Key RivetTM blower wheels (also known as Fergas wheels) outperform competitors’ tab-lock design by using a unique “key rivet” manufacturing technique that results in a wheel which is lighter and five times stronger than those made by traditional tab-lock methods. The Key Rivet wheel, compared to a similar size tab-lock wheel, provides higher performance with a quieter and more efficient operation. Compare Key Rivet wheels with strip blower wheels. Key Rivet blower wheels are available in several diameters and widths.
