Description
The SMC-HTE-28 and 40 are single-stage rotary vane vacuum pumps with oil recirculation, designed for compact and efficient vacuum generation. The rotor is directly keyed onto the motor shaft, reducing mechanical complexity and enhancing reliability.
Each pump features an oil mist separation system for cleaner exhaust and lower oil consumption. A gas ballast is integrated to prevent condensation when handling small amounts of steam, making these pumps ideal for light industrial and laboratory applications where consistent, low-maintenance vacuum is required.
