Filtration

Water enters the filter through the “Inlet” [7]. The water then reaches the fine screen [6], which purifies the flow by separating smaller particles from the water. As more water flows through, impurities build up on the fine screen.

As impurities on the screen accumulate, a pressure imbalance is built up between the internal section of the fine screen [6] and its external section.

 

Cleaning Process 

When the difference in pressure [ΔP] reaches the preset value on the differential pressure indicator [11], a series of events is triggered while water continues to flow to the system units. The controller transmits a signal for a 15 second flushing cycle. The flushing valve [3] opens, pressure is released from the hydraulic piston [1] and water flows outside. Pressure in the hydraulic chamber [4] and the dirt collector [2] is significantly lowered resulting in a suction process via the suction nozzles [8] to the dirt collector [2] and from there to the hydraulic chamber [4] through the flushing valve [3] outside. The electric motor [12] simultaneously rotates the dirt collector [2] around its axis. The pressure is released from the piston [1] and the high pressure inside the filter causes vertical movement of the dirt collector. The combination of the vertical movement and rotation efficiently cleans the entire internal screen [6] surface.

 

At the end of the 15 second cycle the flushing valve [3] closes and the operation of the electric motor [12] is stopped. The increased water pressure returns the hydraulic piston [1] to its initial position. The filter is now ready for the next cycle, with clean and filtered water flowing through the “Outlet” [5].

 

The 15 second flushing cycle resumes operation whenever the difference in pressure reaches the preset pressure value set on the differential pressure indicator. If the pressure difference remains unchanged after one cycle, another cycle will start after a delay of 15 seconds.

Operation Information for AF-900 Series Electric Self-Cleaning Filter

 

Filtration

Water enters the filter through an “Inlet” [6] and passes through the coarse screen [7] that functions as a “first stop” for rough particles.  Water then reaches the fine screen [8], which further purifies the flow by separating smaller particles from the water. As more water flows through, impurities build up on the fine screen. As impurities on the screen accumulate, a pressure imbalance is built up between the internal section of the fine screen [8] and its external section.

 

Cleaning Process 

When the difference in pressure [DP] reaches the preset value on the differential pressure indicator, a series of events is triggered while water continues to flow to the system units. The flushing valve [3] opens, and water flows outside.  Pressure in the hydraulic flushing chamber and the dirt collector [5] is significantly lowered resulting in a suction process via the suction nozzles [4] to the dirt collector [5] and from there through the flushing valve [3] outside. The electric motor [1] simultaneously rotates the dirt collector [5] and moves it along its axis. The combination of the linear movement and rotation efficiently cleans the entire internal screen [8] surface.

 

The flushing cycle continues as long as the pressure difference between the inlet and outlet remains the same and according to signals from the controller. If the pressure difference remains unchanged for a fixed preset time, the emergency flushing valve [2] opens along with the normal flushing valve [3].

 

The flushing cycle continues for the time that was preset on the controller. The flushing valves [2] & (3) close when the pressure difference on the pressostat drops. The operation of the electric motor is stopped after the collector axis reaches the internal or external limit switches. The filter is now ready for the next cycle, with clean and filtered water flowing through the “Outlet” [9].

Filtration

Water enters the filter through the “Inlet” [10] and passes through the coarse screen [2] that functions as a “first stop” for rough particles.  Water then reaches the fine screen [9], which further purifies the flow by separating smaller particles from the water.  As more water flows through, impurities build up on the fine screen. As impurities on the screen accumulate, a pressure imbalance is built up between the internal section of the fine screen [9] and its external section.

 

Operation information for model AF-9800-C

The process is the same as the above however there is no pre-filtration with a coarse screen [2] as the filtration grade is 400 - 3000 micron.

 

Cleaning Process

When the difference in pressure [ΔP] reaches the preset value on the differential pressure indicator, Or when the preset time in the controller arrives, a series of events is triggered while water continues to flow to the system units.  The controller transmits a signal for a 15 second flushing cycle. The solenoid opens the flushing valve [5] and release the pressure from the hydraulic piston [7].  Water flows outside from the flushing valve [5].  Pressure in the hydraulic chamber [6] and the dirt collector [3] is significantly lowered resulting in a suction process via the suction nozzles [4] to the dirt collector [3] and from there to the hydraulic chamber [6] through the flushing valve [5] outside. The electric motor [1] simultaneously rotates the dirt collector [3] around its axis. The pressure is released from the piston [7] and the high pressure inside the filter causes linear movement of the dirt collector. The combination of the linear movement and rotation efficiently cleans the entire internal screen [9] surface.

 

At the end of the 15 second cycle the flushing valve [5] closes and the operation of the electric motor [1] is stopped. The increased water pressure returns the hydraulic piston [7] to its initial position. The filter is now ready for the next cycle, with clean and filtered water flowing through the “Outlet” [8].

 

The 15 second flushing cycle resumes operation whenever the difference in pressure reaches the preset pressure value set on the differential pressure indicator. If the pressure difference remains unchanged after one cycle, another cycle will start after a delay of 10 seconds.

Filtration

Water enters the filter through the “Inlet” [4] and passes through the fine screen [3], which purifies the flow by separating smaller particles from the water.  As more water flows through, impurities build up on the fine screen. As impurities on the screen accumulate, a pressure imbalance is built up between the internal section of the fine screen [3] and its external section.

 

Cleaning Process

When the difference in pressure [ΔP] reaches the preset value on the differential pressure indicator, or the duel time between flushing passed, series of events is triggered while water continues to flow to the system units.  The controller transmits a signal for a 10 second flushing cycle. The flushing valve [5] opens, pressure is released from the inner side of the fine screen [3] the electric motor [1] simultaneously rotates the brushes [2] around its axis. The brushes wipe all the dirt and efficiently clean the entire internal screen [3] surface.

 

At the end of the 10 second cycle the flushing valve [5] closes and the operation of the electric motor [1] is stopped. The filter is now ready for the next cycle, with clean and filtered water flowing through the “Outlet” [6].

 

The 10 second flushing cycle resumes operation whenever the difference in pressure reaches the preset pressure value set on the differential pressure indicator. If the pressure difference remains unchanged after one cycle, another cycle will start after a delay of 10 seconds.
