Vaneaxial Adjustable Pitch Fans

Product Image

The Vaneaxial Adjustable Pitch Fans are designed and constructed for high-pressure applications found in heavy industrial-process applications such as air-assisted flares, combustion air, process supply, and exhaust. Adjustable pitch design conveniently allows for performance adjustments when the fan is at rest without the need for adjustable speed controllers or V-Belt drive systems. With eleven sizes, three hub ratios and both full and half solidity (number of blades) to choose between, the most efficient fan is easy to select using Fan to Size online.
