Engine cooling fans designed for a spectrum of off-highway applications

Multi-Wing America’s core business is custom engineered engine cooling fans for Tier 4 compliance including a variety of applications such as off-highway equipment, power generation, oil and gas exploration, compressors, motor coach chassis, generators and construction equipment. Multi-Wing America’s low noise, high efficiency engine cooling fans are half the weight of steel, and their lower moment of inertia means reduced wear on fan drives.

Multi-Wing specializes in engine cooling fans, and our two most popular profiles, the sickle blade and the airfoil blade, can both be engineered into high efficiency, low noise engine cooling fans that will deliver high performance in the most challenging conditions.  The sickle’s large chord length and overall surface area also combine to generate greater pressure at slower speeds in an engine cooling fan. Multi-Wing’s airfoil blades provide uniform, high volume airflow with low power consumption for optimum efficiency. The airfoil’s twisted design reduces turbulence across the blade’s surface, resulting in low noise engine cooling fans.  Our airfoil and sickle series are widely used in engine cooling applications where requirements are more demanding. And with virtually zero blade deflection, 20 percent more static pressure and 5-7 percent more efficiency than standard airfoil blades, Multi-Wing’s new PressureMAX blade profile is specifically designed as a solution for Tier 4 cooling packages.

  • PressureMAX high pressure engine cooling fan
  • High airflow for Tier 4 heat rejection requirements
  • Used in compact envelope – common for engine cooling fans
  • Low noise engine cooling fans
  • High efficiency – reduced power consumption

Multi-Wing America’s engine cooling fans are available in glass reinforced polyamide (PAG), anti-static glass reinforced polyamide (PAGAS), and super tuff glass reinforced polyamide (PAGST). Multi-Wing America engine cooling fans have a diameter range of 8-84 inches and can be designed in configurations from 3 to 16 blades. Our engine cooling fans are available in the 2H, 3H, 4Z, 5Z, 5W, 6W, 7W and 9W blades in the airfoil series; the 6H and 6Z blades in our increasing arc series; the 1H, 4H, 1Z, 2Z, 7Z, 1W and 2W blades in our sickle series; and in the TR7Z in our true reversible series.

Multi-Wing’s engine cooling fans are the perfect solution for the high heat rejection requirements of Tier 4, because they provide high performance in the most rigorous conditions. And our low noise fans are a vital component in any hearing conservation program in accordance with the Occupational Safety & Health Administration’s (OSHA) Noise and Hearing Conservation Standards for workplace noise. Using our flexible design and system of standard interchangeable components, Multi-Wing can optimize virtually any air-moving solution.
