In a Local Exhaust Ventilation System, which component removes the contaminants from the air?

Explanation:
In a Local Exhaust Ventilation System, the part that actually removes contaminants from the air is the cleaner. The hood captures contaminants at the source and sends the contaminated air into the system, but it’s the cleaner—such as a filter, cartridge, baghouse, or scrubber—that physically removes the contaminants from the air stream. After cleaning, the air moves through the duct and is exhausted outside. Without the cleaner, contaminants would just be transported with the air; with the cleaner, they’re removed before the air is discharged.
