Product Description：
The CRVpro family includes all the features you'd expect in a direct drive rotary vane pump: gas ballast, forced oil lubrication, anti-suckback mechanism and thermal overload protection.
CRVpro vacuum pumps can be used for applications such as
freeze drying,
vacuum ovens,
schlenk lines,
backing turbo molecular pumps,
degassing,
vessel/chamber evacuation.
Direct drive pumps are not recommended for filtration, aspiration, drying electrophoresis gels, or other applications requiring sustained operation above 30 torr.
