Automatic hydraulic screen filters suitable for all applications and available in a wide rangeof micron sizes, all with the same high quality guarantee of AZUD.
RELIABLE FILTRATION in a wide range of
filtration degrees (50-1000 micron), thanks to arobust stainless steel screen housed in a steelvessel.EFFICIENT SELF-CLEANING with no interruption
of clean water supply. The exclusive AZUD suction nozzles provides high suction capacity with low water consumption.EASY MAINTENANCE with multiple devices for
easy inspection and maintenance.PLUG&PLAY AND MODULAR SOLUTION, easy
installation and high filtration capacity with
minimum footprint.
FILTRATION PHASE
Raw water enters from the inlet manifold to the coarse screen,trapping larger particles that could interfere with the filtercleaning mechanism -in vertical models, large and heavyparticles 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 waterflows out through the outlet manifold . Particles build-up createsa filter cake that increases the pressure differential between inletand outlet, and this activates the cleaning cycle when the pre-setpoint is reached.
SELF-CLEANING PHASE
Clean water supply is not interrupted when the cleaning cycle isactivated. The cleaning phase starts with the opening of the drainvalve, that creates a pressure gradient between the pressurizedinner filter and the atmosphere. At the same time, the suctionnozzle scanner spirals along the complete inner surface of the screen.
