Default My Franzinator

I built a franzinator out of 2" pipe. I couldn't successfully weld it together with a MIG. Close examination showed tiny cracks (cast iron pipe fittings). I brazed everything together. Does anyone see any issues with brazing?

The first picture shows all the parts...

This picture shows the center section with a 90 degree street elbow turn down...

This picture shows everything together...

Should I put this before or after the check valve?




Also, should I go make this same post on every forum I know of on the internet??? A lot of people do.

Default nice job.

I think that'll work fine, a properly done braze will easily handle the pressures that vessel will see. Just to pick a nit, the inlet street el is not centered in the body, this will give us an oppourtunity to see if it makes any difference in the design. I'm betting you won't be able to see or measure any difference, (outside body temp, side to side, or ammount of condensate produced) but if you have a way to check it, pass it on. RED

your check valve should be after your pump and before this seperator....typically the check valve is located inbetween the pump and the tank integral to the compressor. Are you wanting to put another one inline for some reason?

My check valve is currently mounted in a "stand alone" manifold between the compressor and tank. I could mount it either side of this seperator. I was wondering what would be best.

My street elbow in the middle section is not directly centered, but it is more centered than it appears in the picture. The angle of the photo exaggerates the offset. I considered trying to center it, but decided it was better to have a large contact area between the lip on the street elbow and the hole bored in the coupling for the braze to adhere to. I do not think it will make a big difference in performance.

Okay, I'm unclear here frankenfab: do you mean a check valve or a pop-off valve?

Check valve. If after the water seperator, the seperator will unload when the compressor shuts off. If before, the seperator will hold under pressure.

check valve after for two reasons first the compressor will start better with a larger unloaded volume second the check valve isolates the water in the separator fron the dry air so any evaporation stays out of the air.
if your system has room for it a cooler before the separator would realy improve the separation.

I wish I could draw on his cutaway, I would have the air come in the side just below the top to centerfuge and a nipple dropped down in the outlet about 6 inches. This would fling the air against the wall of the pipe and take the dry air from the center.

With the use of sqr tube, that air will be bouncing bad enough as it is. lol
