The Weston stainless steel chamber vacuum sealer evenly removes air from the chamber around the bag in all directions (rather than from within the bag in one direction, as with an out-of-chamber sealer). Ideal for sealing soups sauces and marinades fish bone-in meats and works great for sous vide compression and infusion. The unit has rapid vacuum and seal time as it draws on vacuum strength. The fan-cooled motor prevents overheating for consistent sealing. The chamber sealer features an easy-to-read display for adjusting seal time and has an instant seal function. The lid is transparent for easy bag alignment. Includes thirty vacuum sealer bags of a variety of sizes.
