Product Profile of Centrifugal Blowers - Double Inlet

Vbm enterprises manufactures centrifugal blowers - double inlet. Vbm enterprises offers external rotor motors, axial flow fans, centrifugal blowers, etc. Centrifugal blowers - double inlet normally use forward curved impellers made of galvanized steel, which are press fitted on the rotor of the external rotor motor, making the unit compact. The double inlet of these centrifugal blowers 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 long life. The assembly of the 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.

Centrifugal blowers - double inlet include:

• Impeller diameter: 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

Motors of the centrifugal blowers - double inlet come with ce mark and confirm to en 60335-1 standards.

Applications of centrifugal blowers - double inlet are:

• Fan coil units in hvac applications

• Applications with relatively high static pressure at the outlet and low noise

• Lift cabin applications
