This Dual High Output Radiator Fan Assembly is part of the High Output Aluminum Shrouded Fans Series that is designed with the application in mind. Based on some of the most common Radiator core sizes sold today, this unit features an aluminum shroud measuring 28-1/4 inch wide by 17 inch top to bottom and is only 4 inch in overall depth to offer an adjustable yet precision fit. The natural, non-finished aluminum shroud gives the user the freedom to polish, anodize, paint, or simply leave it raw to create a truly custom look for an affordable price. The dual 13 inch high output electric fans are some of the most proven and reliable fans in their line-up. Offering a total of 4000 CFM, this dual electric fan assembly generates the most real-world airflow in the smallest package on the market.
