2022-01-04 Page view : 148 views


1.) Large flow rate of single filter element

2.) Low installation cost and low operating cost

3.) Small number of filter elements to be replaced

4.) 1 Micron absolute filtration accuracy

5.) High-quality special FDA filter material

6.) In-and-out filtering mode, all impurities are intercepted inside the filter element

7.) No metal frame, minimize the loss caused by discarding

8.) U-shaped sealing groove ensures high filtration efficiency


Replacement Method

 How to replace the front three-stage filter element:

Water will usually overflow during this process. Please prepare cleaning utensils such as a basin or towel.

a) Turn off the electroplating ball valve and pressure tank ball valve;

b) Open the gooseneck faucet to drain the residual water in the pipeline;

c) After the water no longer flows out, use the filter housing wrench to open the filter housing with the filter element;

d) Take out the old high-flow filter element and install the new filter element of the same specification;

e) Apply lubricant to the black “O” ring above the filter housing, and then put the “O” ring into the groove in the filter housing.

f) Tighten the filter housing in a vertical manner to avoid displacement of the “O” ring as much as possible.

g) Open the electroplating ball valve and the pressure barrel ball valve.



1.) Allow high-flow media to pass through the filter material, which has the advantages of high efficiency, low pressure loss and long life.

2.) The outer inlet and inner outlet structure of the high-flow filter element makes it easy to replace the filter element while keeping pollutants blocked on the outside of the filter element.

3.) There is a pp support frame inside the filter element, which can withstand a pressure difference of 0.245MPa at most.

4.) The β value of the filter element is above 1000.

5.) Multiple filter elements can be installed in the filter housing, which can use a wide range of flow, regardless of starting or continuous operation.

6.) The filter element is durable, and the filter can be configured in the least and most economical way.

The high-flow folding filter element meets the production requirements of the food, beverage, beer, chemical, pharmaceutical and other industries. It has high rejection rate, high throughput, low pressure drops and wide chemical compatibility. The production process adopts unique hot-melt welding processing technology, without any adhesive, and no foreign matter is released. The high-flow folding filter element with membrane as the core. After determining the material of the filter membrane, it is made of polypropylene non-woven fabric (net), divided into diversion layer and support. After folding, it is inserted into the center tube and installed in the shell. The hot-melt welding technology of the adhesive, the fusion seal constitutes a complete integrated filter element, does not contain chemical contaminants, and the product is 100% integrity tested.


The Structure of the Large-Flow Folded Filter Element:

 The 3M high-flow folding filter element is a double-layer polypropylene material discount structure, the inner layer is the final filter layer, and the outer layer uses a non-woven fabric with a pore size as the coarse filter layer, which plays a pre-filtering role. The inner and outer brackets are made of polypropylene or stainless steel. It is made of rigid material, so the filter element is a combination of pre-filtration and final filtration.

Large flow pleated filter element with filtration accuracy of 0.10, 0.22, 0.45, 0.65, 0.8, 1, 3, 5 with eight pore sizes, which can be selected according to different requirements of users.


Advantages of Large Flow Folded Filter Element:

Structural filtration area is large, the initial pressure difference is low, the flow rate is fast, the filter volume is small, and the cost is low. Due to the combination of pre-filtration and final filtration, the filter element has a large dirt holding capacity. The service life is longer than that of a single pore size filter element. A single pure polypropylene material is easy to judge its chemical compatibility.


Large Flow Folding Filter Element Disadvantages:

Because of the paper folding of the filter layer, the working pressure generally cannot exceed 0.3Mpa. If the pressure exceeds the pressure, the micropores will expand, and the solids are easy to filter. Especially the working temperature is greater than 60℃, and the recoil effect is not ideal.
