How do I Adjust the Vacuum on the Foodsaver Compact II?

Mary McNally

The Foodsaver Compact II vacuum packages food to keep it fresh and prolong its shelf life in the freezer. You can also use it to vacuum-package silverware or other items to keep them dry while on the trail or camping. This kitchen appliance uses a vacuum to remove air from specially designed food bags or canisters. The gasket on the food canister ensures that a vacuum seal forms during the packaging process. The Foodsaver Compact II does not have an automatic vacuum adjusting button; however, there are tips to follow to keep the vacuum consistent.

Do not use generic plastic bags with the Foodsaver Compact II.
  1. Use only Ready-Made Foodsaver Compact II bags to ensure that a proper vacuum seal forms when using the Ready-Made Foodsaver Compact II. Line up all edges of the bag inside the vacuum channel so that the bag is completely inside the channel. Ensure that there are no folds or wrinkles in the bag.

  2. Inspect the bag's seal for wrinkles, cracks or tears; any of these problems can prevent a proper vacuum seal. Discard the bag and start over with a new one if its seal is damaged.

  3. Check the bag for leaks if a proper vacuum seal is still not forming. Seal the bag with some air still inside. Submerge it in a sink of water and press down on it. If bubbles form, there is a leak in the bag; discard the damaged bag and use a new bag.

  4. If you are using a canister instead of a bag to vacuum-pack your food, open the canister to expose the lid gasket. Check the food canister gasket to ensure that is has not come loose from the canister lid. Use a couple drops of rubber adhesive on the underside of the gasket if it has separated from the canister lid. Press the gasket back into place on the canister and let the adhesive dry completely.

  5. Wipe the gasket and the edge of the canister to remove any excess food. Let the surfaces dry. Leave at least 1 inch between the canister's top edge and the lid when filling the canister with food. Check the canister for surface cracks or scratches that could prevent an adequate vacuum seal from forming. Replace the canister if it is damaged.
