How to use Wevac CV12 Turbo?

Hi Mark McCann, Technical Advantages: 1. Oil Vacuum Sealers offer higher vacuum strength, better heat dissipation, and potentially longer life, but require regular maintenance. 2. Dry Pump Vacuum Sealers are easier to maintain, cleaner, and less prone to downtime, but may not achieve the same vacuum strength or longevity as oil-sealed models. Warranty Differences: 1. Oil Vacuum Sealer: The warranty includes stipulations about regular maintenance, such as oil changes, to remain valid. Failure to perform these maintenance tasks could void the warranty. 2. Dry Pump Vacuum Sealer: The warranty is often simpler, focusing on the general operation of the machine without specific maintenance requirements like oil changes. All Wevac Vacuum Sealers, whether oil pump or dry pump, come with a 2-year warranty. Claire Marketing claire@wevactech.com

I wonder what technical advantage there is for the oil versus the dry pump? Also is there a difference In warranty? Thank you, Mark McCann
