Air-Flo Central Vacuums were produced by MD Vacuum as a private label for Central Vacuum Inc. in the greater Chicago area from the late 1970s through the early 1990s. These all-steel power units were available in a two-motor Air-Flo Model CFM2 or a three-motor Air-Flo CFM3 that provided excellent performance. Everything on this website is compatible with Air-Flo Central Vacuums.
The Air-Flo units contained Ametek quality motors and an extensive filtration system. In fact, many of these systems are still in operation today! The units were produced by MD Manufacturing until the late 1980's when an alternate manufacturer was located near Chicago. These later units had a two-tone paint that included a light brown color and clamps with which the motor module could be removed from the trash compartment.
A well-maintained Air-Flo Central Vacuum System should provide you with excellent cleaning performance, as well as 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 Air-Flo Central Vacuum System should make your job easier, giving you more time to do the things you prefer.
Air-Flo Central Vacuum Systems have historically used 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.
All Air-Flo Central Vacs empty from the top and use HyperFlow Replacement Bags. Air-Flo CFM2 uses Hyperflow Part #720H-5 Bags and the Air-Flo CFM3 uses uses Hyperflow Part #721H-5 Bags. There is also a secondary filter below the cloth bag which should be removed and cleaned approximately every five years.
Most Air-Flo units were sold with either a small TK2 air-driven power brush or no power brush at all, so upgrading to a new complete kit will greatly increase the performance of all Air-Flo systems.
