Is higher CFM better for airflow?
A: Airflow quantifies the amount of air a ceiling fan delivers and is measured in CFM which stands for cubic feet per minute. CFM measurements are taken when a fan is on high speed, then that number is divided by the watts used. This means that the higher the CFM, the more efficient the fan, and the more air it moves.
How big of a CFM fan do I need?
Choose a fan that can ventilate at least 1 CFM per square foot of room. So, for an 80 square foot bathroom, select an 80 CFM fan. For bathrooms 50 square feet and smaller, it’s recommended you purchase a bath fan designed for small rooms. In other words, choose under 79 CFM bath fans.

Does higher CFM mean better cooling?
Cubic Feet per Minute – or CFM – determines the amount of air that a fan can move through a room while operating at the highest speed. The larger the space, the higher the fan CFM must be in order to efficiently cool a room. CFM for fans is a critical measurement for determining if a room can be cooled.
What is the highest CFM fan?
The most powerful box fan available is the Lasko 3723 which has 2500 CFM.
How many CFM is 100 square feet?
If you only need the air changed 1 time per hour (ACH = 1), then just . 135 CFM is needed per square foot of space. So, a 100 square foot room would need 13.5 CFM. A 1,000 square foot room would need 135 CFM.
How many CFM do I need calculator?
Start with the total volume of air (in cubic feet), divide by the exchange rate (how quickly you want to replace the air), and the result is the total CFM you need for your system. Keep in mind that many applications (especially large areas) use more than one fan/blower.
How many CFM do I need for 120 square feet?
For example, for a room that’s 120 square feet and has a 10-foot ceiling: 120 x 10 = 1,200. 1,200 divided by 60 = 20. 20 x 8 = 160 CFM.
Which is best fan or air cooler?
Between these two, it is quite obvious that an air cooler provides much better cooling than a fan because it actually emits out cool air and not just circulate the air around. Also, while a fan covers a limited area of the room, air cooler uniformly distributes the cool air all over the room.

DOES CFM matter for fans?
CFM is everything… the more air you can move the better the thermal dissipation, having said that a compromise can be achieved by getting high CFM fans and running them at lower rpm to reduce noise which can equate to more air than a quiet fan with equal or less noise…
