An air delivery system for a transport refrigeration unit having a dual speed prime mover, a compressor, a condenser, an evaporator, and first and second air delivery blowers for the condenser and evaporator, respectively. The speed of the first blower is directly proportional to the speed of the prime mover and the second blower is driven by an adjustable speed arrangement. The adjustable speed arrangement includes an electric clutch and a one-way clutch. The electric clutch, when energized, selects a predetermined speed of the evaporator blower, which is greater than the speed of the condenser blower, and when the electric clutch is deenergized the evaporator blower is driven at the same speed as the condenser blower, via the one-way clutch.
