With a two - layer filter element collaborative design, the dual - stage filter achieves large - flow, high - precision impurity interception, combining efficient purification with long - cycle operation. It is the ideal choice for industrial and civil fluid treatment.
Double filter is also called double switch filter. It is composed of two stainless steel filters in parallel. It has many advantages such as novel and reasonable structure, good sealing performance, strong flow capacity, and easy operation. It can accurately ensure the filtration accuracy, and can quickly replace the filter bag, and filter basically no material. consumption, which reduces operating costs.
Fluid Inlet: The fluid to be filtered enters the filter through the top inlet and first flows into the primary filtration chamber.
Primary Filtration: The fluid passes through the outer large - pore filter element, initially intercepting large - sized impurities such as sediment and rust, reducing fluid turbidity.
Secondary Precision Filtration: The fluid after primary filtration enters the secondary filtration chamber and passes through the inner high - precision filter element, further trapping colloids, microorganisms, fine suspended solids, etc., achieving deep purification.
Clean Output: The fluid after dual - stage filtration meets the target cleanliness and flows out from the bottom outlet of the filter.

What is the replacement cycle of the filter elements in the dual - stage filter?
The replacement cycle of filter elements is affected by fluid impurity content and flow rate, generally 6 - 12 months. Replacement is recommended when the pressure difference between the inlet and outlet exceeds 0.15MPa.
Can the filter element combination be adjusted according to water quality?
Yes. According to actual needs, filter elements of different materials and accuracies can be flexibly combined. For example, activated carbon filter elements can be selected to remove organic matter, and 0.22μm pleated filter elements for bacteria removal.
What precautions should be taken during equipment installation?
During installation, ensure the correct inlet and outlet directions, and leave enough space before and after the equipment for easy filter element replacement. Regularly check the condition of the sealing ring to prevent fluid leakage.
The dual - stage filter serves as a key device for fluid purification in multiple industries, thanks to its dual - stage precision filtration technology, efficient and stable performance, and wide applicability.
