A benchtop chamber vacuum sealer for meat, fish, marinades, sauces and anything else with liquid in it. The bag sits inside a 355 × 340 mm chamber, the lid closes, the pump pulls the whole chamber down to −100 kPa and a 320 mm bar seals the bag before the air comes back. Stainless case, adjustable cooling time, emergency stop, and it runs at 70 decibels or less.

Set it on a level bench with clear space around it for ventilation and plug in. Run one empty cycle before the first bag.
A suction sealer pulls liquid into the seal and fails. A chamber sealer pulls the air out of the whole box, so wet food packs like dry.
The bag lies flat inside the chamber with its open end across the seal bar. Close the lid and the pump draws the chamber and the bag down together, so nothing is sucked out of the bag because there is no pressure difference across it. Marinades, stocks, sous vide bags with butter in them, a whole tray of portioned mince: all of it seals cleanly, and the vacuum reaches −100 kPa rather than the −60 or so a countertop suction machine manages.
It is a 27.6 kg stainless box with a pump in it, and it behaves like one. The cooling time is adjustable so the seal sets before the lid lifts, and there is an emergency stop and start on the panel. Under 70 decibels, which is quiet for a machine with a pump in it.
What this usually leaves the warehouse with.

The chamber is 355 by 340 mm and 70 mm deep, which takes a 250 by 350 bag with room for a full steak, a portion of fish or a bag of stock lying flat. Because the whole chamber evacuates, the bag can be any thickness of chamber bag rather than the embossed kind a suction sealer needs.

The cooling time after the seal is adjustable, so the weld hardens before the chamber refills and the seam does not stretch. A pressure bar over the seal keeps the bag flat while the wire does its work, and an emergency stop opens the chamber mid-cycle.

Stainless case, oil-lubricated vacuum pump, a 320 W seal bar. It comes with a spare heating wire, a roll of high-temperature tape for the bar, a filler plate to raise thin bags to the seal, and a bottle of pump oil. Those are the consumables, and they are in the box.
Vacuum is measured relative to the room. A countertop suction sealer typically manages somewhere around −60 kPa before liquid reaches the seal.
The benchtop model is the one to buy for a kitchen bench. The freestanding version is listed when back in stock.

Ready to use out of the box.
Yes, that is the point of a chamber machine. The bag and the chamber are evacuated together, so nothing is drawn out of the bag. Stock, marinade, soup and sauces all seal cleanly. Leave a little headroom in the bag and let hot liquids cool first.
Plain chamber bags, up to 320 mm wide and about 350 mm long to fit the chamber. It does not need the embossed bags a suction sealer uses.
It depends on the bag and the setting. The cooling time is adjustable, and a bag of dry goods needs less time than one full of stock.
It is an oil-lubricated pump, and a bottle of oil is in the box. Check and change the oil as the manual describes, and replace the heating wire or tape when the seal looks uneven; spares of both are included.
A standard power point. The motor peaks at 1700 W at the start of a cycle, so give it its own outlet rather than a shared board.
