Hankinson refrigeration air drier

If you can use it on the air coming out from the compressor and you have a way to separate liquid water from the air flow, yes, it will be effective. If used at the intake only, no, it wont help much. 

You do realize that this Dryer is for a regular Aircompressor, if you put it on your Highpressure Outlet it blows 

I agree with george0815. You need to check the 'working pressure' on the drier. HPA is nothing to play with. 

I use this exact dryer system at work for compressed air actuated control system. I think it is about 175 psi max. This system works great for its intended purpose. If you put it on an regular air compressor it will supply dry instrument quality air. It would be great for a booster like a Shoebox or a Altaros. That thing new is about 1500.00 dollars and up according to CFM flow. It would work grea for a conventional air compressor but not for high pressure compressor. Hope this helps, Steve

If you could keep a low pressure tank (150psi) as a source for your 4500psi air compressor this drier could work. If the air being compressed only could come for a predried source. You will have moisture free compressed air. There is one potential problem if you filling an empty tank that has been open to the air in the room there will be some condensation when high pressure Air enters the tank. That’s why with refrigeration systems you pull a vacuum before adding gas.

I did an experiment a couple of months ago where I used my Yong Heng as a booster pump by feeding it dry compressed air to see how it affected pump times. Hooked the inlet to our hospital-quality compressed air system at work. It worked pretty well (pump time was almost cut in half), but I don't suggest feeding it more than 10 psia because the 2nd stage tube gets much hotter with more inlet pressure. So if you want to use your Hankinson, I agree with metamaniac that it would work well between a shop compressor and a booster like the altaros or a shoebox.

I work on commercial refrigeration systems, including refrigerated air dryers. As others already pointed out, this is not designed for high pressure air. However, if you have a standard shop compressor, you could feed the air from it into the air dryer, then run the output air from the dryer to a regulator that reduces the air pressure back to less than 10 psi (5 psi would be better) before plumbing it into the air intake of your HPA compressor. Hankison air dryers are top notch at what they are designed for, so good for you on getting your hands on one. Let us know how it works. Feel free to PM me if you have any questions about plumbing it in.

Airgnconvert,

I have been using a refrigerated air dryer in my “Charging Station” for about 3 years now. It has operated flawlessly in removing water from my system. It is piped in downstream of my oil less compressor. I have also installed a desiccant dryer on the outlet of the dryer to remove all traces of moisture before entering the Shoebox. Most refrigerated air dryers have a built in auto drain that allows for the automatic discharge of water that results from cooling of the air below its dew point. I have inspected my air tanks, airgun cylinders and my HP Diablo filter internals several times over the years and have found no signs of moisture or damage. I credit that to treating the air on the low pressure side with the refrigerated dryer and desiccant filter. I posted pictures of my system on here several years ago but I will repost one of them here.

You can do a search on line for your model and download a manual for it. There is also a manual purge on the valve.Next to the solenoid purge valve is a ball valve. If under pressure close the ballvalve and unscrew the knurelled screw to clean the strainer. Crud gathers in there. I don’t think the bypass is involved download manual read it completely and you will do fine.
