I'm trying to understand both the functional difference, and life-expectancy of an oil-free pump vs an oil pump for a chamber vac.
Im looking for something durable, user friendly, and if an oil version is worth while, doing preventive maintenance on that pump at
home as sending these for servicing seem to be difficult to do.
I found this quote from a person at Amazon evaluating the VP210:
"" Researching the machine online, I read that this is dry rocker piston instead of the more expensive rotary oil motor. The dry rocker piston machine will tend to clog after sealing bags with alot of moisture in them (items like fish), but supposedly will still last 10 time longer than the typical countertop external strip sealing machine. The rotary oil motor machine will last 10 times longer than the dry rocker piston machine. However, I am using this on a home basis, not a commercial setting, so the representative said that the dry rocker piston would be fine. ""
your thoughts would be appreciated.
