Apiezon AP201 is the leading brand of vapor booster diffusion pump fluid and should not be confused with lower quality '201' copies. AP201 is superior to other fluids because it delivers faster pump down-times, longer service life, easier maintenance and reduced top ups. It has been widely acknowledged that AP201 is the most reliable and cost effective product on the market.
In order to give the fast pump down-times required on industrial systems, diffusion pumps must achieve a high pumping speed. AP201 has been specially formulated to achieve these speeds. It also has a high critical backing pressure that allows the pump to be switched on sooner, thus minimizing pump down-time.
Apiezon AP201 also possesses properties that are matched specially to the vapor diffusion pump allowing it to achieve the optimum boiler temperature and maximise heater life.
Unlike other lower quality oils, AP201 is specially formulated to be highly resistant to oxidation. This prevents an increase in viscosity and build-up of tarry deposits on the diffusion pump vanes and jets. Consequently, the life of the oil is extended and the time needed to drain and clean the system during maintenance is reduced.
Further testimony to its exceptional quality is the fact that vapor diffusion booster pump manufacturers specify Apiezon AP201 and their warranties can be invalidated by the use of any other fluid. See MSDS and Data Sheet for specs and use below at AVAILABLE DOWNLOADS:
