Advanced Industrial Water Filtration Solutions
At Purecowater, we specialize in providing top-tier engineered solutions for complex liquid filtration challenges. As a distributor for industry-leading manufacturers, we are proud to offer the Amiad SAF Series—specifically the next-generation SAF-X Series. These automatic self-cleaning filters are designed to handle heavy suspended solid loads and varying water qualities, making them a staple in industrial water treatment.
What is the Amiad SAF Series?
The Amiad SAF (and the evolved SAF-X) Series represents a line of sophisticated automatic screen filters. They utilize suction-scanning technology to remove organic and inorganic suspended solids from water. Unlike manual filters that require downtime for cleaning, the SAF Series continues to supply filtered water downstream even during its cleaning cycle.
The SAF-X Series improves upon the original SAF design with simpler maintenance mechanisms, a larger filtration area, and greater installation flexibility. It is specifically engineered to operate efficiently even in harsh conditions with high Total Suspended Solids (TSS).
Key Technologies
- Suction-Scanning Cleaning: A focused cleaning mechanism that uses less than 1% of the total process water.
- Uninterrupted Flow: The system does not stop filtration during the backwash cycle.
- Large Filtration Area: Incorporates advanced multi-layer weave wire mesh to handle high flow rates and loads.
How the Self-Cleaning Mechanism Works
The efficiency of the SAF Series lies in its “cleaning on demand” capability. The process is fully automatic and triggered by a pressure differential or a timer.
- Filtration: Raw water enters the filter inlet and passes through a coarse screen (to catch large debris) and then a fine screen. Clean water exits the outlet.
- Cake Buildup: As particulates accumulate on the inner surface of the fine screen, a “filter cake” forms, causing a pressure differential across the screen.
- The Cleaning Cycle: Once the pressure differential reaches a preset value (typically 7 psi or 0.5 bar), the self-cleaning cycle begins.
- The exhaust valve opens to the atmosphere.
- A suction scanner with nozzles spirals across the inner screen surface.
- The pressure difference between the water inside the filter and the atmosphere outside creates a powerful suction force at the nozzle tips.
- This vacuum effect sucks the dirt cake off the screen and discharges it out the exhaust valve.

Common Applications
Due to their robust design and ability to handle poor water quality, Amiad SAF filters are utilized across various sectors:
- Wastewater Treatment: Polishing effluent before discharge or reuse.
- Cooling Towers: Side-stream filtration to remove particulates and improve thermal efficiency.
- Pre-Filtration: Protecting Membrane (RO/UF) systems and other sensitive downstream equipment from fouling.
- Industrial Process Water: Protection of nozzles, pumps, and heat exchangers.
- Desalination: Intake water filtration.
Why Choose the SAF Series?
The SAF-X Series stands out for its reliability and simplicity. The hinged lid allows for easy access during maintenance, and the instrumentation can be installed on either side of the filter, providing flexibility in tight piping galleries. Furthermore, the electronic controller allows for integration with modern plant control systems, providing data on flushing frequency and pressure differentials.
If you are dealing with high TSS loads or need a reliable pre-filtration solution for your facility, the Amiad SAF Series is a proven choice.
