Fan Housing Only
For the thrifty DIY shoppers we also provide the Ninja Fan housing by itself. From here you'll need a power supply and a fan, purchase of the housing comes with a link to purchase both. The costs will be around $10 for the power supply and $25 for the fan. You will also want liquid electrical tape or similar for sealing the junctions in the 12v power cords.
The Ninja Fan press fits onto 1.5" PVC pipe, which is the standard size of air ports in traditional float tanks and float cabins. If your tank has a female 1.5" port you may select the option to add a short section of 1.5" PVC pipe, or if you have some extra pipe hanging around that will work the same.
