Premier Vacuum Pump by Harvest Right Industrial Grade Design for Your Harvest Right Freeze DryerBetter than Standard Pump Technical Specifications: Oil: Robinair Premium High Vacuum Pump Oil or JB Industries Black Gold Vacuum Pump Oil Only DC Motor Voltage: Standard, 115v, 60Hz Dimensions: 16.3″ x 6″ x 12.1″ Weight: 32lbs Noise: 52 decibels DETAILS: Product ComparisonPremier Oil Pump vs Standard Oil PumpOil ChangesThis 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.Vacuum PressureUnder 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. NoiseThe Premier Pump is substantially quieter than the Standard Pump, 52 decibels versus 64 decibels. The Industrial Pump at 52 decibels is about the same as a refrigerator.Oil Mist FilterBoth 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.Power UseThe Premier Pump uses less power than the Standard Pump (187 watts versus 218 watts).AmperageUnder 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.WeightThe Premier Pump is easier to move around as it weighs 5 pounds less than the Standard Pump (32 lbs. versus 37 lbs.)LifeThe Premier Pump is more durable and will last longer than the Standard Pump.
