The Oil-Free and Maintenance-Free Vacuum Pump for Harvest Right Freeze Dryers was released in 2017.It's faster and quieter than the two oil-based pumps — the JB Industries 6CFM Pump, and the Harvest Right Branded 7.2CFM Pump). EpicenterBryan has affectionately named this new dry pump "The Eagle."

**UPDATE** We no longer recommend Harvest Right Oil-Free Scroll Pumps due to recent quality issues. We do highly recommend the Harvest Right Premier Pump — we have heard of no issues with the Premier Pumps from any of our customers! For more information and pricing on the PREMIER PUMPS, please contact Harvest Right directly. **ANNOUNCEMENT** EpicenterBryan is now using a LEYBOLD VACUUM PUMP to operate our two freeze dryers. For more information and pricing on the Leybold Pump, please Contact Us. |
In this video, we discuss:
- The price.
- The noise level and frequency content of the sound of the new oilless pump.
- How long it takes to process a batch of food with the new oilless pump and compare data with the new 7.2CFM Harvest Right pump (shipped with all Harvest Right freeze dryers starting in late November 2017), as well as the older 6CFM pump from JB Industries.
The Harvest Right oil-free dry pump is expensive but, like all scroll-type pumps, the machine work must be very precise to operate at such extreme vacuum levels. To learn more about how a scroll type pump works, there is an excellent video here: Working Principles of a Scroll Compressor.
In summary, EpicenterBryan has been using the new Oil-Free Pump for several months, running it fairly consistently. It is far quieter than the standard oil pump(s) and, because it's maintenance free, there's less fuss with the oil changes and more freeze drying going on!
