JUNair is a UK based company that are the inventors and patent holders of the QADS auxiliary air movement system for the faster curing of waterborne paints. 

They are also the inventor of Smart air, a mini, portable prep station used for small repairs almost anywhere in the shop.  

JUNair QADS are the original auxiliary air movement system that was developed through research.  All other corner mounted blower systems are really copies forced to work around JUNair patents.  Due to the patent that they hold they are the only company able to take air from above the filter in the plenum where it is hottest and redistribute it to the lower portion of the cabin reducing temperature stratification.  Unlike the copies that must mount small inadequate sized motors inside the booth cabin, JUNair mounts its 1.5 hp motors on the roof.  This is one of the reasons JUNair QADS have the fastest curing times and are installed in most paint company training facilities.  On a hot humid day Genuine JUNair QADS really make a difference.
