compressor for airbearing table


Any suggestions on air compressor for Maplenoll ariadne table? I am new to this type of system and looking for advice from others who have ventured into air bearing equipment. I noticed Pluto uses Jun-Air compressors but have not found a US supplier. Other models or brands that are "quiet"?

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.
Hi all
A few years ago i used a vpi hw19 mk4 with an et2 tonearm
A dealer suggested to me to create a large 8 gallon plastic container with air being pumped in
I then had an airline out of the container that was driven by over pressurisation instead of the[wisa] pump itself thus removing the pulsing of the pump
I found this worked very well with my et2
I hope this may be useful
All the best

Oilmanmojo, you have it exactly backwards. The platter, although heavy, should take only about 4 PSI whereas the arm wants 40 or more optimally. If the platter takes more than this the bearing needs truing up. The WISA is not the best but in any case its low pressure is only suitable for driving the platter. It can be used effectively for this especially if you want to conserve on your arm pressure. Some people have used more than one pump for this reason.The platter is not as sensitive as the arm to pulses so you don't have to go to extra lengths to dampen them out. There are adjustments for diverting only as much as you need for the platter, leaving the rest for the arm. There are many other tweeks for optimizing this table. Do you have the signature version? Is the current pump not working?
Piedpiper--Thanks for the note. I will followup on the platter issue. I cleaned the bearing surface after I first hooked it up and it was not spinning easily without the platter on it. Once I cleaned it, it moved freely. I assumed the platter required more pressure due to weight of the platter. I am currently running with my shop vac (ran a line from it) but its a little too noisy because my media room is above my garage. I noticed as I reduced the pressure on my surge tank to approx 20 psig the sound started getting muddled and at approx 15 psig, skipping occurred indicating the arm was sticking. I did not have a strobe so I assumed the muddled sound was from a slower platter. In any case, I am looking for a compressor that can handle up to 40 psig since a tank pressure at approx 30 psig worked well.
My Ariadne is the reference and not the signature. The pump was not part of the sale so I am assuming the pump was broken or the person is keeping it. I have (and will use) a large surge bottle along with a couple of walker plenums between the table and the compressor. I saw your pics of your table and will be working to optimize mine in a similar fashion. I have just set up to see what the table can do as is. Any thoughts on further tweaks would be much appreciated
