Product Introduction

AR Series Salt Water Auto Backflush Multi-cartridge Self Cleaning Filter


Brief introduction

AR Series is a new generation self-cleaning filter independently designed by Shanghai JCI with our own intellectual property. It is designed with integrated multiple aperture-type filter screens in the inner part. When the filter screens are blocked, the unique back-flushing turning arm will clean the filter screens one by one. As a high-end self-cleaning filter, AR Filter is designed for the customers mainly concerning product quality and high reliability, using the world's top quality key components (such as filter screens motor, self-cleaning control system, etc.) .


The AR filter has the outstanding advantages of distinguishing common screens type self-cleaning filter. AR filter has the precision range being 30-2000 microns. It utilizes extremely rugged V-shaped wadge net filter screen with high surface gap accuracy. Stand- alone machine has very large filter area, fine filtration on low surface flow rate. Single filter super large flow rate is 8000m3/h. Owning very high reliability, it can be competent for the worse water quality, such as oily sludge-like impurities, soft viscous impurities, high impurity content, a small amount of hair and fibrous impurities.


AR filters can remove all kinds of solid particles of impurities from water and low viscosity liquids (such as seawater, machined cooling water) to meet liquid cleanliness requirements of the system operation and the next process. It can also be used to protect the downstream key equipment from particle clogging, wear or scaling to improve its operation efficiency and life. AR filters can be fully automated online continuous filtration, reducing shutdown cost maintenance cost and human cost. It is an advanced solution for the water and water-based liquid filtration.

How Does It Work?

Filtering process

Liquid flows into the filter via the inlet, and then flows through the internal surface of filter screen and goes out from the outlet. Impurities are intercepted on the inner surface of the filter screen and the filter cake slowly accumulates, which leads to gradually pressure drop increasing between the inlet and outlet. The flux of the filter screen becomes lower.

Back-flushing process

When it reaches the preset pressure drop or time, the self-cleaning program is triggered. The gear motor drives the back-flushing turning arm aiming at one filter screen. The upper end of the screen is sealed, and the lower end is connected to the cleaning nozzle. And then the cleaning valve opens and connect the screen and discharging pipe. The differential pressure between the filter

element' s outside and discharging nozzle will make the filtrate back-flush the filter screen, filter cake dislodged and be purged downward into the sewage pipe.

Positioning device

Positioning disc and cleaning turning arm are installed on the shaft driven by the gear motor. Each positioning hole on the disc matches each screen and cleaning arm is corresponding to one hole. When one hole reaches the channel of positioning sensor, the sensor output the signal to stop the gear motor. The cleaning arm has aimed at one element at the same time. The cleaning 

valve opens for several seconds till the element is cleaned. Then the gear motor continues rotating. When the next hole on disc reaches the sensor channel, the gear motor will stop and the next screen is cleaned.

Automatic Cleaning Control System

AR filter is equipped with automated cleaning 
control system, integrated differential pressure
cleaning and timing cleaning parallel control
 function, which controls its efficient working, 
according to the operating conditions. If 
necessary, the system is able to realize real-
time and remote monitoring of DCS by custom.
Differential pressure cleaning is the most 
efficient cleaning mode, which reflects the  
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.

The automated differential pressure controller has two kinds of forms, differential pressure switch and differential pressure transmitter. The transmitter can output the real time pressure differential value with higher sensitivity and reliability, to facilitate long-distance and real-time monitoring of the DCS.
