Thanks for the info Crem1
I wonder if the DR-500 has an air conditioner, or Filter with a oil/water separator.
What is the discerning factor that one has the "Super Quiet" pump (SQP). Other then then the obvious, of it being quieter, what are the visual cues that one has a super quiet pump? I believe that the SQP was an option.
What are individuals using as the replacment for the lubrication of the top air bearing? ( the grease substance that originally came in a syringe) As well as the replacement for the viscous oil in the trough?
What about replacment belts?
