Question

The fan which removes air or gases from a space by suction is:

• A. Exhauster
• B. Blower
• C. Washer
• D. Drier

Hint:

Exhauster = sucks out air — blower = pushes in air!

Answer 1

The Correct Option is A

An exhauster is a type of fan or device used to remove air, fumes, or gases from an enclosed space by creating suction.
It draws out stale or contaminated air and helps maintain good ventilation.
Exhausters are commonly used in factories, kitchens, and ventilation systems.
A blower pushes air into spaces under pressure rather than removing it by suction.
A washer cleans air by spraying water or chemicals but does not remove it by suction.
A drier removes moisture from air or substances but is not a fan for air removal.
So, the fan that works by suction is called an exhauster.
