The industrial ventilation system is an essential part of any production plant, manufacturing facility, or commercial building where a large number of people are frequently gathered. An industrial ventilation system eliminates contaminated air and replaces it with fresh, clean air, thereby reducing the chance of employees falling ill due to exposure to hazardous contaminants. There are two main types of industrial ventilation system; each one is best suited to a specific range of applications.
The first common type of industrial ventilation system uses dilution ventilation. Systems that use dilution ventilation reduce the amount of air contaminants by simply introducing clean air into the environment and allowing the two to mix together. Industrial ventilation systems that use dilution ventilation often involve large exhaust fans on walls or roofs.
Dilution ventilation is most useful in facilities where air pollution and toxicity levels are relatively low. If you are looking for an industrial ventilation system to deal with low grade contaminants like the basic airborne microbes that are present in every office building and communal workspace, dilution ventilation is probably a good choice for you.
The other most common type of industrial ventilation system uses local exhaust ventilation. Local exhaust ventilation is more complicated than dilution ventilation. It involves actually capturing and expelling air contaminants instead of just diluting them with fresh air.
A local exhaust ventilation system requires a hood or comparable opening for capturing contaminants and a series of ductwork for moving the polluted air out of the area. It also includes an air filtration system that cleans the contaminated air as it moves.
Industrial ventilation systems that use local exhaust ventilation are useful in facilities that have more contaminants and higher levels of toxicity in the air, as they can efficiently remove pollutants that could cause serious harm to employees working in said facilities.
All commercial buildings could benefit from installing an industrial ventilation system, but which type should be installed depends on the specific application.
