The AirVac Central Vacuum brand was formed by Nortek after it had purchased M&S Systems (Music and Sound) in 1982 and Filtex in the early 1990s. It was a logical compliment for Nortek's intercom business. Linear bought out Nortek in 2004 and continued to produce AirVac Central Vacuums. Linear officially discontinued producing central vacuums in November 2014.
For a period of time, they offered the original, metal constructed, M&S AirVac Central Vacuum and the M&S Filtex Built-in Vacuum. Nortek eventually created a new central vacuum with two distinct plastic models, the AirVac "Red Series" that operated with an inverted weighted cloth bag, and the AirVac "Platinum Series" (Blue) featuring a disposable paper bag located inside the housing above the bottom.
A well-maintained AirVac Central Vacuum System should provide you with excellent cleaning performance as well as healthy allergy relief. All debris that is picked up is deposited out of your living area, including those fine dust particles commonly emitted from portable vacuums. The convenience of a central vacuum system should make your job easier, giving you more time to do the things you prefer.
AIRVAC has historically utilized all components that are compatible with the rest of the industry, including their pipe and fittings, inlets, motors, circuit boards, hoses, attachments, and power brushes. Any exception will be identified in notes found in secondary product pages.
The Filtex AirVac Central Vacs used a top-entry disposable paper-bag, while the original M&S AirVac used a cylindrical foam filter. The Red Series operated with an inverted weighted cloth bag which requires you to shake it out each time you empty the power unit.
For a period of time, AirVac was used as a private label under the name Chamberlain, for a garage door company.
