Summary
Product identification
- Product: Pentek WS Series Water Softener Cartridges
- Description: Designed for optimal contact between water and resin surfaces to ensure maximum ion exchange. These cartridges deliver softened product water using a sodium-based, non-solvent rinsed softening resin. They feature an internal expansion pad to minimize channeling and a post-filter to eliminate bypass.
- Key Features:
- Available in a variety of sizes for multiple applications
- Sodium form resin
- Utilize single-use resin technologies for maximum life grains (CaCO₃) capacity
- Compatibility: For use in Pentek Slim Line®, Standard, and Big Blue® Series Filter Housings.
- Applications: Medical equipment, coffee and espresso appliances, low volume beverage and commercial food service machines, or any application desiring low hardness and scale deposits.
Operating limits
- Temperature Rating: 40-100°F (4.4-37.8°C)
- Capacity Range: 750 to 4,500 grains (as CaCO₃)
Feed water
- WARNING: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
Mechanical / hydraulic
- Materials of Construction:
- Filter Media: Cation, sodium-form resin, 20 x 40 mesh, R-SO₃-Na⁺
- Endcaps: Polypropylene
- Pre-Filter: Polypropylene
- Post-Filter: Polypropylene
- Gaskets: Buna-N®
