I show how easy it is to duct airflow from the Blowbox TWIN using inexpensive 4″ soft ducts. This is especially handy for small planes where placing the unit and ice supply in the cargo area is often desired. My wireless remote and these soft ducts offer a great way to cool the cockpit area where space is at a premium.
The first Frankencooler Blowbox with Ryobi 18-volt power. 50-degree temperature differential in 100 + degree temperatures – only air conditioning comes close!
Note: Even the larger Ryobi batteries are only good for around 2 hrs runtime when powering dual blower coolers so you’ll need multiple batteries for longer runtimes.
First Blowbox TWIN powered by a Ryobi 18V lithium battery. It was way too windy to test outdoors. The temperature in the garage was 87 degrees, outflow temps were low 30s 🙂
