Drainvac SAC-31 Central Vac...

$59.99$44.99

Product details

This pack contains two Drainvac SAC-31 disposable, 3-ply cloth dust bags for compatible 3.75-gallon (17 L) central vacuum canisters.

Will SAC-31 fit my vacuum?

Drainvac specifies this bag for Pro1 and S1000 series units built during either of these periods:

  • October 2011 through January 2014.
  • Since November 2014.

The series name alone is not enough to confirm fit. Units built outside these periods—including February through October 2014—need a separate compatibility check.

Product details

  • Part number: SAC-31 (Drainvac code SAC31).
  • Canister capacity: 3.75 gallon (17 L), as labeled by Drainvac.
  • Material: 3-ply cloth.
  • Included: 2 disposable dust bags.

Before you order

Match the bag code, inlet position and your unit’s configuration—not capacity alone. If your old bag is missing or you are unsure, contact our team with a photo of the model label and the inside of the canister, or call (888) 429-8828.

Replacing your bag

Turn off and disconnect power to the vacuum before opening the canister. Follow your unit’s manual to remove the used bag, seat the replacement securely on the inlet and close the canister. These bags are disposable; do not wash or reuse them. Check the bag regularly and replace it before it becomes overfilled.

Choosing between Drainvac bags

  • SAC-31: 3.75-gallon Pro1/S1000 units within the specified production dates.
  • SAC-32: 9-gallon, single-motor Pro2/G2/Summum units with a plastic cage, built since April 2014.
  • SAC-20: selected 9-gallon older or twin-motor configurations; check cage type and production date.

These are different fitments, not interchangeable bag upgrades.
