The model to look at is the Dophin Five Star.

Good luck.

I have not seen any of the aquarium pumps that deliver pressure above 10 psig. The lower pressure will work for the arm but the maplenoll has a 50# platter resting on the top part of the air bearing. I find when my supply pressure falls below 20 psig, the system starts struggling. I do love the quietness however with the design of the aquarium pumps and am looking for a similar "quiet" pump that can deliver approx 30-40 psig. Anyone ever use airbrush compressor?

I do believe the "WISA" aquarium pump is considered the best,in this application.Not cheap,and it had a distributor who modded it,for audio purposes.I wish I could give you more input here.Also,some compressors used for dentist drills(don't laugh)have been used with superb,high pressure results,on arms like the Air Tangent.I had two friends who did this,and once one got past the humor,it was a sonic revelation.
I'd still go with a nice new WISA,which should be available commercially.
good luck!

Give 'ol Bruce Thigpen at Eminent Technology in Tallahassee, Florida, an email or a call and see what he recommends these days. Bruce has been the air bearing guy literally from day one, and was closely involved with the development of the Maplenoll air bearing. Besides, he's one heck of a nice guy and is always very helpful. Bruce will get you the correct answer.
