Vane Axial

Solid design of the blades permits medium to high pressure capability at good efficiencies. The most efficient fans of this type have airfoil blades. Blades are fixed or adjustable pitch types and the hub is usually greater than 50 percent of the fan tip diameter.
Applications - Primary applications include general heating, ventilating, and air conditioning systems in low, medium, and high pressure applications. Advantage where straight through flow and compact installation are required. Air distribution on downstream side is good. Also used in some industrial applications such as drying ovens, paint spray booths, and fume exhaust systems. Relatively more compact than comparable centrifugal type fans for the same duty.
