How is the performance of VRD ?

 

1. Automatic anti-suck back valve, protect your system from oil and oil steam when power suddenly goes off.

 

2. Internal forced oil cycling system, fully lubricates the pump and make the lifetime longer and vacuum better.

 

3. Adjustable gas ballast for different needs of steam emission.

 

4. High reliable integrated cylinder structure, suits production lines better.

 

5. Different voltage types for different countries and regions.

 

6. CE Certificated.
