Snorkel Vacuum Sealers (aka External Vacuum Sealers) remove air and moisture to protect your food or other products from spoilage. Food flavor and freshness are greatly extended, and snorkel/external vacuum sealers also protect machine parts and electronic components of all kinds from environmental hazards. Because external snorkel-type vac sealers aren't restricted by chamber size, they can seal objects and materials of pretty much any size and shape. Click the products below for details!

How external vacuum sealers work
Most commercial vacuum sealers are chamber-style machines. They’re great for sealing anything that will fit inside their enclosures. But to seal larger items, you need an external vac sealer. With this type of machine the item to be sealed is placed in a sealing bag, and the open mouth of the bag is placed between the machine's sealing bars. Air is rapidly extracted through a snorkel tube extending between the bars, then the tube automatically withdraws and the bag’s mouth is heat sealed.
真空sealing a wide range of products
With seal bars up to 50 inches wide, very large items can be sealed. More of our vacuum sealer customers use their machines to package food, but external vacuum sealers are often used for a variety of other products, from electronic assemblies and machine parts to reels of movie film or magnetic storage tape and sterile medical instruments.
Heavy duty vacuum pouch options
Plastic vac sealer pouches are available for our external vacuum sealers ranging from lightweight up to military grade. Vacuum sealing pouches have a special laminated construction with a poly inner layer that allows them to be fused by heat sealing, and an outer layer of nylon that’s highly impermeable to air migration, even under great pressure differentials. The barrier created by properly sealed, quality bags lasts for years.
External vacuum sealer models
US-made AmeriVac external vacuum sealers like theAmeriVacs AVN-20provide a great solution when object size requires seal bar openings as wide as 50 inches. They offer many available options including stainless cabinet, dual (upper & lower) seal bar heating for military grade bags, gas flush, dual extraction nozzles, additional vac or gas cycle, low-pressure bar closure, digital temperature control, and ported exhaust for clean-room compatibility. AmeriVacs units are in use across the U.S. and internationally in settings including food service, electronics, data storage, film preservation, hospitals, and aerospace.
TheDajiang/DMC 700 external vacuum sealeroffers a stainless steel conveyor configuration that lets you position even heavy packaging easily.
