Harvest Right XL Premier Vacuum Pump
This new Premier 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. Whereas, the oil in the Standard Vacuum Pump needs to be changed and filtered every 4 or 5 batches (when using the new 3/8 inch vacuum hose). You should only replace the oil in this pump with Robinair Premium High Vacuum Pump Oil (or with JB Industries Black Gold Vacuum Pump Oil). These may be purchased from Harvest Right, Amazon, and other locations. Do not use Dairyland vacuum pump oil in the Premier pump.
For use with Large and X-Large freeze dryers only*
- Lower Maintenance Costs
The Premier Pump does not need frequent oil changes and filtering, unlike other vacuum oil pumps in the market.
- Low Noise Operations
You can keep your Freeze Dryer running all night long as the Premier Pump is just as loud as your standard refrigerator.
Under cold and hot conditions the Premier Pump will pull a deeper vacuum than the Standard Pump. Under cold conditions the difference is .05 Pascal for the Premier Pump and .08 Pascal for the Standard Pump. Whereas, under warm conditions the difference is much greater: .05 Pascal for the Premier Pump and 2.05 Pascal for the Standard Pump.
Hence, the Premier Pump is especially not affected by warm, ambient conditions. When temperatures rise, it will pull a vacuum far better than the Standard Pump. The Premier Pump is just not affected by outside heat. It pulls the same deep vacuum even when it is in a warm environment.
Oil Mist Filter
Both pumps come with an oil mist filter. However, the Premier Pump’s oil mist filter allows for no oil spray at all and it will last much longer.
Electricity Use Use
The Premier Pump uses less electricity than the Standard Pump (187 watts versus 218 watts).
Under hot conditions at ultimate vacuum pressure the Standard Pump pulls 2.1 amps while the Premier Pump only pulls 1.7 amps. Hence, the Premier Pump is more efficient.
