Automatic VDF filters
The water arrives through the inlet manifold, undergoes a pre-filtering and from there passes internally to the main cartridge that
filters from the inside out, this sieve retains the dirt
inside and the already clean water passes to the outlet collector.
The retained dirt creates a pressure difference and causes the valve to open dedes load producing a reverse motion that causes the filter to be cleaned.
This causes a rotary axial movement that creates a depression in the nozzles that by vacuum absorb the dirt and eliminate it by the drainage collector.
When this process is finished, it returns to its initial position and the process is finished.
