High-vacuum pumps

High-vacuum pumps are used when the required ultimate absolute pressure is very low.
High-vacuum pumps can be constructed from a single rotor-stator assembly (single stage) or from two rotor-stator assemblies connected in series (double stage).
Ordering Examples:

TEC.RC2D HIGH-VACUUM PUMP 0.01 mBar, 2 m³/h, DOUBLE-STAGE
TEC.RC4M HIGH-VACUUM PUMP 0.1 mBar, 4 m³/h, SINGLE-STAGE
TEC.RC4D HIGH-VACUUM PUMP 0.01 mBar, 4 m³/h, DOUBLE-STAGE
TEC.RC8M HIGH-VACUUM PUMP 0.01 mBar, 8 m³/h, SINGLE-STAGE
TEC.RC8D HIGH-VACUUM PUMP 0.01 mBar, 8 m³/h, DOUBLE-STAGE
