For 45 years, the DEMARCO® name has been synonymous with the industrial vacuum industry focusing on new revolutionary patented technology. This vibrant history and commitment to excellence matches the ongoing manufacturing innovations of our high quality and high performance DEMARCO® Industrial Vacuum Systems. Founder, Thomas M. DeMarco's first patented industrial vacuum invention in 1968 incorporated the now outdated bag-type filter technology, which over 40 years later, is still being used today on competitor systems with either a manual shake or continuous air-pulse jet cleaning method. However, in 1986, maintaining the company’s innovative history, Thomas introduced and utilized pleated cartridge filter technology in his newly patented line of MAX VAC® Industrial Vacuums. This pivotal innovation changed the course of history in the vacuuming industry. This rich company history of service and patented technologies are hallmarks for DEMARCO® Industrial Vacuum Systems, whose reputation is backed by the DEMARCO® team of engineers and technicians. They maintain their legacy as the leading innovator of industrial vacuum applications with their knowledge, designs, and engineering expertise. DEMARCO® is always ready to help and to answer questions about your vacuum needs. Vacuums Built For Industry™
