Description
The DZQ-700/850/900/1000 2SA series covers large-format industrial double chamber vacuum packers with 700 to 1000 mm sealing-width configurations. These models are considered for wide bags, heavy packages and production-line projects where chamber format, pack handling and outfeed flow must be planned together.

Gas Flushing
Supports filling with protective gases such as nitrogen and carbon dioxide to replace oxygen inside the package, reducing oxidation and extending freshness. Suitable for meat, food, coffee, and other products.

Program Memory
Equipped with 6 memory buttons for quick access to customized settings, improving operation efficiency and ensuring consistent packaging results.

Custom Vacuum Chamber
The chamber size and height can be customized according to product requirements, providing more packaging space for oversized and special-shaped products.

Soft Air
Uses controlled air release to ensure smooth pressure recovery, protecting fragile, sharp, and sensitive products while improving vacuum packaging quality.

Pump Self-Cleaning Function
The automatic cleaning program removes moisture and impurities from the pump, reduces oil emulsification, maintains stable pump performance, and lowers maintenance requirements, especially suitable for high-humidity food packaging environments.

Cutting & Sealing
Adopts heat cutting technology to achieve precise cutting and reliable sealing, creating cleaner edges, better appearance, and more professional packaging results.

Pump Dust Filtration
Equipped with a dust filtration system to prevent powder particles from entering the vacuum pump, improving operating reliability and extending pump service life.

Insert Plate
Reduces the effective chamber space to speed up vacuuming while helping position products accurately for more stable sealing performance.
High-Quality Vacuum Pump
Equipped with a rigorously tested high-quality vacuum pump and supported by quality inspection reports, the machine ensures stable and reliable vacuum performance. Compared with ordinary low-cost pumps, our vacuum pump features a stronger structure, lower operating noise, longer service life, better continuous operation capability, and reduced performance degradation risk.
Multiple vacuum pump brands and configurations are available according to customer requirements, including international brands such as Busch for high-capacity pumps above 100 m³/h, providing flexible solutions for different applications.


Effort-Saving Design
Through optimized mechanical structure and balanced support system, the machine significantly reduces the effort required for lid operation. It helps lower operator fatigue, improves workflow efficiency, and supports stable long-hour continuous production.
Rational Internal Layout Design
Featuring a well-organized side-mounted electrical system and dedicated maintenance access door, the machine allows quick and convenient inspection of internal components. The optimized layout simplifies maintenance procedures, improves service efficiency, and enhances long-term equipment reliability.

Heavy-Duty Capacity for Large-Format Packaging
The DZQ-700/850/900/1000 2SA is a heavy duty vacuum sealer built around genuinely large chambers: 210 mm chamber height and seal bars from 700 to 1000 mm take whole-muscle meat, large cheese wheels, and oversized retail packs. For buyers comparing a large commercial vacuum sealer or a large chamber vacuum sealer for bulky products, the range offers four frame sizes with 100–300 m³/h pumps — and the 1000 mm model is among the largest vacuum sealer chambers available on a double-chamber line.
As a heavy duty commercial vacuum sealer rated for 12 hours of continuous running, it is available with a flat chamber for standard bags or a deep chamber for high-profile items — a double chamber vacuum packer with deep chamber option that few machines in this class offer. The mechanical lid-assist design needs no compressed air, and the optional insert plate adapts the chamber floor for smaller batches, making the series a flexible heavy-duty vacuum packer for high-output lines and large format packaging across meat, seafood, and industrial goods.
For powder handling and high-automation packaging, see DZQ-850 2SE with its automatic lid, PLC and touch-screen control — the high-spec partner to the 2SA heavy-duty range.
