320 to 920 CFM Quadruplex Centrifugal Blower Fans

Kooltronic Quadruplex Centrifugal Blowers move more air with greater efficiency and less noise than comparably-sized Double Centrifugal Blowers. The optimum wheel-width-to-diameter ratio and the specially-designed housings (which minimize inlet losses) combine for an exceptionally even distribution of airflow for maximum cooling. Quadruplex Centrifugal Blower Fans feature a unique design that isolates the drive motor and rotating components from the blower structure for smooth, quiet operation with minimum vibration. They are suitable wherever wide-band air movement is required, and are especially useful for applications such as cooling printed circuit boards and other components in densely packed electronic cabinets.
  • Airflow Capacities: 320 to 920 CFM
  • Extremely quiet, efficient operation
  • Full performance in any mounting position
  • Rugged construction with baked powder finish
  • UL/CSA ball-bearing motors
  • 12-inch [304.8] (minimum) power and ground leads
