- 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.
