Thanks very much. I appreciate all the information.
No problem glad to help. I've been building for Rix Europe the last 22 years so it gets easier LOL so they say.
I noticed that the SA-3 listed on e bay above sold, now that was a "tidy" clean pump fully as works current build spec and it sold for a fair price.
If your looking for something cheap, but with conditions.
RIX SA-3 Sweet Air Oil Free Breathing Compressor for SCUBA | eBay
Currently at $500 USD Again it is old 25 years and was used "upside down"
underslung under the base plate. (no problem with an oil free block) But its a fair price, however.
You just need the block, the Bauer P22 filter and the two small black water separators. Factor in a new base plate, motor, motor starter.
If they will split it down for you or shipping will be expensive the "space" it takes up
The cooling coil will have to be re plumbed but I'm guessing they still have the original coils and just added extra some extra tubing to the frame mounted separators.
Also factor in $800 to $1000 USD for complete SA-3 rebuild spares kit. It may not need it all but for the purpose of costing my experience say's factor it in. And consider a bearing or two. It's off a yacht by the look of it, wet damp salt water. Factor in a tin of "Plus Gas" WD40 and a big bag of new nuts and bolts and take care with any bolt seized into the main aluminium casing.
On the filling hose assembly it's missing a few parts
$50 for a on/off Sherwood line valve $39 for a check non return valve and $20 for a spares kit for that
BPR regulator, Also $60 for a new HP hose,
Another $500 for motor and starter $100 for baseplate, $40 for anti vibration mounts air intake filer and hose, $20 for drive pulley, $15 drive belt and bush and about 20 hours of your time maybe more.
Now thats about $2,300 US Dollars so far.
Kind of made that other SA-3 that went for $2,500 a pretty good deal. Iain Middlebrook
