweight removal, and a double o-ring base that seats in the Cartridge Tank plumbing adapter — lift out, drop in, no tools.
- Supplied with a disposal bag.
Flush a new cartridge before use. Run water to drain until it runs clear before putting the system into service. Enpress recommends a drain on the outlet side of the Cartridge Tank for this.
Not a disinfection device. Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
Where it is used
First-stage sediment removal on dirty well water and process water with heavy sand, silt or scale, and as a roughing filter ahead of a finer cartridge. Where the load is lighter and you want a 5-micron finish, the CT-2005-SWMB is the better choice.
