1、 Working principle of dual filter

The dual filter cartridge is equipped with a stainless steel filter screen and a filter support basket, and a vent valve is installed at the top to discharge the air inside the filter; The connection between the upper cover and the filter cartridge adopts a quick opening structure, which is more convenient for cleaning and replacing the filter screen. The inlet and outlet valves are opened and closed by three-way ball valves, which are pressure and temperature resistant, and operate flexibly and conveniently.

3、 Characteristics of dual filter

1、 Continuous work without stopping the machine

When the filter element of a traditional single cylinder filter becomes clogged to a certain extent during operation, the main engine should be stopped before cleaning or inspection. The dual filter solves this problem by using two three-way ball valves to assemble two single cylinder filters on one machine base. When cleaning the filters, there is no need to stop the machine to ensure continuous operation.

2、 Quick opening structure, easy to replace and clean

The upper cover of the dual filter is connected to the filter cartridge using a quick opening structure, which is more convenient for cleaning (replacing) the filter screen. The three adjustable feet allow the filter to be placed smoothly on the ground. The connecting pipelines are connected by flexible joints or clamps, and the inlet and outlet valves are opened and closed by three-way ball valves, which are pressure and temperature resistant, flexible and convenient to operate, and have no material or liquid leakage, making them more hygienic.

3、 Stainless steel material, corrosion-resistant

The dual filter can be made of 304 stainless steel and 316 stainless steel materials, suitable for handling various acidic and alkaline liquids, solvents, and neutral liquids.

4、 Novel and reasonable structure, good sealing performance

The dual filter has many advantages such as novel and reasonable structure, good sealing, strong flow, and easy operation, making it a widely used equipment.

5、 Low chance of side leakage

The probability of side leakage of the dual filter bag is small, which can accurately ensure the filtration accuracy and quickly replace the filter bag. The filtration has basically no material consumption, greatly reducing the operating cost.
