Harvest Right Oil Filter

Clean and Reuse Vacuum Pump Oil Between Changes, Filter System

Over many freeze-drying cycles, vacuum pump oil collects water and contaminants that reduce pump performance. Replacing it every time costs money and creates waste. The Harvest Right Oil Filter lets you drain the pump into the filter, separate the water, and pour clean oil back in.

Harvest Right includes one oil filter with each freeze dryer shipment, except orders with the oil-free pump upgrade. This is the same filter, sold as a replacement or spare.

Key Features & Benefits

Frequently Asked Questions

How do I filter the pump oil?

Drain the oil from the vacuum pump into the filter and let it pass through the cartridge. Water settles to the bottom while clean oil sits on top. Pour the clean oil back into the pump, leaving the water behind.

Why filter oil instead of replacing it?

Filtering removes water and contaminants so the same oil can be reused, which cuts oil costs and waste. Harvest Right says filtering preserves pump life and improves freeze dryer performance. Replace the oil if it stays cloudy or dark after filtering.

Can I filter other oils with it?

No. Harvest Right states the filter should be used only for vacuum pump oil. Use it with Harvest Right-approved pump oils.

When should I replace the cartridge?

Replace the cartridge when oil drains slowly through it or comes out still milky or dirty. Harvest Right sells replacement cartridges in 3-packs. Keep a spare so filtering is never delayed.
