KB650B & KB650S Thin Fans

The KB650B and KB650S are extremely compact thin fans delivering 210 CFM of airflow, engineered to fit into tight spaces where standard cooling solutions prove impractical. Their versatile mounting configurations allow them to function in either pressurization or exhaust mode, providing flexibility in system design and installation.

These units feature rugged construction with a durable baked powder finish that resists corrosion and wear in demanding industrial environments. Both permanent split capacitor and shaded pole motor options come equipped with UL/CSA Recognized motors and automatic-reset thermal overload protection, ensuring reliable operation and safeguarding against motor damage from thermal stress. The motor design incorporates low temperature rise characteristics and utilizes cooling from the blower's intake air to extend motor life and maintain consistent performance.

The KB650B and KB650S operate reliably across an exceptionally broad temperature range from minus 20 degrees Fahrenheit to 250 degrees Fahrenheit, thanks to special permanent lubricants formulated for extreme conditions. Both models include 12-inch minimum power and ground leads for simplified installation, and all motors carry UL Recognition with a Declaration of Conformity to applicable CE Standards. A complete line of accessories is available to support custom applications and system integration.
