Blower Manual



Mainly consists of a dynamically balanced impeller located centrally in the bottom housing with very fine diametrical and face clearances. Impellers are directly mounted on the motor drive shaft. Both suction and pressure openings are located on the outer periphery of the Top and Bottom housing.


In the chambers set in the periphery of the impeller, air is accelerated due to centrifugal force created as the impeller turns, and is thrown into the side channels. It then flows into the next chamber, and is again similarly accelerated, thus continuously increasing compression as the impeller turns until it reaches the outlet port. The impeller rotates without contact with the inside of the housing, the compression space is free from oil and wear.


The blowers are supplied as a complete unit mounted with vertical flange mounted motor. Whilst installation it is recommended that the unit be properly bolted or fixed through foundation holes provided on the bottom housing of the blower. Connect the suction and pressure openings to your equipment or system by means of rigid or flexible piping or non-collapsible flexible pipe of suitable diameter. Electric supply to motor should be given through Star Delta connection with proper earthing and single phase preventor. Over load relay in the Star Delta should be set as per the rating of the motor or 0.5 to 1.0 amps more than current drawn during application according to rating of the motor. Direction of rotation should be as per the arrow marked on the motor or anticlockwise from top of motor. Ensure that the impeller rotates freely without any frictional noise. These blowers are meant for handling clean and dry air only. Recommended to provide vapor / liquid traps and suction filters between blower and your system. The blowers are designed for continuos rating but precautions to be taken during installation for better heat dissipation
