Detailed comparison of the above garage exhaust fans
We will compare all the fans on their selected features to give you a better idea when looking for selected features on which you can base a buying decision.
Comparing Fans Regarding Rust Resistance
Rust resistance is a very important feature that will influence the life of a fan. Most exhaust fans are utilized to extract warm moist air from a building, and the excessive contact with moist air will cause rust of the blades of impellers if it’s fabricated from a material that rust easily. So let’s go and take a look at the selected fans for rust resistance.
|Fan Model Name||Rust Resistant?|
|QuietCool GA ES-1500||Yes|
|Broan – Nu Tone||Yes|
|Tru North Vent||Yes|
All of the specific fan manufacturers have taken care to ensure that the fan you will buy has a long lifespan. All fans in the selection have been made of materials that vary from Aluminum, Stainless Steel, Galvanized Steel, and plastic. None of these materials rusts easily, and the weakest of them is the galvanized steel. The galvanizing might work off over time, leaving only the steel that is prone to rust. However, this process might take from months to years to lay the steel barren.
Comparing Fan CFMs
Airflow rate (CFM) is a metric whereby the displacement or movement of air is measured. For instance, if we have a garage with measurements 20′ length with a width of 20′ and a height of 10′ (20X20X10=4000 Cub ft), We need to replace the total air volume in the garage every half an hour, so the total volume has to be displaced two times in an hour. Therefore we multiply the total volume of the garage by 2 (4000 X 2 =8000 Cub ft) of air that must be circulated in an hour. By dividing the 8000 Cub Ft by 60 min (8000/60 = 133 CFM) So for your garage, you will need a Fan with a CFM = 133 to circulate the air every half hour.
Here is a great guide to finding the right CFM for the fan for your garage: Garage exhaust fan size guide.
|Fan Name||Airflow Rate (Cubic Feet per Minute)|
|iLiving ILG85F||3368 CFM|
|AC Infinity||2418 CFM|
|QuietCool GA ES-1500||1452 CFM|
|Broan – Nu Tone||308 CFM|
|Tru North Vent||300 CFM|
The TRU North Vent fan has the lowest CFM, while the GRELWT has the most considerable CFM value. By using the measurements of your garage and how many times you want the air circulated in your garage, you can now do a calculation to ascertain which garage fan will work the best for you.
Comparing Fan Speed of Selected Fans
|Exhaust Fan Name||Fan Speed (RPM)|
|iLiving ILG85F||1075 RPM|
|QuietCool GA ES-1500||–|
|Broan – Nu Tone||–|
|Tru North Vent||–|
The iPower boasts the highest speed for the ones where speed is known, with the iLiving ILG85F, having the slowest speed. On the one hand, speed is an indication of effectiveness, but with an increase in speed, the noise levels can go up.
Comparing Fans On The Basis of Where They Are Installed
The position in which fans are installed is discussed in this section.
|Fan Name||Location Of Installation|
|QuietCool GA ES-1500||Wall, Ceiling|
|Broan – Nu Tone||Ceiling|
