The VacMaster VP112S is a countertop chamber sealer sized for home kitchens: a 12-inch seal bar, a 12 × 11 × 5 inch chamber, a maintenance-free two-cylinder piston pump and a low lid that fits under most cabinets. It seals liquids that suction sealers can’t — but it weighs about 46 lb and its chamber limits bags to roughly 12 × 11 inches.

Key features
- Chamber design — air is removed from the whole chamber, so soups, marinades and brines stay in the bag.
- 12-inch seal bar and a 12 × 11 × 5 inch chamber.
- Two-cylinder piston pump — a dry pump, so there’s no oil to change (unlike the oil-pump VP215).
- Adjustable vacuum time (about 20–70 seconds) and seal time.
- Low profile — the hinged lid is designed to open under standard kitchen cabinets.
Who should consider it
Home cooks who seal liquids often, do a lot of sous vide with marinades, or want cheaper smooth chamber pouches — and have a permanent counter spot for a 46 lb machine.
How to seal a bag with the VP112S
- Place the filled chamber pouch in the chamber with its open end lying flat across the seal bar.
- Add filler plates if needed so the bag sits close to the seal bar height.
- Set vacuum time and seal time (start with the manual’s recommendations).
- Close the lid; the cycle starts automatically. Keep liquid-filled bags upright and don’t overfill.
- Check that the seal is clear and even across the full width.
Troubleshooting
- Poor vacuum: clean the lid gasket, check it isn’t cracked, and make sure nothing blocks the chamber seal.
- Weak or wrinkled seal: lay the bag flat and increase seal time slightly; clean the seal bar.
- Liquids boiling: warm liquids boil under vacuum — chill soups and marinades first and shorten the vacuum time.

- Dry piston pump — no oil changes
- Low lid fits under kitchen cabinets

Cons

Frequently asked questions
Does the VacMaster VP112S need oil?
No. It uses a two-cylinder piston pump that doesn’t require oil changes.
Can the VP112S seal soup?
Yes — as a chamber sealer it can seal liquids. Chill them first and keep the bag upright so it doesn’t spill as air returns.
Final recommendation
If you want a “real” chamber sealer that fits a home kitchen and never needs oil, the VP112S is a solid choice. If 46 lb is too much, look at the Anova Precision Chamber.
