The Enpress ONE CT-COMM20-MB is a Purple Filtration Series commercial cartridge for the Enpress ONE Cartridge Tank in its commercial configuration: a 20-micron meltblown polypropylene depth filter with the large surface area and extended life the series is built for. Depth media holds dirt through its whole thickness rather than on a surface, which is what makes meltblown the choice for heavier sediment loads at commercial flow.
Fits our NFS-HF-PLUS Commercial Cartridge Tank System (commercial 4.5" configuration).

How it is built
- Meltblown polypropylene depth media — graded fibre structure that loads dirt through its thickness for long life at 20 micron.
- Polypropylene body and cap — durable and chemical resistant.
- Double EPDM o-rings — the commercial seal specification for this series.
- 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
Commercial and industrial sediment removal at up to 100 gpm where a depth filter suits the load better than a pleat: make-up water, process water, cooling and pre-filtration. Fits the commercial 4.5" configuration of the Cartridge Tank (NFS-HF-PLUS), not the residential one.
