An air blowing apparatus has a primary fan housing, primary air fan and primary output combined with a secondary fan housing, secondary air fan and secondary output generating multiple airflows with distinct fluid dynamic characteristics. The primary air fan and secondary air fan can be powered by any suitable prime mover, including an electric motor, a pneumatic motor, a hydraulic motor, a combustion engine, and others. The secondary housing, fan and output can generate a secondary airflow having a different fluid dynamic characteristic than provided by the primary housing, fan and output. In aspects of the disclosed embodiments, the secondary airflow can have a relatively high air speed, and the primary airflow can have a relatively high air volume.
