1. AFB series is a new type of self-cleaning strainer independently developed by Shanghai JCI with our own intellectual property. It is designed for continuous online filtration to remove impurities on the inner surface of filter screen via highly-efficient mechanical scrapping.

2. AFB Filter can quickly remove impurities from the surface of filtering screens, thus removing more impurities with high efficiency. It applies to the filtration of water and various low viscous liquids. AFB Filter designed and manufactured as per Shanghai JCI's standards for high performance, high quality and high reliability, it features internationally first-class quality.

3. AFB filter always keeps the filter element clean by its advanced self-cleaning mode, and discharge the waste liquid containing high concentration impurities to reduce material waste. It is more obvious efficient to filter water with poor quality and low viscosity liquid . AFB Filter with notable technical advantages and low operation costs, it has gradually displaced the traditional manual filters in various fields, such as vibrating-screen filters, bag filters, basket filters, etc.

Filtering status(see figure 1)
Liquid flows inside from the inlet.The liquid flows outwards from the inner surface of the filter screen, and the impurities are intercepted on the inner surface. Then, the liquid flows out from the outlet; with the passage of time, the impurities gradually increase, and differential pressure rises. We can begin to clean the filter screen according to the preset differential pressure or the timing.

Cleaning status(see figure 2)
The motor drives the scraping brushes to rotate horizontally to clean the filter screen. When the brushes rotates, impurities are scraped off and filtered along the filter net to the bottom of the filter, and the impurities with large specific gravity are deposited into the dirty collector. Each cleaning is made up of a number of strokes. After the filter screen is cleaned, the filtering ability is restored. No filtration interruption while self-cleaning.

Discharging status(see figure 3)
After a number of cleaning cycles, impurities accumulate to a certain amount. Regular opening of drain valve, and the waste liquid containing high concentration of impurities is discharged. which can also be recycled, if necessary.

■ Horizontal rotary scraping, scraping off the impurities directly, is good at filtering viscous liquids and removal of viscous, soft and suspended impurities;
■ Simple structure, easy dismounting; after removing the scraper, easy to take out the filter screen, and easy to clean the inside;
■ Automatic operation, continuous online filtration, to end up the heavy filter screen replacement and cleaning work;
■ Do not produce disposable filter material, saving consumables costs and environmental costs;
■ Small filtration pressure loss, stable flow rate, energy saving is beneficial to the continuous stability of the whole process;
■ Sealed filtration, preventing dangerous material leakage, is advantageous to the safe production and the staff health;
■ Discharge waste liquid with high impurities concentration can be recycled, to reduce the loss of high-value materials;
■ A variety of advanced control systems are optional, powerful, efficient and reliable;
■ Selection of world-renowned brands of components, high reliability, low costs.

Automatic Cleaning Control System
Accumulation of of filter cakes and the blocking of the filter element. When the preset pressure differential is reached, it starts the self-cleaning action. It is suggested that the cleaning pressure differential is 0.1MPa, which can be adjusted within the scope of 0.01-0.1MPa, by the working conditions. Periodically cleaning can be set 0-24 hours, and if the differential mode is inefficient, time pattern still works. It can be considered as the ultimate protection. The cleaning period setting should be close to the average period of the filter pressure differential cleaning mode.
