Blade Design

Rite-Hite HVLS Fans construct its blades from strong, lightweight aluminum. This produces a more stable blade that maximizes air movement directly underneath the fan. In addition, Rite-Hite fan blades have an advanced, contoured shape (tilt, taper and twist) that produces consistent airflow across the entire length of the blade. This unique fan blade design produces the most air, over the largest area, at the lowest cost when compared to competitive HVLS fans.

Hub and Mounting System

Similar to the blades of a helicopter, Rite-Hite’s fan blades are attached to the hub by a pivot. The pivot is surrounded by a resilient, vibration-absorbing material, which eases the stress transferred to the hub and drive during operation. When compared to fans with rigidly- mounted blades, Rite-Hite blades can reduce stress to the hub and drive by upwards of 50 percent, which substantially increases the life of the drive mechanism.

To ensure a tight connection, Rite-Hite fan blades are mounted in two specific ways. They are seated on the hub arm and then locked into position with a machined bolt that requires a torque setting. In addition, all Rite-Hite hubs and blades are “rotationally-balanced” at the factory and will never require adjustment. This ensures smooth and balanced operation over the lifetime of the fan.

Most HVLS fan manufacturers use a cast hub, which is created by pouring molten aluminum into a mold. It is difficult to regulate the consistency of a casting due to variances in the materials and manufacturing process. As a result, cast hubs are more porous and susceptible to cracking. Rite-Hite uses a milled aluminum hub that is much stronger than a traditional cast hub. A computer controlled milling machine is used to remove materials from a block of aluminum. This process produces a more durable and reliable hub when compared to a cast hub.


The Revolution HVLS Fan offers a three-way motor-to hub safety connection. The hub attaches to the motor using a reverse thread bolt and tapered aluminum bushing, a safety ring backs up the motor to hub connection, and finally, each blade arm is attached to the safety ring. These three features, working together, help to ensure the safety of people underneath and around the fan.
