ATZQ-120-200 auto backwash filter – PLC control, no interruption.

1. Product Introduction

Aite ATZQ-120-200 Automatic Backwash Filter is composed of a cylinder, stainless steel filter, blowdown part, transmission 

device, and electrical control part. Aite ATZQ-120-200 Automatic Backwash Filter can filter industrial wastewater, circulating 

water filtration, metallurgy industry continuous casting water, blast furnace water, and more. It is widely used in metallurgy,

 chemical industry, petroleum, paper, medicine, food, mining, electric power, and urban water supply fields.

Aite ATZQ-120-200 Automatic Backwash Filter is engineered as a fully interchangeable substitute for original 

models – maintaining identical dimensional parameters, interface specifications, and filtration performance to enable

 direct drop-in installation without any housing modifications.

As a professional manufacturer specializing in industrial water filtration equipment, we deliver Aite ATZQ-120-200 Automatic 

Backwash Filter with stable performance, reliable construction, and competitive pricing for industrial facilities worldwide.

2. Working Principle

Aite ATZQ-120-200 Automatic Backwash Filter operates through a proven self-cleaning process:

Water enters through the inlet, passes through a coarse screen to filter out larger particles of impurities, and then reaches a 

fine screen. In the filtration process, the fine filter screen gradually accumulates dirt and impurities in the water, forming the

 filter impurity layer. Because the impurity layer is accumulated on the inside of the fine filter screen, a pressure difference is 

formed on both sides of the fine filter screen.

When the pressure difference of Aite ATZQ-120-200 Automatic Backwash Filter reaches the preset value, the automatic cleaning

 process begins. The water supply is not interrupted, the cleaning valve is opened, and the water pressure in the cleaning 

chamber and the suction device decreases significantly. Through the pressure difference between the filter cylinder and the 

suction pipe, the suction pipe and the cleaning chamber produce a suction, forming a suction process. At the same time,

 the electric motor drives the suction pipe to spiral along the axial direction. The combination of axial and rotating motion 

of the suction device cleans the inner surface of the entire screen. The flushing process takes only a few seconds. The

 blowdown valve closes at the end of cleaning. Aite ATZQ-120-200 Automatic Backwash Filter is ready for the next flush cycle.
