No need to disconnect your pump from the freeze dryer or the flush kit, and no messy oil spraying everywhere. With the flush kit, you can filter the contaminants out of the pumps oil after each use of the pump, keeping the oil in the vacuum pump clean. It is easy to install, and makes maintaining your Harvest Right freeze dryer vacuum pump and oil a breeze, which means you spend less time changing oil and more time freeze drying the recipes you love!
