These Blowers normally use forward curved impellers made of galvanized
steel, which are press fitted on the Rotor of External Rotor Motor, making
the unit compact. Double Inlet signifies that the Air is drawn in from two
sides of the Blower and exited from one outlet. The Rotor with impeller is
dynamically Balanced in two planes, for vibration free running during its
entire life. The assembly of Motor and Impeller is essentially mounted in
a technically designed Housing for optimum performance. The External Rotor
Motor is cooled with the air stream flowing over it.
