Drainvac SAC-20 Central Vac...
$59.99$44.99
Product details
This pack contains two Drainvac SAC-20 disposable, 3-ply cloth dust bags with a side-fill inlet for compatible 9-gallon (41 L) central vacuum units.
Will SAC-20 fit my vacuum?
SAC-20 does not fit every unit in the Pro2, G2 or Summum series. Drainvac’s compatibility information distinguishes:
- Summum and G2 units with two motors, built since May 2012.
- Pro2, G2, Summum and 2000 configurations with metal cages built before April 2012, single-motor configurations built between May 2012 and April 2014, and two-motor configurations built since May 2012.
Because the manufacturer groups several configurations together, check your model, motor count, cage and build date before ordering. For single-motor Pro2/G2/Summum units with a plastic cage built since April 2014, see SAC-32.

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.
