The Condux Power Dart Blower is a pneumatic rodding system especially suited for long duct runs. A three-motor system allows you to choose the correct pressure output for your needs. With all three motors engaged, the Power Dart Blower will deliver up to 300 cfm of air at 3 psi maximum pressure. This output would easily blow 1/2" poly line or pull tape over 2,000 feet in conduit up to 6 inches in diameter. The Dart Blower unit weighs only 31 pounds and operates at 110 Volts.
