Air Dryer

[Welderpaul]

Air dryer jobbie.

When connected to the air line, air escapes from the bottom (Drain off?)
Everything seems tight, but it looks like there is a hole right through the centre?

Anyone know?

I had trouble with one the other day, kept fiddling and it sealed eventually.... strange one, it looked like there was a bit missing.

Back of a plasma?

 

[Welderpaul]

Yeah, looks like theres something missing out of this one.
Plasma, aye. Theres one on the compressor and the air line is not that long, so no issue, but ideally have it on the back of the machine.

That looks like a push-fit connector (the pic's a bit fuzzy) could it have been connected to a remote drain tap?

 

[Welderpaul]

Yes, it looks like a push fit connector. Hang on.

 

[Welderpaul]

Camera has focussed on the wrong thing, but deffo something should be in there. You can see the small spring clips that would hold a pipe(?) in place.
Surely air shouldnt come out of there?

 

[rtbcomp]

Does the red ring move in and out slightly?

This is what I mean by push-fit http://www.beal.org.uk/hoses-tubing-fittings/push-fit-equal-connectors/nylon-push-fit-coupling-4mm-10-/prod_1094.html - as I'm sure you know, you stuff a piece of pipe up it and it's held in place by barbs, which are retracted by moving the ring when you want to release the pipe.

Looks like a pneumatic push connector to me, possibly an automatic-stop one where the mechanism is leaking slighly? Does the whole thing screw off to reveal a BSP standard fitting?

 

[Welderpaul]

Exactly that RTB.

 

[andyxxxx]

Maybe a BSP fitting ball valve as a replacement? I'm not keen on the plastic push fittings.

 

[Wozzaaah]

We have similar to that at work and they exhaust when you push the fitting to one side then seal when you let go, the fitting is there to allow you to fit a drain tube.
Has it been ok and just started leaking or is it on a machine you've just bought?

 

[Welderpaul]

It looks like the black bit on the end turns through 90 degrees. Theres a '0' and a '1' with an arrow between which i presume is open/dump out water and closed.
More fiddling required.
Never seen filters with a drain tube out of the bottom.

its a push fit to allow the use of a auto drain valve. we have a few at work like that with a solenoid valve that opens for a burst occasional to check there is no water in the tank. the bit with the white nob on looks like a normal operative required drain off

The one I have self drains when you drop the pressure off, As soon as you pressure it back up the air pressure pushes down and reseals the spring loaded auto valve,

My plasma has one that does exactly the same - drains when you depressurise it. Has a pipe attached to the bottom which leads out of the machine.

Spot of dirt in yours Paul so it won't seal?

 

[Welderpaul]

I need to take it apart and clean it/try it back on. Dirt could well be the trouble.
Looking at the price of new consumables i need the air to be as dry as poss, so a second filter won't go amiss.

 

[madkayaker]

have a look at getting an air dryer. at work we have a couple of different sorts one is an inter cooler between pump and tank the other is between the comp and a dry air tank.

Bought one of these last week

[Welderpaul]

Looks like it would pay for itself in savings in consumables over a relatively short period.

Just looked at the purge drier Drains, 0.1 of a micron takes some believing, thats a 250th of a thou!!! I have one drier inside the plasma and another fitted at the inlet.
