I can't make up my mind whether these are acceptable interstage pressures or not (Bauer K14 compressor): 1st - 40 psi 2nd - 200 psi 3rd - 600 psi 4th - 3000 psi When I switch off the compressor, all gages hold their values well, but I have this nagging feeling that the first and second stages...

These folks sell excellent moisture separation equipment: Stainless Stell Breathing Air Purification Systems | Safe Air Systems Because they are stainless, they are maintenance free and worry free (no corrosion problems). They're even rated for outdoor exposure - very tough...

Hey, you guys were right on the money. I'm a little embarrassed in fact that I didn't discover how to do it on my own because it ended up being so simple. I disconnected the spring and the valve screwed right out... Thanks! :D

Does anyone know how to go about removing the knob from the condensate drain valve on a K14 block bauer compressor (#064008)? The manual mentions that there are two models, one with a retaining pin and another without. Mine appears to be the one without, but I am baffled about what else might...

The device that controls your moisture dump can be seen in pic #3. It is a simple timer that keeps the solenoid energized until a dump cycle, where it briefly cuts power to it. One knob controls the duration of the dump and the other controls the time between dumps. If you want to disable it...

Here are some of the things I have learned so far about compressors that I hadn't considered before entering the hobby: - Swagelok connections have been known to fail if not installed correctly (follow the manufacturer's install procedure for tightening exactly) - A common grease gun or (more...

I have to agree with iain, you are potentially taking a huge risk using a filter which has visible corrosion. Corrosion can be the beginning of stress fractures. Not sure about the UK, but in the US, visible internal corrosion can be cause for immediately condemning a cylinder. In fact, a...

Your line will impose a pressure drop at a particular flow rate. Start by picking a desired flow rate, line size, init pressure and line run length, then input this info into the following calculator: Compressed Air Pipe Lines - Online Pressure Drop Calculator If you see a pressure drop that...

Sounds like your final stage seals are shot and the hp air is leaking into your oil. Might be time to rebuild the final stage piston.

Not sure how old your K14 is, but like windyairman said, depending on the age, yours could be rated for 5000psi. My k14 for example (circa 1992) is set up for 3600 psi (nameplate pressure / relief valve settings), however the user's manual gives a maximum pressure of 5000psi. If you have...

I'm trying to replace a tube which has some vibration damage in my k14 Bauer compressor, and I'm beginning to educate myself about all the strange fittings and tube sizes. A tube which I had originally misidentified as 5/16" is supposedly 8mm tube with VOSS hydraulic compression fittings...

Fatigue Stress A large crack in metal starts much like a crack in your windshield. First you get a small star from a rock, and then on a cold day when you switch on your heater and stress on the glass is at its maximum, the teeny tiny crack can explode into one several inches long or more...

I have heard that an inlet restriction can cause a compressor to overheat. Is your inlet filter ok (maybe run it without the filter and recheck)? Could it be a problem with your inlet valve on the first stage?

each time you open a valve to fill the new tank, you would use the following equation to find the final pressure (Pf) in the tank to be filled: ((P1)(V1) + (P2)(V2))/(V1 + V2) = Pf Where P1 = Pressure in cascade bottle P2 = Initial pressure in your scuba bottle Pf = Final pressure of both...

http://www.bauergroup.com/pdf/produkte/ersatzteillisten/serviceunterlagen/behaeltertausch_e.pdf Just thought I'd share this link with you guys. I ran across this technical bulletin on Bauer's website which shows the dangers of using aluminum pressure vessels under repeated fatigue stress...

ok, so I got those stubborn piston rings in. Here's how I did it - the gap on the existing rings was pretty close to exactly zero. I don't know how the last owner managed to squeeze them in there, but they did. To gap the rings, I pushed an individual ring into the cylinder bore about half...

Hey, thanks for all of the tips, guys. I am still waiting for my replacement set of rings in the mail :D, but will post the results when they arrive. Sure is easy to burn up a bunch of $$ on broken ones. I'm also glad to see that I'm not the only one with ring issues.

I ordered some new piston rings for the third stage of my Bauer VT12 compressor, and presumed that slipping the cylinder over the rings would be a trivial task. Boy was I wrong. By wiggling and rotating the cylinder, I can nudge the first two rings into the cylinder bore, but the third ring...

ok, I just noticed that the link was a bit screwed up. Here's another try: http://www.jordair.ca/pdf/BAUER-WORKSHOP-MANUAL.pdf pg 90

ok, I managed to find it. Here's the link: Jordair Compressors Inc. - A Breath of Fresh Airpdf/BAUER-WORKSHOP-MANUAL.pdf Check out pg 90 for more details. Thanks for the offer - I would be interested in hearing about anything interesting you may discover.
