AXEON FST and FSD Series — Single and Multi-Stage Cartridge Filtration
A pressure vessel containing replaceable filter cartridges inline within water treatment systems. The housing maintains system pressure, directs flow through the cartridge media, and enables cartridge replacement without disconnecting pipes.
FST Series
- Single cartridge housing, 10" and 20" lengths
- Maximum rated flow: 15 GPM
FSD Series
- Housing: Polypropylene construction
- Connections: 3/4" or 1" FNPT
- Pressure range: 45–85 PSI maximum
- Temperature: 40°F to 100°F
- Maximum flow: 30 GPM
10-inch cartridges offer lower media volume and shorter service intervals; 20-inch versions provide greater media area, generally lower pressure drop, and extended service life under equivalent contamination loads.
Opt for FSD configurations when peak flow exceeds 15 GPM, multi-stage filtration sequences are required, or the design calls for defined staged layouts from inception.
Frequently Asked Questions
What is the maximum flow rate for an AXEON FST housing?
The FST Series is rated to 15 GPM maximum in a single cartridge housing (10" or 20" lengths). For higher flow, the multi-stage FSD Series scales to 30 GPM.
When should I choose FSD over FST cartridge housings?
Specify FSD configurations when peak flow exceeds 15 GPM, when the application requires multi-stage filtration in sequence, or when the design calls for defined single-, dual-, or triple-stage layouts from the start.
Should I use a 10-inch or 20-inch filter cartridge?
10-inch cartridges have lower media volume and shorter service intervals. 20-inch cartridges provide more media area, generally lower pressure drop, and longer service life under the same contamination load.
What is the pressure and temperature rating of the FSD Series?
FSD housings are polypropylene construction rated 45–85 PSI maximum and 40°F to 100°F, with 3/4" or 1" FNPT connections.
