Automatically adjusts the vacuum level, optimising times and results.
Double seal
Improves vacuum retention over time and reduces the risk of leaks.
Vacuum preparation for GN trays
Direct vacuum sealing in Gastronorm trays for more convenient handling.
Professional vacuum machines, superior in every aspect
Designed with a focus on efficiency, ease of use, and compact size, this machine allows anyone to achieve professional results, with a lower usage frequency typical of domestic and semi-professional environments such as bars, small restaurants, catering services, and delis.
Temperature and sealing time adjustment
Temperature and sealing time are adjustable, allowing the packaging process to be adapted to different types of films and materials to achieve an airtight seal.
Maximum operational flexibility
Removable sealing bar
Removable sealing bar designed for tool-free removal and reinstallation, featuring a quick-release system with sealing width 2 x 2.5 mm, allowing fast maintenance and replacement operations. Specifically engineered to ensure operational continuity, ease of cleaning, and consistent, reliable sealing performance during packaging cycles.
Custom vacuum
Allows activation of a time-based vacuum cycle adjustable from 5 to 50 seconds, providing precise control according to product characteristics and processing requirements.
Marination function
Allows activation and adjustment of the marination function: with a single selection, the cycle duration can be set from 6 to 60 minutes, ensuring uniform and rapid marination of food products.
Smart Vac / Bag size
Allows selection of one of three sensor-controlled vacuum modes, automatically adapting the cycle according to bag size and ensuring precise and efficient packaging.

Jar vacuum function
Double sealing, achieved through two parallel sealing tracks, is specifically designed to ensure a stronger and more secure closure, improve long-term vacuum retention, and reduce leakage risk, even with irregular surfaces or liquid contents.
Bag positioning guides integrated into the chamber, designed to keep the pouch stable during the cycle. They facilitate alignment on the sealing bar, optimize sealing quality, and ensure consistent and repeatable results.
Easy access to the pump for oil filling or replacement, designed to enable quick and straightforward maintenance operations, reducing downtime and ensuring efficient and continuous machine performance over time.
Simplified maintenance
For a long service life
An innovative programme that activates 10 consecutive vacuum cycles to break down thick residues inside the pump and improve the oil’s flow.
This reduces energy consumption and extends the average service life of the oil, whilst ensuring the automatic cleaning of the vacuum pump.
High-tech, efficient, reliable
Our range of mobile hoods offers the very best in functionality and reliability. They feature a tilting stainless steel (AISI 304) body, standard welds that are wider than those typically found on the market (5 mm), a wireless welding bar, and a moulded, rounded basin to facilitate cleaning and maintenance.
Gastronorm trays and vacuum hose
Stainless steel
Durable and made entirely from stainless steel, these GN trays come with lids featuring airtight seals and a pressure-release valve, ensuring food stays fresh up to four times longer.
Available in capacities ranging from 5.8 to 28.4 litres, they are the ideal solution for chamber vacuum sealers. With the optional connection tube, you can achieve a 99% vacuum.

Frequently asked questions
Liquids can be vacuum packed in bags using a chamber machine. External suction machines are not suitable for vacuum sealing liquids in bags; however, dedicated Besser Vacuum containers can be used for liquid storage.
Reusing bags is not recommended due to possible residues or moisture, which may affect hygiene and vacuum quality. If the bag is perfectly clean, it may be reused.
It depends on the type of machine, bag size, and product volume. Chamber machines typically require between 20 and 40 seconds to vacuum pack food, although this may vary depending on pump power and size. External suction machines generally complete the cycle within 60 seconds.
For chamber machines, it is advisable to use the “gastro/pump” function to heat and clean the pump if the machine has not been used for several months.
