Good air tightness can also reduce the accumulation of dust inside the filter cartridge, reduce the difficulty and frequency of dust cleaning, and improve the efficiency of the filter cartridge.

Filtration technology:

Advanced folding process: Lefilter dust filter cartridge adopts advanced folding process, folding the filter material into pleats and bonding them end to end to form a star-shaped filter cartridge. This structural design increases the surface area of the filter material and improves the filtration efficiency. At the same time, the gaps and angles between the pleats have been carefully designed to ensure even distribution of gas within the filter cartridge and prevent local airflow from being too fast or too slow, which affects the filtration effect.

Surface coating technology: Some Lefilter dust removal filter cartridges adopt surface coating technology, covering the surface of the filter material with a special film, such as polytetrafluoroethylene (PTFE) membrane. This film has excellent waterproof, oil-proof, and anti-corrosion properties, which can effectively prevent dust from adhering to the surface of the filter material, improve the dust cleaning effect of the filter cartridge, and extend the service life of the filter cartridge. For some dust-containing gases containing oil mist, water vapor or corrosive substances, surface coating technology can greatly improve the adaptability and filtration effect of the dust filter cartridge.

Intelligent dust cleaning technology: Lefilter dust filter cartridges may be equipped with an intelligent dust cleaning system that monitors the pressure difference inside and outside the filter cartridge in real time through sensors. When the pressure difference reaches a set threshold, the dust cleaning process is automatically started. This intelligent cleaning technology can clean the filter cartridge according to the actual usage, avoiding the problem of excessive cleaning or untimely cleaning, improving the dust cleaning efficiency, reducing energy consumption, and also reducing the impact on the filter cartridge. wear and tear, extending the service life of the filter cartridge.

Choosing a dust filter cartridge that suits your needs can be considered from the following aspects:

1. Understand the working environment

Dust type

Different industries and production processes will produce different types of dust, such as metal dust, mineral dust, fiber dust, chemical dust, etc. Understanding the properties of dust, including particle size, shape, hardness, viscosity, conductivity, etc., is essential for choosing a suitable dust filter cartridge. For example, for dust with high viscosity, it is necessary to choose a filter cartridge with an anti-stick coating or a special structure to prevent dust from accumulating on the surface of the filter cartridge and affecting the filtering effect.

Some dust may be corrosive, such as dust containing chemical components such as acid, alkali, and salt. In this case, corrosion-resistant filter materials should be selected, such as dust filter cartridges made of glass fiber, PTFE, etc., to ensure the service life of the filter cartridge in harsh environments.

Temperature and humidity

The temperature and humidity of the working environment will affect the performance and life of the dust filter cartridge. High temperature environment may cause deformation, aging, and even combustion of the filter material, so it is necessary to choose a high-temperature resistant filter cartridge. Common high-temperature resistant filter materials include Nomex, P84, etc. At the same time, high humidity environment may cause the filter material to be damp, reduce the filtration efficiency, and even cause damage to the filter cartridge. For high humidity environment, you can choose a filter cartridge with waterproof and moisture-proof properties, or add dehumidification equipment to improve the working environment.

If the working environment temperature and humidity change greatly, you also need to consider the thermal expansion and contraction properties of the filter cartridge and choose a product with good adaptability.

Gas composition

Understand the gas composition in the working environment, whether it contains flammable and explosive gases, corrosive gases, oily substances, etc. For environments containing flammable and explosive gases, dust removal filter cartridges with explosion-proof properties must be selected to ensure safe production. If the gas contains oily substances, it is necessary to select filter materials with oil-proof properties, such as polyester coated filter cartridges, to prevent oil mist from clogging the filter material and affecting the filtration effect.

2. Determine the filtration requirements

Filter accuracy

Determine the required filtration accuracy according to actual needs. The higher the filtration accuracy, the smaller the dust particles that can be intercepted, but it will also increase the resistance of the filter cartridge and reduce the ventilation volume. Therefore, it is necessary to balance the filtration effect and ventilation volume. Generally speaking, for industries with high requirements for clean environments, such as electronic manufacturing and pharmaceutical production, it is necessary to choose filter cartridges with higher filtration accuracy; while for some industries with relatively low requirements for air quality, such as construction and mining, filter cartridges with slightly lower filtration accuracy can be selected.

You can refer to relevant national standards and industry specifications to determine the filtration accuracy requirements suitable for your working environment.

Ventilation volume

Choose a suitable dust filter cartridge according to the ventilation volume required in the actual production process. Too little ventilation volume will lead to poor air quality in the working environment, affecting the health of workers and production efficiency; too much ventilation volume may increase equipment investment and operating costs. When selecting a filter cartridge, it is necessary to consider factors such as the filter area and resistance of the filter cartridge to ensure that the filtration effect is guaranteed while meeting the ventilation volume requirements.

The required ventilation volume can be determined by calculating factors such as the volume of the workplace, the number of people, and the operation of the equipment, and the dust filter cartridge of the corresponding specifications can be selected.

3. Consider equipment compatibility

Dust collector type

Different types of dust collectors have different requirements for dust filter cartridges. For example, bag dust collectors usually need to choose round filter cartridges, while filter cartridge dust collectors need to choose specially designed filter cartridges. When choosing a dust filter cartridge, you need to consider the type of dust collector you are using and ensure that the filter cartridge matches the interface size, installation method, etc. of the dust collector.

You also need to understand the working principle and performance characteristics of the dust collector in order to select a suitable filter cartridge and improve the overall efficiency of the dust collector.
