  1. Innovative Design for Efficient and Reliable Filtration Systems

  2. Self-Cleaning Screen Water Filters • Automatic • Low Wastewater • Continual Flow • Low Maintenance • High Efficiency • Dependable • Cost-effective • Point-of-Suction Backwash

  3. How it Works

  4. Stage 1: Clean Water flows through the coarse screen and fine screen. Suspended particles are trapped on the fine screen.

  5. Stage 2: Dirty Debris builds on the inside of the screen until 7 psid is reached on the differential pressure gauge.

  6. Stage 3: Backwash The flush valve opens, creating a low pressure path for the suction nozzles to vacuum the debris from the screen.

  7. Stage1: Clean Differential pressure drops back to below 1 psid. The clean filter continues normal operation uninterrupted.

  8. Advantages vs. Bag & Cartridge Filters • Automatic Backwash • No Replacing Cartridges • Less System Downtime • Less Time Spent on Routine Maintenance • No Waste from Disposable Bags and Cartridges

  9. Advantages vs. Sand Filters • Backwash does not Require Filter Bypass • Does not Require Parallel Configuration • Much Less Water Used for Backwash • Durable Stainless Steel Design • Predictable Solid Filtration Barrier

  10. Advantages vs. Centrifugal Filters • Predictable Solid Filtration Barrier • Does not Require a Minimum Velocity • Removes ALL Solids, Regardless of Density

  11. Advantages vs. Disc Filters • Static Filtration Barrier • Much Higher Flow Rates • Robust MOC • No Need to Manifold Many Units in Parallel
