This commercial chamber vacuum sealer is built for kitchens that seal food all day. A 900W heater and dual seal bars work with a 15.7 inch seal length and 10mm wide seam to pack large steaks, whole bread loaves, or bulk goods without leaks, while twin motors share the load so back-to-back batches will not overheat. The -100kPa vacuum removes nearly all the air, keeping meat, seafood, and dry goods fresh far longer in the freezer or pantry. It rolls on industrial casters to move between stations in busy kitchens, bakeries, or butcher shops, and the stainless steel 201 body with an acrylic lid resists corrosion from oily or salty foods. At 143.3 pounds it is meant for permanent placement, and because it draws 3500W it ships with an air switch instead of a plug, wired to power following the included labels.
