Schaefer VK8 Versa-Kool Air Circulator Fan, Ceiling Wall Mount Greenhouse Fan & Steel Guards, 450 CFM, 1/100 hp, Energy-Efficient Commercial Fan for Patio, Garage, Industrial & Workshop (White)

We purchased this for our greenhouse. I love the fact that it is on all the time when plugged in. We got a thermal switch to attach to it and now when it reaches the set temp, it sends power to the fan and it is on! We never have to tend to it. I highly recommend this for a greenhouse.

This fan is easy to install and can be adjusted to about any angle.. I have it mounted in my 8' x 12' greenhouse and it works great. It should last for many years running 24/7. I highly recommend this product.

Moves air in the greenhouse and it’s quiet

So the fan moved and dispersed a lot of air in a rather quiet fashion, but the way its built caused 1 of 2 units to dismantle during shipping. The prop blades loosened and fell off the shaft and the unit is built to prevent people from opening it so I was unable to put it back on and tighten it. This gave me concern regarding the blades on the other unit I purchased so I returned both.

Nice quiet fan, although I like the fan, it was not big enough for my greenhouse needs. I need something bigger (my fault)! Does not seem to push a lot of air.

My original one ran continuously in humid greenhouse for over 10 years before needing replacement! This is the only brand of greenhouse fan I will ever use! Literally no upkeep at all!

I have several of these in multiple livestock buildings. They have been running for 4+ years without shutting off. Very efficient and quiet.

Good enough that I bought a second to compliment it in my greenhouse 8x12x8. A very small amount of bearing noise, etc. fan is quiet and puts off very nice feeling air. Not too choppy, very smooth. The L-bend bracket is somewhat versatile for mounting the fan. Horizontal mounting only, less than 45 degrees up or down. The bearings are meant to be horizontal, and have oil ports for service, I believe.
