Harvest Right Premium High Vacuum Pump Oil

Replacement Oil for Freeze Dryer Vacuum Pumps, 1 Quart

An oil vacuum pump depends on clean oil to seal and lubricate its internals, and that oil gathers moisture and contaminants over many freeze-drying cycles. Fresh oil helps the pump keep reaching the deep vacuum that freeze drying requires. Harvest Right Premium High Vacuum Pump Oil is recommended for use in Harvest Right oil pumps.

Each bottle holds 1 quart, enough to keep spare oil on hand for regular changes.

Frequently Asked Questions

How often should I change the pump oil?

Harvest Right recommends changing pump oil every 20 to 30 batches on its Home Pro freeze dryers and every 20 to 40 batches on the Countertop 360. Change it sooner if the oil turns cloudy, dark or milky. The change takes about two minutes.

Can I use other vacuum pump oil?

Harvest Right approves its own oil, Robinair Premium High Vacuum Pump Oil and JB Industries Black Gold Vacuum Pump Oil for its Premier pumps. Other oils aren't on that list and could affect performance. Stick with an approved oil.

Can I filter and reuse oil?

Yes. Harvest Right's oil filter lets you drain the pump, let water separate from the oil, and pour the clean oil back in. Replace the oil entirely if it stays dirty after filtering.

How do I know the oil level is right?

Check the sight glass on the pump; fill to the level Harvest Right marks for your pump. On the Countertop 360, fill to about the three-quarter mark. Don't overfill.
