Calculating For Proper Ventilation

An essential aspect to any HVAC system is the CFM, otherwise known as “cubic feet per minute.” CFM is all about airflow. Too much airflow and you’ll have energy inefficiencies and varied levels of heating and cooling in a given area, putting a strain on your wallet when it comes to your energy bill. Conversely, too little airflow may cause it to take frustratingly long time to heat or cool a room. This also can lead to an increase on your energy bill.

That’s why it’s important to achieve that perfect medium between too much and too little airflow when you’re selecting the right fan or system for your facility. Thankfully, calculating the correct CFM doesn’t have to be difficult. Simply put, you take the length of the room and multiply it by the width and the height of the room. You take this number, then divide it by the minutes in the frequency of air change desired. You now have your required CFM.

It’s simple enough, but to ensure you’re calculating correctly, just input your data in our CFM calculating tool here. It will tell you exactly what type and size of fan(s) will work best in your given environment, so you know exactly what you’re looking for.
