I installed this unit in my shop where my 3d printer requires a controlled environment...it's easy to set it...and forget it. It does move the air around and thats a good thing...I was worried about having to buy additional fans to move the air, but with this unit...no need. However, that does mean it puts out some noise. No more than you'd expect given it's performance. Solid construction, feels strong, not cheap. Easy to move around (on wheels).
