Engineered for high-demand commercial applications, this Vacuum Motor delivers enhanced durability and cleaner performance.

Kent, OH — Bison®, a leader in innovative air-moving and power-transmission technologies, highlights the Lamb 6.6" Bypass Tangential Vacuum Motor, engineered to set new industry standards in durability, efficiency, and high performance. Purpose-built for demanding commercial and residential environments, this cutting-edge motor delivers superior power while achieving remarkable operational longevity.

The Lamb 6.6" Bypass Tangential Vacuum Motor is designed to reach sealed vacuums of up to 160" H₂O (40 kPa) or 170 CFM (289 m³/h), supporting a broad range of applications that demand uncompromising suction and reliability. Its innovative construction ensures increased efficiency and extended lifespans for brushes, bearings, and batteries.

Featuring a tangential bypass design, the vacuum motor separates working air from motor cooling air, providing cleaner airflow and consistent performance under heavy use. With both single- and two-stage fan options, engineers enjoy optimal airflow or vacuum according to their specific needs. It also boasts a compact motor design that significantly reduces noise and vibration, complemented by the option of a noise and carbon dust filter for sensitive environments.

Built for ultimate reliability, the Lamb 6.6" Vacuum Motor incorporates patented wet bearing protection and offers an Eternity brush option, significantly extending motor life. The newly developed fan system and advanced lamination technology yield industry-leading overall motor fan efficiencies, making the Lamb 6.6" powerful, long-lasting, and energy-efficient. This results in reduced downtime and maintenance, delivering tangible value for high-usage facilities that rely on sustained peak performance.

Illustrating the transformative impact of the Lamb 6.6" Bypass Tangential Vacuum Motor, Lindsay Manufacturing, a leader in central vacuum and commercial floorcare systems, partnered with Bison to find a solution for their most intense commercial environments. Working closely with Bison's engineering team, Lindsay introduced a custom version of the Lamb 6.6" Vacuum Motor into their VacuMaid® product line, achieving double the service life compared to previous solutions. The upgraded motor powers Lindsay's systems for up to three years of heavy use, while solving critical electrical interference issues in sensitive installations and streamlined maintenance with a new durable metal mounting bracket.
