There are some misunderstandings about metal engraving machinery

Although the metal polishing dust collector is used for high dust concentration applications, many filters are used in the extraction system: the average dust concentration in the extraction air is usually very low, well below the lower explosive limit

Where does this difference come from? The clue is that the filter is clean. When air (low dust load) enters the filter, most of the particles will settle because the air velocity in the filter housing is very low and there is almost no turbulence.

For some applications, even a dust room without any filter elements is used, which is actually just a large room with dusty air inlets and clean air outlets: due to the low speed of the room, dust will settle. Only very fine dust particles remain in the suspension. In such dust chambers, they leave the air together with the air, and in the filter, fine particles will be deposited on the filter element. middle east cnc laser machine use oil mist collector

In order to prevent the filter element from clogging, air pulses are generated on the filter element from time to time to release fine particles. Therefore, for each cleaning pulse, a dense, very fine dust cloud is usually generated around the cleaning filter element. Moreover, since such pulses are often generated in the filter, dust clouds are often generated, and explosive gas is expected to be generated, at least in a part of the filter housing.
