Aerus Central Vacuum Foam F...

Product details
Part 506B is a foam filter cut to 7 inches by 8.5 inches, listed for Electrolux and Aerus central vacuum power units. In the power unit it works after the dirt has been separated out, catching what the collection stage lets through before that air reaches the motor and leaves by the unit's exhaust.
Foam media like this fails gradually rather than all at once, so the usual sign is suction that fades a little at a time across every inlet in the house rather than dropping suddenly at one location. A foam filter that has gone stiff, matted, or grey has stopped moving air the way it should, and running the system on a spent filter puts extra load on the motor with every cleaning cycle.
- Fits: Electrolux and Aerus central vacuum systems using a 7 x 8.5 inch foam filter
- Construction: foam media, 7 inches by 8.5 inches
- Tip: rinse foam media in plain water and let it air-dry fully before putting it back in service; a filter that no longer springs back into shape after washing is due for replacement rather than another cleaning
Measure your existing filter against these dimensions before ordering, since Electrolux and Aerus have built central vacuum canisters in more than one filter size over the years.
