DMC 450A Commercial Vacuum Sealer

The DMC 450A commercial chamber vacuum sealer offers automatic operation. Just place your bag in the chamber, close the lid, and the machine cycles automatically to provide fast vacuum sealing.

When the sealing cycle is complete, the vacuum releases and the lid lifts automatically, ready for your next package. Vacuum strength and heat impulse duration are separately adjustable. When vacuum sealing packages that don't completely fill the chamber, cycle time can be cut dramatically by placing poly spacing boards in the vacuuming chamber to reduce the amount of extractable air.

Choice of 1-bar or 2-bar model: The standard 450A model has a single seal bar, 17.4" long, positioned at the front edge of the vacuum chamber. The 450A-2BG has two seal bars, each 16.75" long, positioned at the left and right sides of the chamber. With either unit, you can use the full seal bar length for large bags, or seal several narrower bags at once by placing them side by side.

    – Sean Gerych, WV

Gas flush option: The 450A-2BG is equipped for gas-flush operation. This allows you to replace the air in your package with an inert gas from your regulator-equipped gas bottle, so the finished package is oxygen free, yet its contents are not "sucked down" by outside pressure. The 450A-2BG will also operate in normal mode, without using the gas-flush feature.

DMC 450A sealers have a 20 cubic meter/hour vacuum pump. Outside dimensions are 23"D x 21.2"W x 19.25"H (with lid closed). The housing is stainless steel housings and the full-view dome lid is made of heavy duty unbreakable polycarbonate.

  • Good machine
    By on - Verified Buyer
    We process four beef and about a dozen hogs each year, and we run the DMC sealer up to eight hours a day. It works perfect, like a butcher shop operation, just vac pack over and over again with no cool-down needed. Maintenance is quick and easy. Good machine, good value.

  • So much better
    By on - Verified Buyer
    We processed two whole hogs in record time. The DMC chamber vac is so much better than the single pouch sealers that we've been using, and Pleasant Hill Grain took care of us beyond expectations.

  • Good restaurant vac sealer
    By on - Verified Buyer
    Our new DMC vacuum sealer is simple to use, so training employees is a snap. Its chamber size handles all or our restaurant's vacuum packaging needs, and it's easy to clean. I'd recommend this vac machine to anyone.

    Even though the sealer we purchased was backordered, your staff stayed in contact with updates on delivery dates and we received it just in time for a large butchering project. Will definitely order from you again!
