KOOLTRONIC Double Centrifugal Blowers are designed to provide greater airflow than the related single blower series, in the same types of low to moderate static pressure applications. Similarly, they are easily installed and operate with equal effectiveness in any mounting orientation. Eleven models comprise the series, offering a choice of sizes and capacities to satisfy a wide variety of cooling requirements. Together, single, and double centrifugal blowers are the backbone of forced convection air cooling.
