Diablo Moisture Filters

Humdinger, I agree on the freedom compressor...I have the f10, and love it..I have about 7 hours on it, and i’ve Filled 5 times from 3600to 4600..after filling, the pressure cools to about 4450...I have a decent silica dryer on the intake to the f10, and so far nothing on the output to my tank...I’ve changed to silica twice, mainly because it’s pretty easy nd I see no reason not to...

i was looking online on different ways to recharge silica, and I read one guys idea was to use a heat gun...I put my wet beads in a stainless pan, and in about 3 minutes, they were dark blue...I used to low heat on the $12.00 Harbor freight heat gun

I wouldn't buy another "cheap" filter like the gold one myself. I had the quick connect crack and spit out the male to male connector fly out past my face at a billion miles an hour. I still can't get the ebay seller to even respond to me about a refund or replacement... so I opened a case with ebay. The filter itself is made of pretty soft metal as well. I bought a better microbore whip for it and when I went to take the original out the threads literally fell apart.. metal shavings everywhere. I am done with it.

The metal of the filter is definitely not hard. I think its 6061 or 6063 Aluminium alloy. Howwever, having the M10 x 1 threads on the end caps falling apart is kind of surprise. I have screwed in and out different fittings a couple of times and I used Loctite 542 sealant instead of the white plastic washer to do the sealing. The Loctite after setting was so hard to be loosen that I had to use gorilla force to unscrew the fittings. The 6mm steel rod inserted into the side of the end cap was slightly bent in the process so you can have an idea on the magnitude of the force I have used. However, the threads still remained in good shape . 

As for the brass connector, I never used it and replaced it with stainless steel type right after I got the filter. 
 
It certainly surprised me a well. They just sort of disintegrated. I have never seen anything like that happen to any other fittings as I too have had to use a LOT of force to get things apart before. I will try and find you a picture. The vendor contacted me and asked me to drop my return and they would send me a new one.. I really don't want a new one, but figured it was not worth the fight and maybe I just got a bad one, so I dropped the return. My guess is i never hear from them again.

If I do get another, I suppose the only thing I can do is load it up with 4500 psi with a cap on the line and leave it for a while and see if it stays together.
 
Coltri has good filters for riund 120 euros from aluminium with fat wall thikness

I am still waiting for photos of the failed gold filter. I own two of them and have for over a year now with zero issues.



Unless I can find real evidence of such a failure and not just a story I will stand behind the gold filters....they are very well made.

I agree with Cherokee140. Titanflyer had a fitting fail, not the gold filter. The "exploding gold filter claim" that was made a few months ago by John from "Navada" was never backed up with any sort of photographic evidence. These things are made every bit as stoutly as any commercial filter housing. Mine is made out of 7075 aluminum which is not the soft 6061 alloy of most aluminum products.
 
....Mine is made out of 7075 aluminum which is not the soft 6061 alloy of most aluminum products.

From the depth of a scratch made my an adjustable spanner wrench on my gold filter, I feel that the metal is 6061 instead of the harder 7075. This is just based on my experience of working on 6061 and 7075 and obviously I can't tell not sure. May I know how you have identified the material ?

I have a feeling like most things along these lines, they are not all made equal....the clone of a clone thing, and that makes it hard for us to know just what is what.

Personally I do believe the chinese will make anything you want to any standard of "quality" you want, and have no doubt that the likes of alpha and diablo are sourced from china. Now do they spin up the machines make more and sell them for half the price....i would bet they do, I would also bet they use other things just this side of PVC. The trick is finding out what to get, where to get, and do our homework. I have no worries on my filter...a gold one, it is very well built and machined very nice....and that is all I can comment on, my sample size of one.
 
I have both the latest Tuxing Gold Filter (purchased Nov/2018 - the one with cartridges) and The Diablo Air Dryer. The walls of the Tuxing Gold filter measure 8mm thick. The walls of the Diablo measure 10 mm thick. The diameter is the same on both (approx 2 inches). Diablo states their unit is made from 6061 T6 aluminum. Overall, the quality of the Tuxing is better than I was expecting. However, I confirmed through AliExpress that the Tuxing is made of 6061 aluminum and NOT 7075 as advertised. I suspected as much. As long as the Tuxing 6061 is heat treated (T6), than the filter should be able to hold decent pressure. The Tuxing came with a very thick Brass foster fitting on the end of the hose. I have never seen a foster fitting that was this thick. Nontheless, it is brass and the internals are unkown, so I will change it if I decide to keep the filter and use this hose. The Tuxing output hose width is similar to the Diablo and the label says it is 630WP and made in Germany. Who knows. One other difference is that the Tuxing end cap sealing o-rings are very thin vs. those on the Diablo. Both the Tuxing and Diablo end caps are tapped for M10x1 fittings.

I purchased the Tuxing mostly out of curiosity and to have as a backup. I have not decided yet if I will keep it. I recently inspected the inside of my Diablo, and after a year of use (albeit light use), it still looks brand new inside. Surprisingly, the molecular sieve was also still fresh.
 
I just joined this group so I hope I am doing this correctly.

My question. Can a Diablo type filter be used as an input air filter to feed a compressor? I have an Omega Super Charger with an Alpha output filter already but thought that adding additional input filtration might have value. I am worried that the Diablo might actually restrict input air and starve the compressor. Any thoughts on this?

Don't waste your money. Those filters are made to extract moisture from air that is under at least 1800 psi. The reason compressors have a Pressure Maintaining Valve is to squeeze out moisture through compression before it exits the output side filter. Think of normal atmospheric pressure as a sponge saturated with water. When you compress the sponge the water is squeezed out under pressure. That's what happens when air is compressed.. The compressor squeezes out the moisture from the air by compressing it. 

Desiccant beads don't work nearly as effectively at normal atmospheric pressure which is what is passing through a filter on the input side of a compressor. Adding the filter on the entry side is just passing the air through the beads and isn't effective. Your input side filter won't do what you think and isn't cost effective.
