Motors, Filters, and Maintenance for AirVac Central Vacuum
All Products for AirVac
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.

Basic Maintenance for AirVac Vacuum

Filtration Maintenance
Much like a regular portable vacuum, the basic maintenance of a AirVac Central Vacuum System is changing the bag, or, in most cases, emptying the dirt receptacle on the main unit. To do this, remove the base of the unit with a twist or by unlatching, then dump the debris. Place a plastic trash bag over the bottom of the unit. Reach up and grab the center weighted cloth filter and shake it. This filter can be further cleaned or replaced. To remove the filter, grab a side of it and pull toward the center. The outer stiff rim of the filter bends in and the filter drops out. To further clean the cloth or foam filters, wash and thoroughly air dry before installing. Note that on some units there was a small foam filter under the main filters that easily clogged. We recommend removing this filter permanently.

Motor and Vacuum Maintenance
There is nothing to lube or oil in or on the central vacuum system, including the AirVac motor, AirVac vacuum motor unit, or AirVac 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 AirVac Vacuums

Troubleshooting
Self diagnose your system using this Interactive Troubleshooting Guide and Solutions.

Motor Replacement
Contact a local dealer for service, or consider doing it yourself. Motors on the AirVac vacuum have a few fasteners and wires that need to be unattached, the reattached on the new motor. It should take less than one hour. First, turn off the circuit breaker or unplug the central vacuum unit. Then, access the motor by releasing the outer housing. Use the chart to find the right replacement motor for your AirVac motor model. A motor may have many numbers on it but typically the real motor number starts with 11. Here are detailed AirVac Motor Replacement Instructions.

Circuit Board, Relay, Transformer, MiniBreaker
Prior to 1996, AirVac 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 AirVac vacuums is the Vacuum Motor Circuit Board for Single Motor Units 110 Volt. The board is strong, yet generic, but will not work with units that have an electronic readout display on the front. There are other Generic Circuit Boards for units with different voltage and two motors. These robust generic boards are made by an industry supplier for most all brands.

Motor Carbon Brush
The AirVac motor has two carbon brushes that wear down and can be replaced before they damage the motor. However, the AirVac motor may go bad for other reasons while the carbon brushes remain fine. AirVac 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.
