Review on UL Certified 120V Unheated Awoco 48 Super Power 2 Speeds 1650CFM Commercial Indoor Air Curtain With Free Door Switch by Michael Hemmig

We were very impressed on how powerful it was when we first turned it on. It's great to also have 2 different speeds to choose from with the High/Off/Low switch. Included door micro switch with roller plunger, and has a dedicated wire for the switch. All we had to do was simply extend the wire and connect it to the switch. Installed the mounting plate first, then hung up the air curtain. It was a very easy procedure right out of the box. It has done a great job keeping out the bugs and hot air!
