DI resin filter fit our system. **Q: How many Gallons per hour?** A: For Ro system, Different temperature,different water pressure and feed water quality, the product water capacity and pure water quality is different. That is reason we feel low pure water capacity in the winter, but higher in the summer. Lab test condition : feed water pressure: 70 psi. work temperature: 77 F or 25 C. Nacl concentration: 250 ppm. recovery: 15%. For this system, capacity is 100 gallons per 24 hours. that is about 4.2 gallons pure water per hour if above work condition. Please refer. **Q: What does this system need to run? What does it hookup to?** A: FEED WATER PRESSURE:40 - 100 PSI (If less 40 psi, we must to add booster pump ,or else, system can not work); 60psi is best work pressure. if too less, pure water capacity will be less.
