When it comes to ventilation, most people think of Air Condition or cooling-heating industrial vrf systems. However, there is also a situation where there is no need to interfere with the nature of air in the environment and only the circulation of ambient air is needed. This need is the most common in the hotel and hospital laundries, hot water vapor, heavy industrial production of the source steam, paint odor or chemical vapors, such as coal from the underground mining, paper, wood during the production of dust dispersed in the environment to be removed from the environment by removing or the air is ejected, and fresh air should be introduced.
There is a need to bring the ambient air to a point that does not threaten human health, as well as to increase efficiency in production. In this respect, the quality of ventilation systems and devices should not be compromised.
