## Description

Product description 20 INCH SHUTTER EXHAUST FAN

Review: Works very well in barn - Works wonderful in our barn. It is very powerful! You can feel it move the air. It is also quiet.
Review: Fits 10 x 12 Harbor Freight Greenhouse... barely. - Originally bought a 14" exhaust fan. Simply was not big enough for 10 x 12 harbor freight greenhouse. I bought the 20.6 x 20.8 inch shutter exhaust fan not certain it would fit. It just fit between the aluminum framing on our 10 x 12 harbor freight greenhouse. I actually like how it fits. I used some left over 1" aluminum angle stock and stainless-steel bolts to attach it. Also used silicon to seal around it. Very sturdy installation. Greenhouse is reinforced with 2x4's and 4x4's. Not sure I would install this fan without some type of reinforcement. With 50% shade cloth, this fan was able to keep the greenhouse below 100 deg F during hot days of Michigan summer. We bought the temperature controller separate. As other reviewers have indicated, the plastic coating on the louvers is pretty much permanent. I would not recommend attempting to remove it. The coating does not affect function and the blue color doesn't bother me a bit.

## Questions & Answers

**Q: Does it comes with the thermostat?**
A: no

**Q: I was thinking about using this fan as an exhaust for my welder. Would this be a good idea?**
A: Like how?  It will clear out a small room or shed. There wouldn’t be any flammable fumes from welding like painting.

**Q: Why does the 20" have a higher cfm rating than the 24"?  makes me think all the numbers are garbage...**
A: Physics. The tipping point on power input to output... At a certain level the size of the blades will slow the CFM at the same amps because a larger mass requires more energy to move the same rotation distance.

**Q: How loud is the fan?**
A: If mounted solidly it seems relatively quiet.  As I am using it to help cool a running generator this really is a moot answer.

### ⭐⭐⭐⭐ Why?
*by A***C on July 23, 2023*

It came in yesterday, ad I got right to it. Install was easy enough. It works just fine and moves a lot of air. The blue film on the louvers was difficult to remove and resulted in bending some of them. Otherwise, it would have been 5 stars.
