How often should the oil in a dual-stage vacuum pump be changed?

Changing the oil in a dual-stage vacuum pump is essential for maintaining its efficiency and longevity. The correct frequency for oil changes is every 10 hours of operation. This is because as the vacuum pump operates, the oil becomes contaminated with moisture, debris, and other impurities that can affect its performance.

Regularly changing the oil helps to ensure that the pump maintains its vacuum integrity and prevents damage caused by these contaminants. Additionally, fresh oil provides better lubrication, which is vital for the moving parts of the pump to function correctly.

Maintaining this schedule is aligned with industry best practices, as it allows the pump to effectively remove air and moisture from refrigeration systems, ultimately ensuring optimal performance.
