Astra Vacuum packing machine

Astra – Semi-Professional Chamber Vacuum Sealer

Astra sits in Besser Vacuum's Semi-Professional range, positioned between the domestic external suction machines and the full Fusion/Expert chamber lines. It's a compact chamber sealer — meaning it can vacuum-seal liquids directly in bags, unlike external suction models — designed to deliver professional results at a lower usage frequency, suited to homes as well as bars, small restaurants, catering services, and delis.

Key highlights

• LCD display – immediate, precise control over every function, with simple, intuitive operation.
• Timed vacuum cycle – vacuum and sealing times can be quickly adjusted, optimising both processing time and results; the custom vacuum cycle is adjustable from 5 to 50 seconds for precise control based on the product being packaged.
• Smart Vac – automatically adjusts the vacuum level based on bag size, via one of three sensor-controlled modes, optimising both time and results without manual guesswork.
• Double seal (included) – two parallel sealing tracks improve long-term vacuum retention and reduce the risk of leaks, even with irregular surfaces or liquid contents.
• Vacuum preparation for GN trays – direct vacuum-sealing in Gastronorm trays for more convenient handling.
• Marinating function (included) – a single selection lets you set a marination cycle from 6 to 60 minutes, ensuring uniform, rapid marination.
• Jar vacuum function (included) – extends preservation to rigid containers as well as bags.
• Adjustable temperature and sealing time – lets the packaging process adapt to different films and materials for a consistently airtight seal.
• Removable sealing bar – a tool-free, quick-release design (2 x 2.5 mm sealing width) allows fast maintenance and replacement, keeping operations continuous and cleaning straightforward.

Design and durability

Astra features a tilting AISI 304 stainless steel body, welds wider than typical market standards (5 mm), a wireless welding bar, and a moulded, rounded basin for easy cleaning and maintenance. A dedicated maintenance programme runs 10 consecutive vacuum cycles to break down residues inside the pump and improve oil flow, reducing energy consumption and extending the pump's service life.

Compatible accessories

• Gastronorm trays and vacuum hose – three models (100, 150 or 200 litres), fully stainless steel, with airtight-gasket lids and a pressure-release valve that keep food fresh up to four times longer; capacities from 5.8 to 28.4 litres, reaching 99% vacuum with the optional connecting tube.

What it's for

Astra brings chamber-machine capability — including liquid sealing, marination, and jar vacuum — into a compact format suited to lower-frequency professional use: ideal for small businesses that need more versatility than an external suction machine offers, but don't require the volume or programmability of a full Fusion or Expert Line model.
