Product Description

Bernoulli Automatic Self Cleaning Filter AF Seires for Cooling Circulating Water Filtration

 

 

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.

 
 

 

Bernoulli Self-cleaning Working Principle

 

A.The flushing sequence is initiated by a timer setting or triggered by a differential pressure sensor before any blockage of the filter basket causes flow reduction.

B.In the pre-flushing stage, the flushing valve opens and larger particles are flushed out.

C.During the flushing sequence, a specially shaped flushing disc mounted on a pneumatic cylinder enters the filter basket and creates a gap between the disc and the filter basket.

D.As the flow velocity increases locally around the disc, the static pressure is reduced in accordance with the Bernoulli Principle and the direction of the flow is reversed, thus releasing particles which are stuck to the surface of the filter basket.

E.The released particles are led out from the filter through the flushing outlet.
