AP201 vapour booster pump fluid

Apiezon® AP201 is a hydrocarbon fluid prepared by molecular distillation and protected against oxidation by a thermally stable additive of matched vapour pressure. It has an auto ignition temperature of 305°C.

Features and Benefits

  • 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.

Applications

  • Furnaces
  • Vapour Booster
