Robinair 13119 Premium High Vacuum Pump Oil, Pint (12-Pack)

I used this oil in my Harvest right freeze dryer. It was shipped fast & price was amazing. It is one of the few oils that Harvest right recommends.

I use this oil In my freeze dryer pump. I’ve had absolutely no problems with it at all. Works well.

This is the best priced Name Brand Vacuum Pump oil we could find. Works well in chamber vacuum sealers.

The item is for 4 one gallon jugs and I've purchased it twice and received all four gallon jugs each time. I'm using it for a freeze drier with a high vacuum pump so it has to be good quality oil in order to process it in a reasonable time. It does do that and the oil lasts reasonably well for that. I really like that it's cost is so much less than buying one gallon or one quart at a time. It arrives very quickly and comes via FedEx for me. I have to replace about a quart of oil per week with how much I'm using it. The freeze drying gets small food particles and moisture vapor absorbed from the food into the vacuum pump oil. It gets about 5 freeze dry runs per oil change or about a full 7 days for me. I just drain about 2 tablespoons of oil after each run to remove any water drops that have formed and refill to the oil indicator fill level again and its ready for the next run. I'm very happy with its quality and cost as well as the quick shipping time.

A lot of different brands and price ranges for Vac pump oil out there. Though I have only tried a few I will say that this seems to be a perfect balance of price to quality. I use this in a Chamber style vacuum sealer and a harvest right freeze dryer pump. This oil runs much cleaner than black gold from my experience and I can get extra uses out of it after filtering. The black gold seems to get pretty filthy much quicker even with filtering between freeze drying sessions. So basically this oil is cheaper and runs cleaner.... whats not to like?
