I'm looking for options for a self-draining water-separator to install before a refrigerated air-dryer. Current CFM capability is ~55 CFM, but it might be higher in the future. I want something that will auto-drain, while in-use, meaning without having to depressurize. So I was told I want the water to be collected and then the float-actuated drain will expel it all completely on it's own. Seen options in Amazon already, so I've done basic research already, but not everything is on Amazon. I've seen stuff from Tsunami and some other brands, but I want to make sure I know what I want. I believe I want two components, one of which is the water separator, and the other is a float drain, but it looks like there are units that are both.https://www.compressorworld.com/50-c...1999-0131.htmlI tried calling them with no luck. Who has actual experience with such a beast?

Reply:No experience with commercial units, just the one I built myself. My theory was to not store any water in the tank, and it "should" reduce vapor in the air. So far it seems to be working. I have a drier 30 ft downstream from the compressor (5 HP 2 stage Ingersol/Rand) and I have yet to put any pellets in it. I also have filter/regulators at each drop with automatic drains, but I have yet to see them collect any water. The unit is just an old hydraulic cylinder with the piston rod removed and replaced with a sealed scrap bolt. The petcock was removed from the bottom of the air tank so it constantly gravity flows into the cylinder, which is held at an angle so the water drains to the outlet end. I turn the compressor on and off every day I'm using it (which is probably 4 days of the week) and hit the drain valve each time, so twice a day (up at a very handy level). The valve drains the water from the cylinder into a vented plastic jug due to air pressure. I close the tank when I turn it off, so it stays up to pressure while the lines are allowed to drain and activate the auto drains at the drops. I've probably posted this here before, so my apologies if it's old hat.

Reply:Always been curious. Why do you need to reduce pressure in the tank before you drain it???I just let 'er rip, and shut the valve when it runs clean. Am I missing something?
Reply:Auto drains are generally spring loaded (at least the ones on my regulator/filters are) so they only drain when pressure drops below 5 psi. When I drain my POS cylinder drain, I, as you say, just "let her rip..."Last edited by whtbaron; 7 Hours Ago at 08:35 PM.250 amp Miller DialArc AC/DC StickF-225 amp Forney AC Stick230 amp Sears AC StickLincoln 180C MIGVictor Medalist 350 O/ACut 50 PlasmaLes
Reply:I like the hyd hose BTW. No need to plumb with expensive, hard to work with, hard line. Mine's the same way for areas where there's a connection, or weird bend. 2500psi should be all you need for any compressor.

Reply:The rubber stall mat is a little over the top though (I'm just kidding.......I have the same). Does the vibration/noise interfere with your enjoyment of Vivaldi's Four Seasons?
Reply:I've dealt with 2 refrigerated air dryers at work and some big industrial units in the past. All of them had a built in auto drain. I can't see any reason to add another. On my compressor at home I have an ingersal rand electric auto drain. That one has a timer for how often it purges and length of time for purge.
Reply:I had some lines in really good shape that I had removed from equipment I wrecked for parts, so they got incorporated into the build when I plumbed the shop with black pipe. I also have fittings and a manual press so I can make my own. 1/2" for the outlets to the black pipe, and "I think" 5/16 to the cylinder drain. Not affected by oil when the compressor gets older, and yea, I've never blown one at 175 psi. It was another reason I chose the old cylinder for water storage. The only caveat is that you don't want it in a location that could freeze.250 amp Miller DialArc AC/DC StickF-225 amp Forney AC Stick230 amp Sears AC StickLincoln 180C MIGVictor Medalist 350 O/ACut 50 PlasmaLes

Reply:I can do dies for crimping cable, although I never get around to it. But hyd hose....................I'm gettin' a woody just thinkin' about it.

The problem with dies is that everyone tries to alter their fittings so only their dies will work ... no such thing as a "generic" hydraulic die system anymore. When I first picked this unit up, I could pick up cheap fittings at Princess Auto and everything worked great. They updated their line and I might have to do some creative grinding to make the old dies work again. I haven't tried it yet, so yes, they may be very hard to change.

Reply:I go kick the valve open once in w while when i read an auto drain thread. Got enough problems without adding some more fussy gadget to the system. Got them plumbed to a common tube thru the wall. You do not have to drain every 5 minutes.

Reply:My worst time is when we get into the 70* dewpoints during the peak of the Summer.
Reply:I wonder how it was done before the gadget? Not that tech isnt good but a simple valve every once in a while is super reliable. Some water sitting in the sump doesnt hurt.www.urkafarms.com

Reply:A plant that I worked at had something like a spitter vavle on the air compressor. It was mechanical and didn't give any problems. |
