Stainless steel machines that allow you to pack products in an easy and convenient way. The attention to detail and high quality of materials ensure a perfect and durable vacuum. Each machine is equipped with a pump in an oil bath, equipped with a device that allows oil drainage and heating to use after periods of inactivity or cold weather. All models are equipped with a LCD display programmable in 5 languages (English, French, Italian, Spanish, German) which describes the process at any time of the vacuum for easy control of the cycle storage. The covers, equipped with a thick plexiglass, will provide a greater resistance to stress caused by frequent use. All the machines allow the vacuum outside the chamber in embossed envelopes for products of considerable length. Sap bells are especially useful for butcheries, restaurants, dairy farms, pasta factories and for all those activities that need to keep intact the quality of oxidizable materials.
