**Product Introduction:**
This series of vacuum pumps are essential equipment used for removing air from sealed vessels. They can be used independently or as a forepump, process pump, titanium pump, booster pump, roots vacuum pump, gas circulation cooling roots pump, oil diffusion pump, or molecular pump. These pumps are widely applied in industries such as vacuum coating, vacuum heat treatment, vacuum smelting, vacuum tubes, bulbs, refrigeration, chemicals, packaging, forming, medical devices, laboratories, vacuum drying machines, and vacuum filtration.
**Key Features:**
- Operates continuously within a temperature range of 5 to 40°C and with an inlet pressure below 1330 Pa.
- Equipped with a gas ballast valve to handle small amounts of water vapor, extending the oil life except for the 2X-4A model.
- Specifically designed for neon light manufacturing.
- Features multiple suction holes to reduce energy consumption.

**Notes:**
- Use a mercury vacuum gauge at the pump’s inlet port for testing.
- For accurate readings, use a thermocouple gauge, resistance gauge, or another total pressure-type gauge.
- The inlet and outlet ports have a G3/8" diameter.
- Cooling speed varies depending on the model, with some models having specific values listed in the table above.
