The Truflo SDS39 molded fan from Phillips & Temro Industries (Eden Prairie, MN) is a one-piece, fully molded fan for engines in the off-road and power generation markets. With a diameter range of 500 mm to 990 mm (19.7 in to 38.9 in), the company claims the SDS39 is one of the world’s largest one-piece, fully molded fans for engines in those respective markets. In addition to being 26% more efficient than other molded fans, the Truflo SDS39 makes less noise, is lighter—and with lower power consumption, less need for attenuation materials and elimination of a clutch, is more affordable, according to the company. The Truflo SDS39 molded fan is available in any fan-mounting pattern, including fitment to viscous clutch. Other specifications include standard and reverse flow, glass-filled polyamide sickle-shaped blades, a steel center disk and optional shaft adaptors for direct, electrical or hydraulic drives.
