Cleaning and filtration The cleaning discharging valve opened The clean disc keeps still in the initial position The coarse particles are easily washed out of the filter The lower 1/3 screen also takes part in the filtration Filtration and self-cleaning action triggered 2/3 upper screen gets almost clogged Filtration starts on the whole screen surface The self-cleaning action is triggered by differential pressure Reverse flow in the screen entrance area still takes place Filtration also begins in the 1/3 screen. Filtration in progress The screen starts to gradually get clogged from top to down. Stage 1.Filtration in the upper 2/3 screen In the lower 1/3 reverse flow takes place as a result of high flow velocities in the filter screen entrance.

The AF filter works in BERNOULLI principle, which leads to the simple and highly reliable filtering operation. AF Filter removes debris and particles from natural water sources such as sea water or river water.

No filtration interruption when self-cleaningĮasy installation in horizontal or vertical positionġ,Typical applications: water treatment, circulating cooling system, heat exchanger protection, spraying nozzle protection, ballast water treatment system.Ģ,Applicable liquids: underground water, sea water, lake water, river water, circulating cooling water,sewage water, process water, cleaning water The AF series Bernoulli self-cleaning Filter (AF Filter for short) is designed for continuous filtration of water in pressurized systems. Wide flow rate range from 30 to 7000 m3/ h in only one filter unit Very low working pressure requirement down to 0.03MPa Low and consistant pressure drop (even <0.011MPa) both when clean and dirty

Non-contact cleaning, no particle extrusion out of the filter element, efficient filtration Simple and reliable structure with only two moving parts (Clean disc and discharging valve) Around the disc edge, the vacuum effect of lower static pressure makes the filtered water back-flush the filter element surface Flow velocity increases around the disc and the static pressure around the disc decreases because of the Bernoulli principle. 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. The filter element of AF filter is cleaned by the cleaning disc mounted on the pneumatic cylinder rod. The AF series Bernoulli self-cleaning Filter (AF filter for short) is designed for continuous filtration of water in pressurized systems.
