Radial Blade Direct Drive Blowers
NIS-CO Radial Blade Direct Drive Blowers
APPLICATION:
Canada Blower Radial Blade Direct Drive Blowers are generally used on industrial applications for small exhaust systems where air is laden with dust or grit and also for supplying high pressure air for conveying and cooling. Canada Blower industrial blower can be designed in one of two configurations. Axial blowers, which are more easily recognizable to most people, feature curved ventilator blades that spin around a blower axis. The spinning motion of axial fan blades closely resembles the motion of the spinning hands on a clock. The curvature of the blower blades creates an imbalance of air pressure on either side of the fan. The difference in air pressure causes airflow. When the blades spin continuously, the blower airflow is continuous.
FEATURES:
Wheels
Constructed with straight radial blades of heavy cast aluminum for self cleaning feature, dynamically balanced and designed for efficient operation.
Housings
Arc-welded 16 gauge steel housings and motor bases for rigidity and long life.
Motors
Standard Radial Blade Direct Drive Blower units are furnished with open ball bearing, rigid mounted motors of either single phase capacitor-induction type or three phase induction type. Motors can also be furnished totally enclosed or explosion proof or with special current characteristics for special applications.
Rotation and Discharge - Radial Blade Direct Drive Blowers
Furnished for clockwise rotation, bottom horizontal discharge unless otherwise specified. At time of installation housings or wheels may be turned for other discharges and rotation if so desired.
Capacities
These Radial Blade Direct Drive Blowers are tested in accordance with test codes adopted by AMCA and the American Society of Heating, Refrigerating and Air Conditioning Engineers.
