Brush type auto backwash filter – self-cleaning, no interruption.

1. Product Introduction

Aite Brush Type Pipeline Automatic Backwash Filter is a type of automatic self-cleaning filter suitable for harsh 

environments. For different use requirements, Aite Brush Type Pipeline Automatic Backwash Filter can be equipped 

with 3500–50 micron screen and 8"–36" caliber. The filter self-cleaning process is initiated by a differential pressure 

switch that monitors the differential pressure at the inlet and outlet of the filter at all times. The differential pressure 

switch is usually preset to 0.5 bar (7 psi).

Aite Brush Type Pipeline 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 Brush Type Pipeline

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

worldwide.

2. Working Principle

Aite Brush Type Pipeline Automatic Backwash Filter operates through a proven self-cleaning process:

When the pressure difference between the filter inlet and outlet reaches a preset value, the filter will start the

 self-cleaning process. The whole self-cleaning process consists of two steps: opening the blowdown valve on the

 upper cover of the filter; and the motor driving the two stainless steel brushes in the body filter screen to rotate – brushing

 down impurities caught by the filter screen and discharging them from the blowdown valve. The whole cleaning process

 takes about 15–60 seconds. The system does not interrupt the flow during cleaning. The whole operation process of Aite

 Brush Type Pipeline Automatic Backwash Filter is controlled by a control box.
