Repeated breathing in our daily lives is the process by which humans breathe through the mouth or nose and exhale, which is the greatest act of human life.

This respiration is the act of absorbing the oxygen contained in the air inside my body and releasing the carbon dioxide present in my body. The quality of the air will have a great influence on the respiratory system, and it will be the most closely related to human healthy life.

It is undeniable that human life has been enriched by the recent industrial development, but on the contrary, harmful substances such as various kinds of soot emitted from factories and vehicles are exposed more in the air, and the quality of the air is getting worse As a trend, it threatens human breathing and healthy life through it.

In addition, there are particles in the air that contain many particles that are not visible to the naked eye. These particles flow into the respiratory system of the human body every time we breathe. Therefore, depending on the quality of the air, Lt; / RTI >

On the other hand, in recent years, there are many harmful particles in the air, and they are reported to be adversely affecting the respiratory system of the human body by these harmful particles, and they are recognized as a very dangerous factor in health.

As a result, many efforts have been made to use air purifiers or to introduce air purification systems to purify air at homes, hospitals, large buildings, factories, and the like.

Particularly, there is a dust collector for collecting fine particles by sucking air containing a large amount of fine particles and passing them through a filter, and then discharging clean air with fine particles removed to the atmosphere, and a dust collector for collecting fine particles contained in the air Depending on the operating principle, it is classified into various types such as mechanical, electric, dry, and wet.

Generally, a dust collector sucks air into an air inlet, filters the air through a filter, and discharges the air.

However, in many cases, a large amount of moisture is contained in the air filtered by the filter, which is sucked into the suction port of the dust collector. In particular, when cutting or polishing using a machine tool, cutting oil supplied in the form of mist And a large amount of water is contained in the air.

When the air containing moisture is filtered by the dust collector, moisture contained in the air is absorbed by the filter, thereby deteriorating the filtering function of the filter. That is, if the moisture is too much, the dust collector is not operated.
