The Difference Between Straight-Through Filter And Angle Filter

Filters are common equipment in industrial and engineering fields and are used to separate solid particles or other impurities to protect the normal operation of equipment and systems. In the classification of filters, straight-through filters and angle filters are two common types. This article will analyze the differences between these two filters from the perspectives of working principles, application fields, advantages and disadvantages, etc.

Working Principle

Pass-through filter:

A straight-through filter, also known as a pipeline filter, is a device that achieves filtration by installing a filter screen or filter medium in a fluid pipeline. The fluid flows in from the inlet of the filter. Under the action of the filter screen or filter media, the solid particles are blocked, and the clean fluid flows out from the outlet.

Angle filter:

The angle filter is a cylindrical structure that guides fluid into a cylindrical structure with a filter element installed inside. Through the rotational motion of the fluid, solid particles are separated and gathered on the surface of the filter element. Clean fluid passes in and out of the center of the filter element, thereby achieving filtration.

Application Field

Direct pass filter: Direct pass filter is widely used in fields that need to handle large amounts of fluids, such as water treatment in industrial production, chemical industry, oil and gas, etc. Its simple structure and high flow processing capabilities make it widely used in scenarios that require efficient filtration.

Angle Filters: Angle filters perform well when handling highly viscous liquids, thick liquids, or media with large particulate matter. Commonly used in food processing, pharmaceuticals, coatings and other fields, these fields require finer filtration of fluids to ensure product quality.

Advantages and Disadvantages

Advantages and Disadvantages of Direct Pass Filters:

Advantages: high flow processing capacity, suitable for large-scale production; relatively simple structure, easy maintenance; suitable for some general particulate matter filtration.

Disadvantages: For some small particles or high-viscosity fluids, the filtration effect may be poor; it is not suitable for situations where the particles in the liquid are unevenly distributed.

Advantages and disadvantages of angle filters:

Advantages: It can handle high-viscosity liquids, large particles, etc.; the filtration effect is relatively good and can capture smaller particles; it is suitable for fine filtration requirements in specific fields.

Disadvantages: The structure is relatively complex, and installation and maintenance are cumbersome; the flow processing capacity is relatively low, and it is suitable for small-scale production.

Both straight-pass filters and angle filters are devices used to achieve filtration purposes in different application scenarios, and each has some advantages and disadvantages. Selecting the appropriate filter type depends on specific needs, such as the nature of the fluid, particle size, processing scale, etc. In engineering and production, understanding the differences and applicable scope of these two types of filters can better select the appropriate filtration solution to ensure high efficiency and quality of fluid treatment.
