RH (Rotary Vane)
Oil-Lubricated Rotary Vane Vacuum Pumps
Safety & Efficiency
With the focus on operational safety and efficiency, Hokaido has constantly developed and optimized the rotary vane technology for over 15 years. Currently Hokaido RH rotary vane vacuum pumps are well reputed all over the world for their high-end quality and cost-effective vacuum generating throughout a wide range of industrial applications. Whether for intermittent or continuous use, you can rely on the RH.
These RH rotary vane vacuum pumps attribute their reliability and consistency to recognized Hokaido rotary vane technology with recirculation oil lubrication. It ensures a consistently high vacuum level which can meet the harshest operating conditions. And the vapor can be discharged without condensation with a gas-ballast valve opened.
Hokaido 2RH rotary vane vacuum pumps are featured by extremely high pumping speed, even in low-pressure ranges, leading up to a short evacuation time. The ultimate vacuum of 2*10-3 mbar is archieved by the two-stage compression with lubrication of circulating oil.
