Multi-Wing's D series features one-piece axial fans with high-pressure capabilities at low speeds, delivering high efficiency with low noise. Covering the diameters of 11.81 – 20 inches (300 – 508 mm), the D series represents relatively small-diameter axial fans, which makes them ideal for smaller heat exchanger applications, including oil coolers, air-cooled condensers and dry coolers. Due to glass-reinforced polyamide, they are also suitable for low-temperature evaporator applications.
The 8M fans feature injection-molded fan blades made of industrial-quality glass-reinforced polyamide (PAGI). The M series has 4 fixed-pitch broad paddle plastic blades in three standard pitch angles – 30°, 35° and 40°. The fans are only available in such a configuration where the blades rotate in a clockwise direction when facing the air stream and with broad paddle blade profiles.
