ATS Water Technology offers the SAF self-cleaning filter that provides high filtration efficiency with robust and simple construction and Amiad’s proven suction-scanning cleaning technology.
The reliable operating mechanism and simple construction make it the ideal solution for filtration of poor industrial water quality to very fine filtration degrees.

  • Technology: Screen
  • Type: Automatic
  • Filtration degree: 10 - 800  micron
  • Flowrates: up to 400 m3/h 

The SAF filter offers a large filtration area and suction scanner cleaning technology driven by an electrical drive-unit.
Suitable for a wide variety of industrial water filtration applications, heavy loads, and challenging types of TSS.
Automatic cleaning without flow interruption and with minimal wastewater.
The SAF Series includes four models with various sizes and flange connections and the filters are adaptable to special applications and specific requirements.


  • Large filter area, reliable operating mechanism and simple construction make the SAF filters the ideal solution for filtration of poor water quality to very fine filtration
  • Automatic self-cleaning according to pressure differential and/or time
  • No interruption of downstream flow during self-cleaning •Robust and reliable self-cleaning mechanism, even in marginal operating conditions
  • Applications: municipal water supply systems, cooling water, wastewater treatment, industrial pre-filtration, membrane protection, irrigation systems, etc.
  • Industries: manufacturing, oil and gas, mining, water and wastewater treatment plant, turf and agriculture, etc.


The Amiad SAF filters are sophisticated, yet easy-to-operate, automatic filters, with a self-cleaning mechanism driven by an electric motor.
The “SAF” filters support flow rates of up to 400 m³/h (1,760 GPM), with various screens designed to cover a range of filtration degrees, from 20 to 800 micron, and are available in inlet/outlet diameters of 2” to 10”.


Raw water enters the filter inlet (1) through the coarse screen (2) which protects the cleaning mechanism from large debris. The water passes through the fine screen (3), trapping dirt particles that accumulate inside the filter. Clean water flows through the filter outlet (4). The gradual dirt buildup on the inner screen surface causes a filter cake to develop, with a corresponding increase in the pressure differential across the screen. A pressure differential switch senses the increased pressure differential and when it reaches a pre-set value (typically 7.0 psi), the cleaning process begins.

Cleaning of the filter is carried out by the suction scanner (5) which spirals across the screen. The open exhaust valve creates a high-velocity suction stream at the nozzles tip which “vacuums” the filter cake from the screen. During the self-cleaning process, which takes between 15 to 40 seconds, filtered water continues to flow downstream.


Operation and monitoring is done by PLC (Programmable Logic Controller). The PLC allows maximum operation flexibility and provides a wide range of control options from an independent stand-alone unit up to full integration within the customer’s central control system.


1. Flushing by pressure differential – DP analog or digital signal
2. Flushing by time intervals
3. Continuous flushing – regardless of DP or time
4. Remote or local manual start


• Flush cycle counter
• Cause of flushing statistics
• Faults and alarms, reaction and messages
