What defines the term "exhauster" in an exhaust ventilation system?

The term "exhauster" in an exhaust ventilation system is best defined as a component that helps remove contaminated air. This role is critical in maintaining air quality and ensuring a safe working environment, particularly in construction and other industrial settings where hazardous fumes, dust, or other pollutants may be present. The exhauster functions by creating a negative pressure that pulls contaminated air out of the workspace, thereby reducing the concentration of harmful substances and providing cleaner air for employees.

In contrast, while cooling the workspace and purifying the air are important functions within ventilation systems, these are typically performed by different types of equipment, such as air conditioning units or air purifiers, rather than an exhauster. Additionally, measuring air quality is carried out by specific tools designed for that purpose, but this does not relate directly to the fundamental function of an exhauster in handling contaminated air. Thus, the core definition accurately emphasizes the exhauster's primary role within exhaust ventilation systems.
