There are several advantages to using Fomblin® Y HVAC fluids in diffusion pumps:
Will not polymerize when exposed to oxygen, ionizing radiation or accelerated subatomic particles. The system stays free of varnish and deposits from fluid decomposition.      

Non-flammable:

  • Resistant to oxidation of explosion and hot fluid can be exposed repeatedly to air without harm to the fluid while running the pumps 
  • Inert to most reactive chemicals, the fluid can be used in direct contact with materials such as UF6, F2, PCI3, BF3, without harm to the fluid 

Fomblin® Y HVAC fluids have been specially developed in order to combine narrow molecular weight range and controlled viscosity with an extremely low vapor pressure. Thus, they provide superior performance in high vacuum applications, especially systems exposed to aggressive
