Netafim Arkal 150mm Semi Automatic Twin Check Screen Filters with 2500cm² Filtration Area

Arkal’s all-polymeric corrosion-resistant semi-automatic industrial water filters allow for simple manual cleaning of the filter screen without removing the screen itself. They have high mechanical strength and durability, and require less maintenance, saving time and money. The semi-automatic filters offer a large filtration area for maximum efficiency, and the downstream flow is not interrupted during self-cleaning. A variety of filtration degrees are available for applications including Industrial water filtration.

Quick and easy manual cleaning. Scan-Kleen Screen Filters offer quick and easy manual cleaning without flow interruption. To clean, just open the flush valve and turn the handle to rotate the dirt collector. The combination of rotation and linear movement scans and cleans the whole internal screen surface. Water flow is not interrupted during the cleaning process. A stainless steel screen provides strength and long life durability.

The stainless steel screen provides strength and long life durability and is ideal for use as a primary filter on well water with small amounts of sand or reservoir water with small amounts of algae. When cleaning the filter, there is no need to manually disassemble, clean the screen and reassemble the filter. Just open the flush valve and turn the handle to rotate the dirt collector. The combination of rotation and linear movement scans and cleans the while internal screen surface. Water flow is not interrupted during the cleaning process.

FLUSHING OPERATION

Water enters the filter through the inlet and reaches the screen which traps the particles from the water. As more water flows through, debris builds up on the screen. As debris accumulates on the screen, a pressure differential builds up between the internal and external sections of the screen.

When the pressure differential reaches the determined value (7-10 psi), the filter should be cleaned. Water continues to flow through the filter during the cleaning process.

• Opening the flushing valve (4) allows water to flow out of the filter
• Suction occurs through the nozzles (6) which vacuums the debris from the screen (1) and out the drain port
• Turning the handle (3) slowly rotates the dirt collector (2) resulting in full scanning of the screen by the nozzles. Slower rotation cleans the screen more efficiently.

This combination of rotation and linear movement cleans the whole internal screen surface. The flushing cycle takes about 10 seconds.
