Motors, Filters, and Maintenance for AirForce Central Vacuum
All Products for AirForce

Only hear a "click" when trying to start the system? Does it shut off and start back up in a few minutes? These are common signs of a dead motor which only leaves two options. Replace the motor or the replace unit. If you liked the amount of suction it originally had, then replace the motor. If you'd like stronger suction or if you'd like a cleaner disposal system consider a different unit or alternative brand.

How is a central vacuum maintained? Generally, the only thing required is emptying the main unit. Beyond that there are some upkeep and preventative options given below.
Filtration Maintenance
Much like a regular portable vacuum, the basic maintenance of a AirForce Central Vacuum System is changing the bag in the main unit. To do this, remove the top of the unit, remove the black gasket, if installed, then lift the paper bag and support bag out together, and place a paper bag into the trash can. Put a new paper filter into the support filter, wrapping the elastic over the edges. Set the filter into the vacuum putting it below the necks of the intakes. Some vacuums have a closed bag that slips off an elbow and a new bag is simply slid back on. Below the support filter is a mesh filter that keeps large debris out of the motors if there was an accident with the main filter. The AirForce Owner's Manual is available here and please note that over the years the look of the vacuum has changed.

Motor and Vacuum Maintenance
There is nothing to lube or oil in or on the central vacuum system, including the AirForce motor, AirForce vacuum motor unit, or AirForce vacuum cleaner. For the indoor vacuum brush, the fibers that get wrapped around the brush roll of the vacuum cleaner head should be cut out and removed on a regular basis.

Pipe and Hose Maintenance
We recommend cleaning out the hose and piping system at least once per year. The best way to do that is with Tornado Central Vacuum Maintenance Cloths. They do a couple of things. First, they push through the pipes, bringing along stalled out debris. Second, they deodorize the hose, pipes, and unit. Some amazing results can come from this product. The vacuum hose will last longer if it is stored on a hanger, always being detached from the vacuum after each use. See if any of these Storage Items can help your situation (scroll to the bottom of the Accessory Page).

Email Reminders to Empty Vacuum
Sign up for the Free Quarterly Email Reminders to dispose of your central vacuum debris. Let the trash build up can reduce suction, making the unit run hotter and clean less efficiently.

Replacement Motors and Parts for AirForce Vacuums

Troubleshooting
If the suction is not starting or not stopping and there is a Power Module or RF915 Receiver plugged in near the main unit, please give us a call. The AirForce vacuum communicates differently than all other central vacuums. Instead of a low voltage wire running from each inlet to the main vacuum, the signal is sent over the 110 volt system (Power Module), or through a radio frequency control (RF915). Please call us to help you with these issues. For general central vacuum issues use the Interactive Troubleshooting Guide and Solutions.

Motor Replacement
The AirForce Central Vacuum was unique. Please call us, the manufacturer, for help with the motor or technical issues.

Circuit Board, Relay, Transformer, MiniBreaker
Prior to 8/2004, AirForce units used a separate transformer, relay, and minibreaker. Since then, a circuit board is installed which houses all these electronics. The most common circuit board replacement for single motor AirForce vacuums is the Vacuum Motor Circuit Board for Single Motor Units 110 Volt. For other models with different voltage and two motors the replacement circuit boards are here. These robust boards are made by an industry supplier.

Motor Carbon Brush
The AirForce motor has two carbon brushes that wear down and can be replaced before they damage the motor. However, the AirForce motor may go bad for other reasons while the carbon brushes remain fine. AirForce motor brushes can be checked every few years and replaced if the 3/4-inch-long solid carbon is worn down. Definitely replace if one or both are down to 3/16 inch. Type the motor replacement number (not model number) in the search box and the motor brushes will come up along with instructions.
