KBB49 Single Centrifugal Blowers

The KBB49 is a single centrifugal blower delivering 425 CFM of airflow, engineered to perform reliably in any mounting orientation for maximum installation flexibility in industrial cooling and climate control systems. Its rugged construction features a durable baked powder finish that resists corrosion and wear, ensuring long-term durability in demanding environments.

This blower is equipped with UL/CSA Recognized ball-bearing motors available in both permanent split capacitor and shaded pole configurations, each incorporating automatic-reset thermal overload protection to safeguard against motor damage from excessive heat. The motors are specifically designed for low temperature rise, with cooling air drawn directly from the blower's intake to maintain optimal operating temperatures and extend motor service life. All motors carry a Declaration of Conformity to applicable CE Standards for international regulatory compliance.

The KBB49 features special permanent lubricants formulated to perform across a broad temperature range from minus 20 degrees Fahrenheit to 250 degrees Fahrenheit, making it suitable for both extreme cold and high-temperature applications. Extended 12-inch power and ground leads provide flexible routing and connection options during installation, reducing the need for additional wiring materials.
