3A-AC ™ G Series Fully Automatic Scraper Filter

Scraper self-cleaning filters can be equipped with 25 micron to 3500 micron filter elements, DN25-DN200 caliber for different requirements. Widely used in industrial circulating water

Filtration, paint production preparation purification filtration, resin pre-canning filtration, landfill leachate pretreatment and other fields.

The 3A-AC ™ G series internal scraper self-cleaning filter is mainly suitable for fluids with high gravity particles and viscosity in the filter medium.

working principle

When the pressure difference between the inlet and outlet of the brush self-cleaning filter and the inner scraper self-cleaning filter reaches a preset value, the filter will start the self-cleaning process. The entire self-cleaning process includes two

Steps: open the drain valve located on the upper end cover of the filter; the motor drives the two stainless scrapers in the body filter to rotate, so the impurities captured by the filter are brushed by the scraper and removed

Drain valve. The entire cleaning process takes about 15-60 seconds. The system continuously flows during cleaning. The entire running process of the filter is controlled by a control box provided with the filter.

Performance characteristics

Uninterrupted water supply: There is very little water during cleaning, which is 1% of the water output of the filter, and the flushing time is 15-60 seconds. The entire system is uninterrupted water supply.

High filtering accuracy: Ultra-high filtering accuracy can reach 25 microns, and there are various filtering screens for you to choose from.

Large filtering area: The effective filtering area of ​​the standard filter is 7 to 40 times the inlet area.

Reliable cleaning: there are multiple control methods, such as manual, differential pressure, time, PLC program logic control, etc.

Economical and simple installation: The structure is diverse and suitable for installation in various situations on the site without affecting the operation effect.

The cleaning components are interchangeable: the scraper material is PTFE, stainless steel, and can be selected according to different working conditions.

Long service life: the service life is more than 10 years under normal conditions, and the filter is stainless steel, which can be easily replaced as needed

Filters of different specifications.
