ChamberKleen™ Diffusers

Gas diffusers are ideally suited for vent applications on load lock interfaces or other vacuum chambers where large volumes of gas are flowing in a short amount of time. The Pall ChamberKleen™ 1100 and 5500 Series diffusers combine a stainless steel filter and a unique diffuser membrane that allows flow in 360 degrees. This combination allows large volumes of gas to flow in a uniform manner, limiting the disturbance of particles in the chamber. Consequently, fast vent times can be achieved with little particle disturbance.
  • Reduces turbulent gas flow during venting of process chambers
  • 360° diffuser design optimizes gas flow
  • 316L stainless steel filter medium
  • 316L stainless steel diffuser
  • Cleanroom manufactured and packaged
