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. Single inlet signifies that the Air is drawn from one
side of the Blower only. 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.
