The new Pascal 2021 HW from Pfeiffer Vacuum, Nashua, N.H., boasts a 2-stage rotary vane pump with what is said to be the highest vapor capacity on the market.
Optimally suited for all applications where water vapor is expected, such as low temperature sterilization and drying, the optimized design and gas ballast system allows the pumping of large volumes of vapor without condensation inside the pump. This prevents accumulation of fluid that would adversely affect the service life of pump and the pump oil.
