Semi-automatic screen filter, 4 inches

Description

The automatic self cleaning screen filter can be used for mechanical filtration, both industrial and irrigation systems.

130 filtration degree – recommended for the protection of pipes, pumps, irrigation systems.

Other filtration degrees – recommended for industries based on the consumers’ needs.

Most frequently used filtration degrees are 30, 50, 100, 130 and 200, but we can provide you with cartridges anywhere between 30 and 2000 microns.

Screen cartridge – recommended for wheel / drill water. Commonly used to remove sand.

Applications:

• Factories – processed water, water for food & beverage, bottled water (along with other equipment).
• Residential and commercial buildings; logistics halls.
• 1st or 2nd stage placed before other filtration systems, depending on the needs.
• Irrigations – agriculture, viticulture.

Working principle

The water flows through the inlet and reaches to the fine screen (1) which is covered and protected by a coarse screen (3) made of rough material. Here, the dirt particles are trapped inside the fine screen while the filtered water flows through the outlet. (2) Trapped dirt particles from the filter cake on the inner surface of the fine screen. In order to clean the filter, open the drainage valve to allow the trapped particles to be flushed away from the system. After, rotating the handle (5) in counter clockwise direction and then clockwise rotation. In this way, the suction nozzles (4) move in a spiral movement along the screen to vacuum up the collected dirt particles from the screen. The captured particles are flushed out the drain. (6) Repeat this process until the inlet and outlet pressures are balanced. Cleaning is done during the filtration process without interrupting the water flow through the filter.

Other information:

• Drain for purged water is required.
• There is no need to replace the cartridge.
