If my calculations are correct, that .02 pound difference is a little more than 12% of the water capacity by weight of the media. So it was at 50% of the total rated 25% moisture absorption capacity by weight.

Cool!

Taso

Thanks for doing the math. Very interesting results.

So in this system, 12 hours run time brought the media to half capacity, maybe 20 hours would be a reasonable "maintenance window"?

I intend to bake the same media again for a couple of hours to see if there is any additional gain to confirm the capacity numbers.

Thanks for the info.

Rod

Yeah. It's nice to see results in a real world application versus just reading about them!

Absolutely agree Taso.

Back with a couple more data points.

Tonight I took the same media and cooked it for another 80 minutes at around 500F. The weigh in after was the same as last night's post-cook weight .162lbs. From that I conclude that last night's 40 minute cook got the job done of drying the media out as far as it was going to dry.

Also wanted to mention that the inside of the gold filter tube still looks brand new, no evidence of any issues.

I put the media back into the PVC, replaced the tampon filter plugs, slipped it back into the gold tube and sealed it up. I made note of the media refresh on my Compressor Log spreadsheet, and we are good for another 20 hours.

I used 3mm X 25mm o-rings on mine.

will these o-rings work ?
Silicone 25mm Outside Diameter 3mm Thickness O Ring Seal

Those should be fine. Just don't apply silicone oil/grease. I haven't seen its use mentioned in this thread but everyone uses for other o-rings.

gendoc · « **Reply #64 on:** July 21, 2017, 09:09:09 AM »

my gold filter is arriving today, so i'm ordering the media and orings now before the compressor gets here... whenever

thanks, much appreciated !

I lubed mine lightly just to promote a better seal. Can't tell you if it has any difference over being dry though.

I lightly lube both of my o rings as well. Tighten each end cap of the filter until I think its contacting the o ring, then, tighten each end at little a time until both caps are fully seated.

I think the silicone stops the o rings from grabbing the end cap as it seats...

rnabholz · « **Reply #67 on:** July 21, 2017, 11:01:50 AM »

I agree with a very light lube on the O rings. As you twist the caps on, you run the risk of moving the rings if they "grab" the surface of the cap.

You want the caps to slide across the rings as they are compressed.

gendoc · « **Reply #68 on:** July 21, 2017, 11:08:59 AM »

when lightly lubing the orings, what lube are you using ??

rnabholz · « **Reply #69 on:** July 21, 2017, 11:34:47 AM »

I use a silicone oil.

The Shoebox Max I have uses it to lube the pistons, so it is at hand.

GenDoc. How long did it take for you to receive your filter? I just order mine Monday and it is still in China.

ordered mine on the 17th, DHL should send you a text (if you supplied a cell#)
giving you a waybill# that you can track online.

Yes, using silicone oil/grease is OK BUT he is asking about using it with silicone 0-rings. They don't play nice with silicone oil/grease and will degrade. All these other o-rings y'all are mentioning are nitrile, viton, etc.

Ohhh. missed that. I have never used silicon O rings myself... just regular nitrile Buna 70.

I wonder if there is some kind of coating one could do the inside of the filter with to do away with the pvc?

Not sure why you would want to. The PVC acts as a barrier between the molecular sieve and a space filler which reduces the amount of space that must be pressurized. Win-Win

Ohhh I see I see.

I bought one of the Xin Yong Shi filters for my Carette compressor after reading Rod's post on a different forum. A local friend who recently bought an Air Venturi compressor also ordered the gold filter. Both filters only took a week to arrive from China via DHL. That's faster processing and delivery than I get from most U.S. vendors. I really enjoy reading this thread and appreciate all the ideas you guys are sharing. I set up both filters with 1" endcap sections of tampon cut from the supplied filter material and the 13X desiccant ordered from Rod's recommended Ebay supplier.

When I first read about the PVC liner/o-ring insert hack I made one for the filter while waiting for it to arrive. When it arrived and I realized that there was a noticeable gap between the PVC and filter wall I was concerned that the PVC would either crack due to expansion pressure or leak around the o-rings. My own feeling is that the extremely small amount of moisture that enters the filter through the tiny center entry hole is absorbed by the tampon or 13X molecular sieve and almost no moisture ever contacts the filter walls before being absorbed by the tampon/desiccant. My feeling is that the "toxic acid" created by moisture reacting with the desiccant which will eat through the anodized coating, aluminum walls, and threads of the filter is mostly marketing hype. The vendor who sells $400 filters and $40 filter replacement packs is not an unbiased source of the gospel when it comes to facts about filters. The Xin Yong Shi filter is nearly identical to the Diablo filter sold by AofA which does not use cartridges and also uses desiccant beads. No one using Diablos has ever reported any sign of chemical reactions or exploding filters.

I'm not advocating anyone removing their PVC inner liners from their filters. It doesn't hurt anything and it provides you owners with a level of comfort which I understand and appreciate. I will monitor my filter and report my findings as a source of information
and sharing of ideas on another approach. If I see any chemical reaction to the anodized coating or threads I'll report my feedback.

If it turns out that a liner is necessary I've also researched a local aluminum tubing distributor which sells 1.375" outer diameter, 1.250"ID pipe. My digital caliper won't reach far enough inside the filter to give me an exact reading but if it fits it would be a more
precise fit to the 1.250"OD PVC you guys are using. If it works I was thinking of getting enough of them made up to provide to Xin Yong Shi filter owners who might be interested. I'm just not sure how necessary they are.

Has anyone found a way to get the exact inner dimension of your gold filter housing?

A telescopic gauge would work. I don't have any though.

Harbor Freight has them too.
