Why Our 4” Inline Duct Fans Are the Right Choice For You 

There are a few reasons our customers end up choosing us in the end when it comes to 4” duct fans. Our latest generation features EC motors and dual jet type impellers to deliver up to 141 CFM while taking just 21 watts. That combination of power and efficiency can’t be beaten. Better yet, the fan is quiet, especially when run at low to mid speeds - keeping your grow discreet. Other fans are noisy and disturb you while you try and relax in another room - these will not. 

But that’s not all - it’s also easy to dial the fan back to save even more energy when ventilation needs are lower. As your plants grow bigger or as temperatures increase over the course of the growing season, you can speed things up to keep the climate right where it needs to be. And, through the compact design of our 4” duct fan, you can save space allowing more room for your plants. As a hobby grower, space is something you may not have a lot of - so optimizing your grow equipment accordingly is essential.
