HIGH VACUUM PUMP (without pressure added)
The vacuum pumps are designed for use on A/C-R system, refrigeration system
- TW-1A: 1/4HP, 2.5CFM, 1-stage
- TW-2A: 1/3HP, 4.8CFM, 1-stage
- TW-3A: 1/2HP, 6.0CFM, 1-stage
- 2TW-2C: 1/2HP, 5.0CFM, 25Microns, 2-stage
- Built-in high accuracy vacuum gauge to monitor evacuation progress, reading the gauge shows there is either high contamination or a large leak in the system.
- Gas ballast valve to reduce water vapor in the oil compartment
- Forcing oil inject device, to keep the pump operating at peak efficiency.
