What is the general exhaust air volume of an exhaust fan?

[HeidiDella]

Generally speaking, the air volume of an exhaust fan with an opening of about 300mm is 200-400 cubic meters per hour. The commonly used product with an opening of 280mm*280mm has an exhaust air volume below 240 cubic meters per hour, which means the volume of air discharged per minute is below 40 cubic meters, generally 4-6 times the room's space volume. Below is a related introduction to the low air volume from car air conditioning vents: 1. Specific reasons: Incorrect air direction selection in car air conditioning, a faulty blower can lead to small air conditioning vents, and a dirty air filter can obstruct the airflow. 2. Solutions for low air volume from car air conditioning vents: Owners can regularly clean the air filter, using a vacuum cleaner to remove dust from the filter or an air compression gun. If the filter is too dirty, it is recommended to replace it. The price of an air filter is not expensive, and the replacement cycle is 10,000 kilometers or half a year.
