Robinair 13204 Premium High Vacuum Pump Oil - 4- one gallon jugs

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.

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

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

Received 4 gallons as advertised and at the best price i could find anywhere on the internet.

I used this oil on my dairy farm in the vacuum pump for the milking machines. Worked good so far. Price was fair.
