Premier Vacuum Pump

The Harvest Right Premier Pump works great with most Harvest Right freeze dryers. This pump rarely needs to have the oil changed or filtered. The pump has a gas ballast feature that makes it so water does not stay in the oil.

Because of this, the oil in the pump will be pristine and clear, even after 30 or more batches. You simply won't need to change the oil until you have run 20 or more batches. You should only replace the oil in this pump with Harvest Right Vacuum Pump oil, or Robinair Premium High Vacuum Pump Oil, or with JB Industries Black Gold Vacuum Pump Oil.
