Bernoulli Automatic Self Cleaning Filter AF Seires for Pond Water Treatment

Description

The AF Series Bernoulli Self-cleaning Filter ( AF Filter for short ) is designed for automatic continuous filtration of water in the pressurized systems. AF Filter removes debris and particles from natural water sources such as sea water or river water. It is the ideal solution for the coarse water filtration ranging from 200μm to 2000μm. The AF filter works in Bernoulli Effect Principle, which leads to the simple and reliable filtering operation. It cleans the filter screen with surface cross flow and the back-flushing flow, which brings higher particle removal efficiency than the conventional brush filter. Many particles larger than the screen aperture are extruded through the screen when a brush filter is brushing and cleaning.

The filter screen of AF Bernoulli Filter is back-flushed d by the cleaning disc inside, which is mounted on the piston rod driven by the pneumatic cylinder. When the cleaning action triggered, the disc moves into the filter screen and the water passes through the gap between the disc and the filter screen inner surface. Flow velocity is accelerated when the water passses the gap, while the static pressure around the gap is reduced because of the Bernoulli Effect Principle. Around the disc edge, the vacuum effect of lower static pressure back-flushes the filter screen inside surface with the filtered water.
