Air Dryer Testing

How to test your 3-line air dryer.

Great videos, please make more. Your Lucas gurling videos are very informative and helped me convince my boss to allow me to install the RC-01 check residual valve.

I have an issue where the governor is leaking out of the exhaust and the purge valve is leaking as well and won’t let it build up will try this to check the drier thanks !

Can I test this on a AD IS air dryer for a 2015 International Prostar with an ISX 15?

I’m very green, just had compressor replaced but it cycles like every 10-12 seconds??? My cousin says to replace the whole air dryer? Also the old head was bad and sent coolant into the air system….

Tried this test with a halidex dryer. When I connect the control line is purges but never stops. Tried this on the old dryer and on the new. It never closes back off.

Do these make really loud hissing noise for a few seconds during cold weather I've heard trucks pulling in the fuel Island and making a hissing noise like the dryer purging air for like 10 secs n then it goes away n does it again

I changed the entire air dryer. But still feels air coming out slowly through the purge valve non stop while im parked idling the truck. Is that normal? Changed every line and fitting that had even the smallest leaks. Now no air leaks. What else could be the problem?

My air dryer is not purging. Air pressure is goes past the max pressure which is 150psi . I bought a new air dryer a few months ago and gov. & the Same problem Is happening all over, any ideas what could be the problem?

[bishaap]

Where does the control line get air please help me?

[dieseldude]

So does the purge valve stay open until air needs to be built? If not how does it close

[tripn]

Mine "leaks" down to 105psi then builds pressure again. New compressor, new dryer and filter, new governor, New check valve. I'm not sure what I am missing. New compressor already blowing oil after a week because of it. Purges every 30 seconds or so. Builds to 120psi then the front axle tank goes down to 105psi.

I am lost. Any help is appreciated.

How can I do this on a AD-IS?
On mine the purge valve spits but then keeps exhausting air for about 10 seconds and the compressor reengages and the same cycle just continues endlessly.

I saw in another video where a guy found a leak at the supply check valve on a AD-9 but I don’t see that valve on the AD-IS.

Frustrated. Need help please.

Thanks & God bless

What if the control line is sending air back to governer

[itzdd]

Governor cut in and cut out is set for 95-120. What causes air dryer to cut in at 118 psi? It's cutting out at 120 psi. The air dryer is 1yr old.

Better to fix air pressure guage to avoid overfill.
