An exhaust fan is a device that can exhaust indoor air, commonly found in kitchens, bathrooms, and other places that require exhaust. Below you will find the specifications of an exhaust fan, including size, speed, noise, and airflow.
Size
The size of an exhaust fan usually refers to the diameter of the fan blades, which generally come in different sizes such as 6 inches, 8 inches, and 10 inches. The larger the size, the greater the airflow, but it also comes with greater noise and higher power consumption.
Rotation speed
The rotation speed of an exhaust fan is usually expressed in revolutions per minute (rpm), and there are generally different speeds such as 1,000 rpm, 1,200 rpm, and 1,500 rpm. The higher the speed, the greater the airflow, but it also brings more noise and higher power consumption.
Noise
The noise of the exhaust fan is usually expressed in decibels (dB), and there are generally 30dB, 40dB, 50dB and other different noise. The lower the noise, the more comfortable it is to use, but it also brings the problem of insufficient airflow.
Air volume
The air volume of the exhaust fan is usually expressed in cubic meters per hour (m3/h), and there are generally 200m3/h, 300m3/h, 400m3/h and other different air volume. The higher the airflow, the better the exhaust effect, but it will also bring more noise and higher power consumption.
Operating steps
The following are the operating steps of the exhaust fan:
Install the exhaust fan in the location where it needs to exhaust, such as the kitchen wall or bathroom ceiling.
Connect the power cord of the exhaust fan to an electrical outlet.
Turn on the switch of the exhaust fan to start exhausting the air.
Clean the exhaust fan regularly to keep it working properly.
