The AF series Bernoulli Filter is designed for continuous filtration of water in pressurized systems. AF Bernoulli Filter removes debris and particles from natural water sources such as sea water or river water. The AF filter works in BERNOULLI principle, which leads to the simple and highly reliable filtering operation.



BERNOULLI CLEANING PRINCIPLE

The filter element of AF Bernoulli filter is cleaned by the cleaning disc mounted on the pneumatic cylinder rod. When the cleaning action triggered, the disc moves into the filter element and water passes through the gap between the disc and the filter element. Flow velocity increases around the disc and the static pressure around the disc decreases because of the Bernoulli principle. Around the disc edge, the vacuum effect of lower static pressure makes the filtered water back-flush the filter element surface.
