Squirrel cage blowers can have forward swept or backward swept blades or straight (axial) blades, but the airflow direction through the blower is the same regardless. So if you have a backward swept design and run it in reverse, the air flow looks the same, but with less flow and/or static pressure.
Are squirrel cage fans explosion proof?
The 3-phase, squirrel-cage, explosion-proof induction motor cutaway supports industrial training activities related to electric motor types, as well as repair and troubleshooting. An integral horsepower, industrial-duty motor is modified for training purposes.
