Wall Mounted Air Curtain Fan - DuraSteel Aerial Titan-1 White 40 inch Air Door - Commercial Indoor Super Power Unit with Free Heavy Duty Door Limit Switch - UL Certified

Very quiet, smooth operation, easy to hang on the wall.Like another reviewer said, it has no instructions nor hardware nor wiring for the door switch. It appears the curtain is not even made for a door switch. Why include something that does not work with the unit?I suppose I could dismantle the entire unit and remove the power cord, then rig something up to connect to the switch but that is too much trouble. I just left it running all the time. If I had known the switch was useless I would have bought another brand,The instructions for mounting are poorly written by someone with a poor understanding of English.It would have gotten 5 stars if it had a way to hook up the switch.

Easy to install and convenient normal 120V plug. Only complaint is there is a 4 inch gap in the middle of the unit. This results in a lack of air production at that 4 inch gap all the way to the floor. This unfortunate design flaw lets flies/bugs in rather easily. I would not recommend if you are in an area with a lot of flying bugs.

This outperforms the Mars air curtains I replaced, at less than half the money, and with half the noise. I put two up for a 72" opening and started them on high. I could feel the blast of air over 12 feet away from the door. Even then the new air curtains were quieter than the old ones. I turned them to low and they still blew enough air to be felt more than 8 feet from the door! They were so quiet that after listening to the old ones, the cashiers could hardly tell they were on. Everybody happy! Me richer!

switch that is sent does not tie into the unit. It is made for a awoco and will tie into those. A little bit of false advertising. very unhappy

The product stopped working after two weeks.

This air curtain does a great job on high and decent job on low for keeping bugs out. It is very loud on high and somewhat loud on low. You cannot talk over the noise it makes on high so I usually end up closing the door and shutting it off if I need to have a conversation. On low it can be talked over, but is somewhat annoying. I would love this product if it was quieter.

They work great! Ordered 6 of them! Hope they last a long time! The magnetic switch is great!

have ordered this same product from vender in the past happy in the past and happy now the item performs well the order was quick and unit was at my door when promised two days
