History of Hoffman & Lamson

Hoffman™ and Lamson™, once individual brands of centrifugal blowers and exhausters, joined the Gardner Denver Inc. family in 2001 and 1996 respectively, as part of the Gardner Denver Nash Division. Since then, Lamson, established in 1880, and Hoffman, established in 1905, have combined their comprehensive lines of centrifugal blowers and industrial central vacuum solutions. The experienced Hoffman™ and Lamson™ team, backed by years of research and development, provides effective, affordable solutions for a variety of applications.
