AZUD LUXON LDB
Azud Industrial Filtration
Automatic electric screen filters suitable for all applications and available in a wide range of micron sizes, all with the same high quality guarantee of AZUD.
Max. flow: 1065 m³/h (4690 gpm).
The consumption of water in the flushing cycle is minimal.
Wide selection of screens
From 10 to 1.000 micron.
From 2″ to 16″.
Tempertures to 60ºC.
Large screen area
Up to 21.300 cm2.
The screen is manufactured in high quality stainless steel.
The filtration process and the flushing cycle occur simultaneously.
The filters are delivered to be installed.
Raw water enters from the inlet manifold to the coarse screen,trapping larger particles that could interfere with the filter cleaning mechanism -in vertical models, large and heavy particles are separated by gravity.
Then water flows IN-OUT through the weave wire screen, trapping in the inner screen surface bigger particles than the filtration degree. Clean water flows out through the outlet manifold . Particles build-up creates a filter cake that increases the pressure differential between inlet and outlet, and this activates the cleaning cycle when the pre-set point is reached.
Clean water supply is not interrupted when the cleaning cycle is activated. The cleaning phase starts with the opening of the drain valve, that creates a pressure gradient between the pressurized inner filter and the atmosphere. At the same time, the suction nozzle scanner spirals along the complete inner surface of the screen.
As a result of the pressure difference, a high velocity Suction Effect is created at the inlet of the nozzles, making the water flows OUT- IN through the filter element and vacuuming all the particles retained on the screen surface.
