Hartzell Fiberglass Difference:

In the world of industrial ventilation, airflow is everything—and the fan wheel is its beating heart. Hartzell Air Movement, with over 145 years of expertise, has revolutionized this vital component on FRP fans with the industry’s only one-piece fiberglass fan wheel. The FA Wheel delivers unmatched strength, consistency, and reliability thanks to its seamless construction. By eliminating joints, reducing maintenance needs, and enhancing overall performance, Hartzell sets a new benchmark for FRP fan design.

The Only One-Piece Wheel in the Industry

Hartzell’s FA Wheel stands alone as the only fan wheel in the industry molded as a single, seamless unit. While competitors rely on bolted or welded joints, Hartzell uses a proprietary process that forms the wheel in one cohesive piece. This is made possible by designing and manufacturing its own molds in-house—ensuring total quality control and exacting standards for every wheel.

Think of it as precision casting with zero tolerance for error. Hartzell’s custom molds form the wheel’s complex geometry in a single operation, producing a high-performance component with no weak points. The result? A fan wheel that delivers identical quality and performance every time, giving facility managers confidence in long-term reliability.

Strength Through Seamless Construction

Industrial fan wheels endure intense forces—high speeds, heavy loads, and punishing environments. In multi-part wheels, every bolt and weld is a potential failure point. Over time, these joints can fatigue, crack, or corrode.

Hartzell eliminates those risks entirely. By molding the FA Wheel as one solid piece, it removes the structural vulnerabilities inherent in assembled designs. Even the aluminum hub is fully encased in fiberglass during the molding process, ensuring no metal is exposed to the airstream.

This seamless design delivers extraordinary durability. The FA Wheel is built to withstand years of continuous use in corrosive, high-impact environments—lasting up to ten times longer than traditional multi-part alternatives. It’s trusted across industries like chemical processing, pulp and paper, and water and wastewater treatment.

Precision Balancing for Superior Performance

Smooth, balanced operation is critical to fan longevity and efficiency. Many manufacturers balance wheels by drilling holes and adding bolts. But every hole is a vulnerability—an entry point for moisture, stress, and eventual failure.

Hartzell takes a smarter approach. The FA Wheel is balanced in two planes by removing material from molded sacrificial rings on the front and back plate with no compromise to the structural integrity of the wheel. After balancing, the surfaces are recoated to maintain full protection.

This precision method ensures zero compromise in structural integrity. The result: a fan wheel that runs quietly, efficiently, and reliably at high speeds—even in the most demanding conditions. It’s engineering you can hear… or rather, not hear.

Reduced Maintenance and Downtime

One of the biggest advantages of the one-piece design is the reduction in maintenance and unplanned downtime. Unlike multi-part wheels that require regular inspections and repairs due to joint wear and imbalances, the FA Wheel demands little intervention.

With fewer potential failure points and smoother operation, the FA Wheel extends the service life of the entire ventilation system. Facility managers benefit from lower total cost of ownership, improved uptime, and fewer headaches. Whether it’s a pulp and paper facility or a high-demand chemical processing system, Hartzell wheels keep operations running.

Optimized for Efficiency

Hartzell’s one-piece fiberglass wheel is engineered for performance on every front. Its airfoil-shaped blades minimize resistance, improving airflow while reducing energy consumption. The result? Lower power requirements, quieter operation, and increased system efficiency.

The design ensures that every wheel is aerodynamically consistent. Unlike multi-part wheels that can vary from unit to unit, Hartzell’s wheels are manufactured with complete uniformity. That reliability is critical in precision-dependent applications like wastewater treatment or controlled industrial processes.

For organizations focused on energy efficiency or meeting sound regulation standards, the FA Wheel delivers a meaningful edge.
