COMPATIBILITY & APPLICATIONS

Ideal Use Cases

The TW30-2521 membrane is designed specifically for small commercial reverse osmosis systems processing municipal tap water or well water with low to moderate TDS levels. Common applications include coffee shops, restaurants, small-scale beverage production, laboratories, medical offices, and aquarium systems requiring high-purity water at flow rates under 1 GPM. This membrane fits standard 2.5-inch housings and integrates seamlessly with Filmtec-compatible commercial RO systems. The compact 21-inch length makes it suitable for space-constrained installations while maintaining the proven performance and longevity Dow Filmtec membranes are known for across commercial water treatment industries.

💧 Individual membrane elements may vary ±20% from nominal flow rates due to manufacturing tolerances. Always size your RO system based on conservative flow estimates, and note that Filmtec periodically updates specifications for product improvement—verify current data sheets for critical applications.
