Centrifugal Blowers Double Inlet

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.

Blowers Range From : Impeller Diam. : 125 to 180 mm Air Flow : 200 to 2000 m3/hr. Input Voltage : 110, 220, 440 V AC (50/60 Hz.) Power Input : 60 to 350 W

NOTE : Motors with CE Mark and confirm to EN 60335-1 standards
