Component Specifications

Definition
A vacuum connection is a precision-engineered component designed to establish and maintain a reliable vacuum seal between a suction box and the vacuum source in industrial equipment. It ensures consistent negative pressure transfer for material handling, holding, or processing applications by preventing air ingress that would compromise system efficiency.
Working Principle
The vacuum connection operates by creating an airtight seal between mating surfaces, typically through mechanical compression (using clamps, flanges, or threaded fittings) or elastic deformation (using gaskets or O-rings). This seal isolates the suction box's internal volume from atmospheric pressure, allowing the vacuum pump to generate and maintain the required negative pressure differential for material suction or fixation.
Materials
Stainless steel (AISI 304/316 for corrosion resistance), aluminum alloys (for lightweight applications), engineered plastics (PTFE, PVC, or polycarbonate for chemical resistance), with nitrile rubber, silicone, or EPDM gaskets for sealing.
Technical Parameters
  • Leak Rate <1x10^-3 mbar·L/s
  • Port Size DN10 to DN100 (or 1/4" to 4" NPT equivalent)
  • Surface Finish Ra ≤ 3.2 μm for sealing surfaces
  • Connection Type Flange, quick-connect, threaded (NPT, BSP), hose barb
  • Pressure Rating -0.9 to -1.0 bar (vacuum), up to 10 bar positive pressure
  • Temperature Range -20°C to +150°C (depending on material)
Standards
ISO 5211, DIN 28400, ISO 16030, DIN 11864

Frequently Asked Questions

What is the most critical specification for a vacuum connection?

The leak rate is paramount, as even minor leaks can significantly reduce vacuum efficiency and increase energy consumption in suction systems.

How do I select the right material for a vacuum connection?

Consider the operating environment: stainless steel for corrosive or high-temperature applications, aluminum for general use, and engineered plastics for chemical exposure or where electrical insulation is needed.

Can vacuum connections handle both vacuum and positive pressure?

Yes, most industrial vacuum connections are rated for bidirectional pressure, but always verify the manufacturer's specifications for your specific pressure range requirements.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
