 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.

 

Blowers Range From :
Impeller Diam. : 125 to 240 mm
Air Flow : 175 to 1200 m3/hr.
Input Voltage : 110, 220, 440 V AC (50/60 Hz.)
Power Input : 20 to 350 W

Note : Motor used with CE Mark and confirms to EN 60335-1 standards.
