Dry Compressing Vacuum Pumps

RUVAC Roots Vacuum Pumps

Oil sealed vacuum pumps are used in all fields of vacuum technologies.

Rotary vacuum units are designed for pumping down air and nontoxic explosive and fire hazardous gases, which are non-aggressive to the pumped fluid and construction materials, vapors and gas-vapor mixtures which are precleared from condensed moisture and mechanical pollutions with oxygen content of air not more than 21 % . The maximum pumping speed is achieved in the inlet pressures range from 1,3·102 to 6,6 Pa (from 1 to 5·10-2 Torr). Also units can be used as pre-vacuum units for high vacuum pumps. Ambient class is UHL 4 according to all-Union State Standard 15150-69 for operation at the ambient and pumped medium temperatures from 283 to 308 K.
