From the product description, check product page for current description, price and availability:

• IP56 rated dust and water resistant 50,000 hour 34 CFM BLOWER (not a weak computer box fan like you will find in economy tower coolers)
• Professional 1A Power Supply with ON/OFF Switch and Extra Long 10 Foot Cord (not a cheap cell phone charger with a 3 foot cord, like you will find in economy tower coolers.) Costs Next to Nothing to Run
• Upgraded 1/2″ hose is the perfect diameter to supply a steady stream of cold air into the tower, and allow ample return air into the kegerator. Larger diameter hoses, like those used in economy tower coolers, restrict the flow of return air into the kegerator, resulting in inefficient cooling of the tower. We have done our research, and the 1/2″ hose coupled with our powerful blower will cool your beer tower better than any other tower cooler on the market!
• Factory Injection Molded Design Provides Durability and Protects Blower from Moisture and Icing
