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.​
