9 Types of Common Industrial Filters

Mengfei Filtration is dedicated to making high-quality industrial filters. Please contact us for your filtration solutions.

Industrial filtration is a technology used in industries.  It helps remove impurities, particles, and pollutants from liquids, gases, and solids.This process guarantees smooth production runs and maintains product quality. It has many types and uses. These include gas power plants, natural gas plants, pipeline transport, the medical industry, and the food industry.

Common industrial filtration includes: air filtration, liquid filtration, gas filtration, membrane filtration, etc. They have their own advantages, uses and operating conditions. The following are some of the main types of industrial filters:

1. Mechanical filter:

There are two types of mechanical filters:

Bag filter: A bag filter is a versatile filtering device.It has novel design, small size and easy to use. It saves energy and works efficiently. People mainly use it for liquid separation, and it works through pressurized filtration.

Mesh filter: Mesh filter is a device used to remove impurities in the medium. It is often installed at the inlet end of the pipeline system to protect the normal use of valves and equipment. ‌

2. Depth filter:

The depth filter is a common industrial water treatment filter. It uses multiple layers of filter media, usually including quartz sand, activated carbon and ceramic particles. Through filtration systems, it can effectively remove harmful solid suspended matter, particles and organic matter in the water.

Depth filters are widely used in industrial filtration.It plays a vital role.

The industries including water, medicine, food and so on , with good filtration performance and long life.

3. Activated carbon filter:

Activated carbon filter is a water treatment equipment.The adsorption effect of activated carbon plays a vital role.

Activated carbon filter has a rich micro-porous structure, which helps remove harmful impurities away.

The suspended particles, organic matter, residual chlorine in the water are harmful. We should clean them up ,to improve water quality and extend the service life of subsequent treatment equipment.

4. Membrane filter:

Membrane filter is a high-efficiency filtration product.It uses special membrane materials to separate and clarify different components in liquids. Its main functions include removing suspended particles, bacteria, viruses and other impurities in liquids to achieve the purpose of purifying liquids.

The types of membranes include reverse osmosis, nanofiltration, ultra-filtration and micro-filtration (depending on the size of the pores). Membrane filters have the advantages of easy operation, high filtration efficiency, low energy consumption. They are widely used in water treatment, food and medical industries.Membrane filters are extremely important in modern industrial production.

5. Electrostatic filter:

Electrostatic filter is a technology that can remove static charge and particles from the air. It can attach or intercept particulate matter in the air, thereby improving air quality. It can remove harmful particles away from the air,as small as 0.01 microns.

It works stably without noise, and has a long service life. People use Electrostatic filters in various scenarios, such as aviation, hospitals, production workshops, laboratories, etc.

6. Oil-water separator:

Oil-water separator is widely used in industrial production, environmental protection treatment and other fields.The working principle is mainly based on the difference in physical properties between oil and water, especially the difference in density.

It can separate the oil and water in oil-wastewater to achieve the purpose of purification and recycling. People use oil-water separators in many fields: such as petrochemical, metallurgy, mechanical processing, food processing, etc.

7. Cyclone filter:

Cyclone filter, also known as cyclone separator, is a solid-liquid separation equipment .It is based on the principle of rotating airflow, commonly used in industrial dust purification and environmental protection fields. Its working principle is to separate and collect dust by relying on the rotation of gas and the action of centrifugal force.

It is widely used in industrial fields, such as cement industry, coal industry, tobacco industry, medical industry, etc..It is used to clean industrial air . In addition, it can also be used in fields such as air conditioning and drying.

8. Magnetic filter:

Magnetic filter is a purification device that uses the principle of magnetic separation, also known as magnetic field filter. It usually contains strong magnetic materials and blocking filters.

When the fluid passes through, the ferromagnetic impurities will be adsorbed on the magnetic material.Thereby，people can achieve the purpose of separation and purification.

People use magnetic filters in many fields, including hydraulic systems, fuel systems, food industry, steel mills, etc.

9.Gas filter:

Gas filter is a device that filters and purifies harmful substances in gas.

Through different ways, impurities are firmly “locked” on the filter media ,such as physical barrier, electrostatic adsorption, chemical adsorption, etc.,while pure air can pass smoothly and continue its flow path.

People use it in industrial production, medical and health, environmental protection and other fields. Gas filters can be divided into different types, ,according to different filtering principles and application scenarios, ,such as activated carbon filters, HEPA filters, UV-C light disinfection filters, etc.

10. Condensate Filter:

A condensate filter is a device used to treat and purify condensate. Condensate generally refers to moisture formed by cooling gas in air conditioning, refrigeration equipment or other cooling systems. This moisture may contain impurities, dirt or chemicals, so we need to clean it to protect subsequent equipment and systems.

Condensate filters are important in many application scenarios, such as in commercial air conditioning systems, industrial cooling towers and refrigeration equipment.

Different types of filters differ in design and application. Choosing the right filters requires comprehensive consideration of factors ,such as specific process requirements, filter media, flow rate, and impurity properties.
