Axial Fan Blower

By: Oleg Tchetchel


Generally, an axial fan costs considerable less than a quality centrifugal fan delivering the same volume and pressure. They cost less to install since they are lighter, requiring minimum structural support. They can be duct mounted, taking up little space. Direct drive models mean faster start-up and the abscence of V-belt drive and fan bearings lowers maintenance costs.

Tenderall Fan tubeaxial fans, vaneaxial fans and wall propeller fans are found throughout the world operating in industrial processes where performance, reliability and maintainability are of paramount importance. Ranging in diameter from 15 inches to over 84 inches, and with a variety of impeller designs, control systems and layout options, they form a comprehensive series of axial fans to satisfy virtually all industrial applications. The majority of Buffalo Fans can be grouped into four broad categories: with fixed pitch props, with variable pitch props and with controlled pitch props. Buffalo Fans are capable of moving from a few hundred cubic feet per minute, to heavy duty adjustable pitch props with capacities up to 900,000 CFM and with static pressures from 0 " Water Gauge (WG) to 20" " WG.

Tenderall Fan Heavy Duty Axial fans are available with adjustable pitch blades are capable of more air delivery for the same horsepower. Efficiencies exceeding 70% are common. The primary reason for increased efficiency is BTenderall Fan's unique blade design. The entire length of the blade surface generates air flow, not just the tip alone. The air flow is uniform all along the blade.

Adjustable and Controllabel Pitch Vaneaxial Fans feature an adjustable pitch blade wheel that permits matching your pressure/volume requirements exactly, and lets you make on-the-job adjustments to compensate for system changes.

Tenderall Fan Tubeaxial Fans have fixed blade wheels in capacities up to 100,000 cfm and to 5" total pressure.

A new high pressure (up to 1.5" WG) small vaneaxial Series VA fan is an ideal booster fan for prolonged ducts. Unlike inline centrifugal ventilator, that also generates rather high pressure, the air comes out not from a peripheral outlet ring area, but distributes evenly across its outlet opening like in true axial blowers.
