Filter element is a professional term for filtration and purification function, mainly used to purify raw fluid resources, achieve resource separation and simple device. It is widely used in filtration industries such as oil filtration, air filtration, and water filtration. The following is a detailed introduction to the filter element:

1、 Definition and Function

Definition: The filter element is the heart of a filter, used to remove small amounts of impurities from the filter medium, protect the normal operation of equipment, or maintain clean air.

Function: The filter element can separate solid particles in liquids or gases, or allow different substance components to fully contact and accelerate reaction time. By filtering through the filter element, contaminated fluids (including oil, water, air, etc.) can be cleaned to the required state for production and daily life, that is, to a certain degree of cleanliness.

2、 Common types

Filter cartridges can be classified into various types based on their materials and purposes, including but not limited to the following:

PP filter element: also known as PP melt blown filter element, made of polypropylene ultrafine fibers hot-melt entangled, with a three-dimensional microporous structure, capable of intercepting impurities of different particle sizes.

Activated carbon filter: divided into compression type activated carbon filter and bulk type activated carbon filter, used to adsorb different colors, odors, organic matter, residual chlorine, etc. in water.

Ceramic filter element: made of pure natural physical materials, it has the advantages of not producing secondary pollution, retaining beneficial minerals in water, effectively removing mud, sand, bacteria, rust, etc.

Resin filter cartridge: It contains fine plastic balls (beads) that soften water scale through ion exchange.

Titanium rod filter element: It has the advantages of corrosion resistance, high temperature resistance, high strength, and easy filtration accuracy, and is suitable for filtering various corrosive media.

Folding microporous filter: made of materials such as polypropylene thermal spray fiber membrane, it has the advantages of small volume, large filtration area, and high accuracy.

3、 Working principle

The working principle of the filter element is based on the principle of physical filtration, which filters out impurities and particles in the fluid through the pore size and structural shape of the filter material. Specifically, when the fluid enters the filter element with a certain specification filter, its impurities are blocked inside the filter element, while clean fluid flows out of the filter element.

4、 Application Fields

Filter cartridges are widely used in various occasions that require filtration and purification, such as oil filtration, water filtration, and air filtration in industrial production; Water purifiers, air purifiers, etc. in family life; And places that require high cleanliness environments such as medical facilities and laboratories.

5、 Maintenance and replacement

The filter element will gradually accumulate impurities and dirt during use, which will affect its filtering effect. Therefore, it is necessary to regularly maintain and replace the filter element to ensure its normal operation. The specific maintenance and replacement cycle should be determined based on factors such as the material of the filter element, the usage environment, and the filter medium.

In short, the filter element is an essential component in the filtration and purification function, with a wide range of types, functions, and a simple and effective working principle. In practical applications, it is necessary to select appropriate filter material and structural design according to specific needs to ensure its filtration effect and service life.
