Multi-layer diaphragm compressors 420.1 MLG

The 420.1 MLG series of air-cooled sera diaphragm compressors are the perfect solution for small and very small gas flow rates. Their compact design and technical specifications have been proven in numerous applications in laboratories and a variety of industrial applications.

The benefits include:

  • Oil-free, dirt-free and leak-free compression of gases of all kinds
  • Secure multi-layer PTFE diaphragm technology
  • Continuous diaphragm monitoring with diaphragm rupture signaling
  • Continuously variable flow rates
  • ATEX compliant
  • Integrated control electronics (not appropriate for Ex areas)
  • Corrosion-resistant materials (stainless steels, plastics)
  • Suitable for continuous industrial operation
