Directly extract dust from fully enclosed or semi-enclosed sources.

Most applications that draw directly from the source involve lighter and particularly lighter dust, sometimes mixtures, such as laser dust and smoke.
However, heavier dust is more common in the machining field.
If the dust cannot float in the air, you need to install the nozzle as close as possible to the dust source.
The diameter of the nozzle is generally between 25 mm and 100 mm.
The air volume at each suction point is generally between 60 cubic meters per hour and 1000 cubic meters per hour. The negative pressure required by the system is generally between 120 mbar and 280 mbar.

The dust removal system that directly extracts dust from the source often needs to use the control system to achieve linkage with the production equipment, and sometimes it may also need a monitoring system and a signal alarm function.
In many cases, if the supporting source dust extraction system does not work properly, its services and connected production equipment cannot be up and running.
The performance of the dust removal system that extracts dust from the source will directly affect the quality of the product and whether it can pass the quality inspection.
Therefore, it is very important to carefully design the source dust extraction system and select the matching high-efficiency filtering device and monitoring device.​

Surface cleaning refers to the use of accessories connected to the suction tube to suck the material and transport it to a collection container located in front of or below the filter device.
When choosing a vacuum cleaner for cleaning, you need to know the detailed specifications of the material to be sucked.

The choice of vacuum cleaner specifications and models depends on the properties of the suction material and the requirements of the application environment.
Lighter and finer dust require lower negative pressure value and general average air volume, but often require larger filter devices or even special filter devices.
The heavier suction material requires a higher negative pressure value.
The proportion of fine powder contained in each absorbed substance or even heavier substances (such as sandblasting) must be taken into account.

For dust removal applications that can float dust, we call it dust extraction. Floating dust is very light and can float up on its own.

For dust extraction tasks, we usually use a dust hood with a mobile arm or directly interface with the closed interface on the production equipment.

For dust removal applications with small air volume, such as the dust generated when a small amount of powder is manually added, a large air volume industrial vacuum cleaner can be used, which can also be used for post-cleaning.

However, most cases require higher air volume.

For air volume requirements of 1000 to 16000 cubic meters per hour, dust extraction equipment is suitable.

The air volume requirement is generally between 1500 and 16000 cubic meters per hour, and the corresponding negative pressure requirement is generally only 40 mbar. If the piping system is long, it may be necessary to increase the drive to increase the negative pressure in the system to a maximum of 120 mbar.

For high-volume dust removal applications, it is particularly important to choose the filter area and dust load of the filter device correctly. Compared with a large central dust removal system with many dust suction points, the use of a decentralized local dust extraction system and a filter device with automatic cleaning function and a shorter piping system helps to achieve better dust removal effect and better Use experience and lower operation and maintenance costs.
