Trovac 3-Notch Central Vacu...
$6.99
Product details
Part TFASS004 is the collar a disposable filter bag clips onto inside a central vacuum canister, formed with three notches so it keys to bags cut for a 3-notch mount. Getting the notch count right is what keeps a bag seated and sealed rather than slipping loose during use.
A bag that will not lock down, or one that leaks dust around its collar even when it looks properly seated, is more often forced onto the wrong notch pattern than actually defective. The adapter itself wears with repeated bag changes too, and enough cycles can round over the notches until even the correct bag no longer clicks into place.
- Part: TFASS004
- Notches: 3
- Function: mounts a disposable filter bag to the canister intake
Confirm your replacement bags carry the 3-notch style before buying, since 2-notch and 3-notch adapters do not cross over. A small part, but the wrong one leaves every bag leaking from day one. Fitting the replacement is a tool-free push into the canister's bag mount, so once the notch count is confirmed the swap itself takes only a few seconds.
