More info

  • AP201 exhibits a fair degree of resistance to chemical degradation (so that high throughputs of air and water vapour can be pumped without damage to the fluid) and it can withstand limited accidental admission of atmospheric air at operating temperature.
  • The fluid has low viscosity, which permits easy filling and draining.
  • It does not attack synthetic rubbers used for seals and gaskets in vacuum systems.
  • It is non-irritant, non-toxic and environmentally non-polluting.
