Looked at the website and all I can say about it is bovine manure. It doe s not have 50% more cooling capacity. It is rated at 14,500 BTUH and others are rated at 15,000 BTUH, unless they are comparing it to a much smaller unit.
Next the manure about a single fan unit....it has two fans like they all require. One for the chilled air and one for the condenser air. Most units use a single, double ended fan motor. Our Coleman Mach 8 Plus has two separate fan motors.
The website is a lot of smoke and mirrors.
