Rear-Air is the economic answer to getting air conditioning or heat to the rear of any vehicle. Rear-Air is great for transportation vehicles that have a partition blocking off sufficient air circulation. Rear-Air is used by corrections, police and sheriff's transportation units, and tactical teams. Rear-Air can also be routed to vehicle trunks to cool mobile computer systems. Rear-Air is a great way to cool camper shells and dog crates in the back of truck beds too.
