Specs and expected eta.
No more oil we used sealed needle bearings on the crank rod. There is now a high speed fan that blows over the cylinder head top down. The inverter is inside the case. But the most impressive thing Is the internal cooling system i designed. It blows outside air over the high pressure piston sleeve at the bottom of the case and threw the internal case up under the low pressure piston then threw a exhaust pipe exiting the case to atmosphere. I ran one for 14 hours strait with no effect on filling time after and also filled a scba tank from empty non stop also with no ill effect. I also put 100 hours of filling a high pressure 500cc vessel up over and over again and had no issues. I believe once and for all this unit will outperform any competitors pump in the same price range hands down! I will show it off in a few weeks at shot show but they are available from our JTS vendors now. We do suggest though to fill 500cc tanks in one run but anything larger to take 3 minute breaks every 15 min. to let the electronics cool down.

I can see using a hard Teflon coated piston but the rings need lube also.
I could see someone accidentally knocking that 12v to 120v switch and then POP. No thank you!
the Umarex ReadyAir is that the metal chassis isn't grounded.
