Polar Active Ice Cold Therapy System with 9 Quart Cooler is specially designed for post-surgery and drug-free pain relief. This FSA-approved Cold Therapy System uses a motorized pump to circulate cold water from the cooler to the desired body area, delivering localized cold therapy to users either at home or during hospital stays. The panel mount right angle coupling keeps the pump motor tighter to the cooler walls. This will stop the motor from flopping around in the cooler when emptying it.
