DuraSteelWall Mounted Air Curtain Fan - White 60 Inch Air Door - UL Certified Commercial Super Power Indoor Over Door Fan with Heavy Duty Door Limit Switch Aerial Titan-1

My reason for purchasing this unit is to keep flies out of the house. The air curtain came in the original box with another box over the outside. I bought the unit "Used good condition" from amazon and the unit was in good condition but missing the switch. Amazon support does not have an option for having a missing part sent but does have an option to return it for a refund but I chose to keep the unit as it is fully functional and the total price for including shipping was just under $139 thus I felt this was a great value buy. I placed the unit in my garage door just outside my kitchen and there was an outlet in my garage that was reasonably close to power the unit. I ordered this Gagalor2 Sets NO&NC Magnetic Switch Door Contact Sensor Surface Mounted from Amazon for $8.37 including tax. Link to magnetic switch: https://www.amazon.com/gp/product/B0BMFZQK6T/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 The magnetic switch mounting and wire connection was fairly simple and straight forward. You simply divide the yellow wire and connect the ends to the common and N.O. leads. When the door opens, the unit then powers on. It took about an hour to install the unit, mount and wire the magnetic switch. As expected there is a small time lag of approximately 1 second before there is a sufficient air flow when the door is opened. There is also a gap of 4 inches in the middle of the fan that has no or minimal air flow. Between the small gap and the time lag of powering the unit, it is not 100% efficient in keeping flies out of the house but it is certainly better than before. I suppose the efficiency would improve if the door is cracked open 1" to activate the circuit before fully opening the door but I don't always remember to do this, especially if I am in a hurry. My wife and kids would never do this so I chose not to even try to instruct them to pause 1 second before fully opening the door. It is my opinion that the small gap in the middle with the lack of air flow is less of a problem than the extension lag but I have no real proof. Overall I'm very pleased with the product as the mounting wasn't too difficult but would recommend placing new holes in the bracket to mount to a stud or two. I would recommend this unit. Be sure you have sufficient clearance above the door for the unit.

Appears to be well-built and operates well. You can tell it's an equality machine. The switch is separately made in China, and although one of the parts wasn't included (the long screw), I ended up using my own anyway. Otherwise, the switch itself seems to have pretty decent quality components as well. For mounting, it took 20 minutes, and another 15 minutes for the switch, including figuring out where to place it. The switch has a normally closed and normally open option, so you can have it set up so that if you want it on when something's closed or you want it off when something's open, or the reverse when something's open. If you want it closed or normally open (i.e., when you want your fans to operate), those options are all within the switch.Plenty of air movement set to low on high. It is noticeably higher; however, once inside the house, you can barely tell, but it certainly seems to operate. This is about 8 and a 1/2 feet in the air and hits the ground pretty hard with air.

Good quality, made well, easy to install and simple to operate, it simply creates air curtain and I installed on garage door to keep insect out, it works very well, I recommend it. The only issue I have is the noise, it is noisy especially when running on high, but not significant problem

We love it!! Works great! Easy to install!

Used a lot of electricity.

Works great. Waiting to see if it minimizes bugs getting in the house

The media could not be loaded. Installation was a cinch. Everything was included in the package. The unit is a bit heavy so you'll want help getting it mounted, but once it's up, it's sturdy and reliable.We've had it going for about a week now, and we've seen a huge impact on the number of flies that get into the house.

First product I have reviewed in a long time. I would give it more than 5 stars. Have horses and flys- this keeps the flys out. It also keeps the heat inside(the house is noticeably warmer). Others have complained about noise. The powerful rush of air is music to my ears- saving us money and hanging up the fly swatter for good. I looked at other units at a restaurant supply store costing double the price and the build quality of this unit is much better. Love the matte black and the instructions were top notch. I had to run wire and an outlet for it in the attic- it was well worth it. Looking forward to the summer to keep the house cool and to see a reduction in our energy bill. I really think every home should have one of these and this brand is exceptional (from it’s packaging to operation).
