Spal USA has introduced AP90 High Output (H. O.) Series electric cooling fans to improve airflow in high-static pressure applications including diesel trucks, racing, off-road vehicles, and buses. A good example of a high-static pressure scenario is diesel pickup trucks. High airflow rates are required to cool not only the radiator, but also the charge air cooler, A/C condenser, and oil coolers. The AP90 H. O. Series fans are available in 11-inch, 12-inch, and 16-inch sizes. Throughout 2008, SPAL USA will introduce additional H. O. Series fans.
