Rotron Radial Blowers are unusually small and compact in design. They are available in CW or CCW, and in either simplex or duplex models. Duplex Blowers simplify ductwork and allow for greater volume performance in tight locations. Models are available for AC or DC power. Radial Blowers come in a variety of voltages and frequencies and are available with a variety of inlet and outlet configurations. Most units are available with an optional internal Fan Performance Sensor (FPS) or external Low Speed Warning Device (LSWD). Radial blade blowers produce a higher pressure-to-volume ratio at higher speeds than is obtainable from the centrifugal blower. it particularly suitable for cooling tightly packaged airborne electronic equipment and ventilating NBC protection system filters and particle separators.
