Blowbox TWIN Component Package


Out of stock


My newest tailgating rig: Blowbox TWIN mounted on an inexpensive 30 QT wheeled Igloo cooler (w/optional temp readouts and battery box countersunk)

My most popular model!

The Frankencooler Blowbox Twin is a revolutionary, compact design that can be used independently with any soft-sided cooler or lightly modified (drill 2 small holes) hard-sided cooler for hours of relief from blistering temperatures.

This cooler does everything the original Frankencooler does, only better – Faster, easier assembly, 95% complete, total separation of incoming hot air from ice/water, more ice capacity (no insulated divider or radiators taking space in your ice chest), and the small blower unit can be used remotely up to 4 ‘ away from the ice chest if needed. This design produces the coldest temperature differentials I’ve tested.

Airplane owners: These commonly available 4″ soft ducts can be used in place of the supplied aluminum ducts to route and deliver air anywhere in your cabin. No hardware needed, the spring coils are held tightly in place by the fluted plastic adapters.

Our most complete dual blower package, requiring only a few inexpensive supplies from Home Depot/Lowes to finish (screws, wire & connectors, silicone). Most individuals with average mechanical aptitude can complete this project in an afternoon.

Compare the Blowbox Twin to any purpose-built cooler AC on the planet – none can match its temperature differential, air velocity, variable speed, size, and versatility. My customers include numerous pilots including several small charter airlines, pet delivery companies, private investigators, long-haul truckers, classic car owners, art fair artists, sports families, campers, fishers, and others.

The Blowbox Twin comes with a 12′ corded 12V power plug, but for cooling anywhere, the included battery box will accommodate any of our ultra-high-quality lithium iron phosphate power cells for up to 10+ hours of cooling off the grid.

IMPORTANT NOTE: I am now drilling all case holes with the exception of small battery box mounting holes at top of the case as some individuals choose not to mount the battery box as they exclusively power the unit from the included 12V power plug.
