|shine||if not pvc then copper but there will be no iron pipe in my shop. it rusts then holds moisture and oil vapors which end up in the booth.|

|shine||will likely be copper or pet . sch80 pvc is some pretty tuff stuff.like i said it has been in every shop since 78. i just want that loud aggravating compressor up the hill in it's own little building. tired of hearing it.|

Shine, When ya do it go copper inside.
In my new shop, ran copper 3/4 (almost 300 linear ft) with all fittings for less than $250.
Just my 2 pennys

sch 80 pvc is pretty tuff. i have had sch40 in the shop for 13 years. when i move the compressor in the fall i will replumb the shop. from compressor to the shop will be pvc underground. have not decided on what will go in the shop yet. pvc / pet /copper will be the choices. abs for air is higher than copper.
my compressor will still be set at 80 lbs.

Shine, you asked why I run 175 PSI and I only have one lame answer: That is what the pressure regulator is set at. The 80 Gal tank and and 120 feet of delivery line that is all inside the walls and 2 100 ft hose reels provide a pretty good reservoir of air. My sand blaster is a el cheapo pressure feed unit that hold 100#s of sand. I set the regulator at the hose reel at 100 psi and the compressor cycles through out the blasting period. I have not had a moistur problem blasting since I have 4 5 foot drops with drains, a moisture separator and a toilet paper filter before the hose reel. I have never gotten water from the last two drops and very little from the moisture seperator which is between #2 and #3 drops. All my air tools are set for 90 PSI and the plasma cutter is usually around 70 plus or minus 5 pounds operating pressure. I have a couple of 20 ton air jacks and I turn them up to 120 on occasion. I use 110PSI on the air jack on my lift (operating manual suggestion). So you can see I don't need the 175 PSI. I would like your and oldred's inputs on the merits of turning it down ie energy savings, less wear on pump etc.

We are OK.... I wouldn't say I have 100% dry air,, But it isn't really to bad being as hot as it is here.... I just finished shooting the frame for the train I'm doing... IT'S HOT !!!!
It make make a big difference that my new compressor isn't a year old yet.... I don't think it is anyway..
And I do know what you and oldred was trying to prove here.... ''Safety''

My opologies, sounds like everybody has dry air. I noticed a little moisture in my lines a couple weeks ago, so I upgraded to the three stage dryer from Sharp. I never used the shop so much in the summer until the last couple of years. So now I have 100% dry air.
I saw a Porchdog post for Hub back in o4or o5, but sometimes we forget how helpful old friends can be.
Hope I didn't offend anyone, I just want everybody to be safe, and work to the best of their ability. And I have enjoyed and learned a lot from both you guys.

my blasting rig is completely separate. it is a diesel powered compressor . has 2 moisture traps.
the reason for moving the compressor is because i am tired of hearing it. by moving it up the hill i can plumb underground to the shop using the earth temp to cool the air before it enters the shop. this will be pvc . my booth is about 100 ft of air line from the compressor right now. have a good trap in the booth followed by a toilet paper filter. no water problems except for days where any air movement will create moisture period. if the shop floor is wet from the air forget it. do something else.
i've know hub aka dr.gun for a long time .

It stay's very hot down south, 100+ here all the time..
Chevymon...I'm not convinced at all.. This would fall under starting something...Don't start !!!!

|oldred||Shine probably knows more about media blasting than anyone here and is a pro using pro quality equipment I am sure. Like I said I don't know how his air supply is set-up but likely it is one the largest (if not the largest) systems that any of us here have and I am certain it works properly, I never intended to question that.|

Sorry if I misread your comment intent. I saw a post from shine on another forum, and he was talking about running pipe underground soon, so I think that means he is having trouble. And with the blasting that he does, it could be very aggravating.
He shares so much, it would be nice for him to recieve once in awhile, nobody knows it all. But if he is reading the comments from Hub, it should put him in the right direction.
|08-31-2011 12:54 PM|
Not sure what you mean but I was not being sarcastic, I have known Shine for a while and he really is a professional who could not put up with a moisture problem. I am certain he does not have one but I don't know how his system is set up so I am curious how he accomplishes this.
