Product Description

Bernoulli Self Cleaning Filter AF Seires for Spray Nozzle Protection

 

 

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.

 

Bernoulli System pioneered the application of the Bernoulli Principle, named after the Swiss scientist Daniel Bernoulli, to water filtration. The distinguishing feature of a Bernoulli Filter is a disc mounted on a pneumatic cylinder, which enables contactless cleaning of the filter. The cleaning sequence itself is automatic and continuous, requiring no manual intervention.

 

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.

 

Filter Screen

 

AF Bernoulli Filter mainly uses the slotted screen, which can be easily back-flushed clean and rarely get clogged. the slotted screen has the uniform and precise slots and very long service life. The filtration degree ranges 200μm to 2000 μm. 304, 316L, duplex 2205 are available for screen material. The 304 is ecomonic and suitable for the normal fresh water. the 316L is for the normal anti-corrosion request against the sea water. The duplex 2205 is the most ideal screen material for the long service life in the sea water.


The perforated screen is also vailable for the coarse filtration larger than 1000 μm if specially requested.
