Omega Air Charger

Considering buying an Omega Air Charger. I know it is a slow filler. The question I have is: If it is lubricated by a grease cup system (which I like) for the piston(s), how does lube get to the rod bearing/ crankshaft bearings? Is it oil lubed for the bottom end? Can someone who has one of these answer that? I would appreciate it. Seems like a good unit and pumps faster than my F10 Shoebox.



Thanks,

 I've had mine for over 2 years and use mine just for filling my rifles. So far it has performed flawlessly. The manual says only this about lubrication:

Only the highest quality Bio-based food grade lubricants from Renewable Lubricants are used in the crankshaft and multi-stagehigh pressure piston chambers. This protects the PCP air tank's inner surface from oxidation while having excellent adhesion/cohesion properties. Independent control of the compressor motor allows the radiator to continue to function while the motoris not running ensuring and optimizing chamber cool down when extended filling is required.
 
Grease cup ONLY delivers lubricant to the roof of the 1st stage keeping the BIGGEST piston and rings lubricated within the Aluminum housing.

From there I'm sure some residual lube starts passing threw the other two stages keeping things slippery.

Every time I blow off the moisture can't say I've ever sen grease come out, tho the water is clouded as if containing some trace oil.

Almost 4 years now on my Alpha 90 knocking on @180 hours run time. Serviced once at 88 hours.
 
I have an Omega - have had two issues. Both didn't turn out to be a big deal only because their national service guy, Todd Brown, is one of the most customer service oriented guys I have ever met. It is running great with about 60 hours on it at this point. If you don't let your bottles drop off more than about 25% to 30% and keep them topped off, it doesn't take more than 30 to 45 minutes of run time to keep them up.

I am satisfied with mine and wouldn't be without it.
