Typical capacity

For this class of equipment, throughput can range from a few cycles per minute for single-chamber units to higher volumes for double-chamber or belt-fed systems.

Power supply

Commonly, these machines operate on a three-phase industrial power supply (e.g., 400V, 50Hz) for larger units, or single-phase (e.g., 230V, 50Hz) for smaller, lighter-duty models.

Vacuum pump type

Typically, rotary vane oil-sealed pumps are used for robust and consistent vacuum levels, though oil-free pumps are also available on some models.

Seal bar length

Units of this type commonly feature seal bars ranging from 300mm to 800mm, allowing for various bag sizes.

Chamber dimensions

Internal chamber sizes vary significantly; buyers should verify the specific dimensions to ensure suitability for their product.

Material construction

Most industrial vacuum packers are constructed from stainless steel for hygiene and durability, particularly in food processing environments.
