Compressor and air dryer setup

S

silflexer

So I just picked up a 80 gallon single stage air compressor and a smc 25 cfm refrigerated dryer off of craigslit. The setup came with a pile of 1" flex line and 1" quick disconnect-couplers. Cool stuff but I am not sure if I can utilize the 1" or not. I just have a home hobby shop and paint, sandblast, etc on occasion. Any reccomendations on if I should use this fancy flex line? Anyone with experience with these air dryers that has any advice before I jump into my setup? Thanks in advance.
 
I would call a compressor company and see about those lines!!!! If not right can be very dangerous like using PVC, over the years many have been killed or injured.
Osha might be worth a call as they have gone in shops and gave them 30 days to re-plumb the PVC and a fine on top of that.
 
The flex lines are a braided, very high end style that were installed in a major defense contractors shop. I will get the name and part number off of them to verify they allowed for this use. Thanks for the heads up!
 
I run a pair of 2 stage compressors with the pressure switches slightly offset. 90% of the time only one compressor runs, if I am using a lot of air the second compressor will kick in and help. I have them tied into one feeder line that enters 2 stages of oil/water canister filters before going into a hankison refrigerated dryer. I am currently regulating pressure at the inlet of the dryer, about 120 psi. Out of the dryer my air splits off in different directions. I go 3/4" to my main feeders for shop tool air and I have a 1/2" that goes to my booth. Outside of my booth I have a sharpe 3 stage cleaner/dryer with desiccant. I follow the desiccant with a motorguard sub micronic filter, then I go through the wall into the booth with Milton V style fittings and a 3/8" hose.

I'm happy with my setup except I need to add one more regulator, then I can move my current regulator to the post dryer position along with another. (one for my booth feeder and one for my shop air lines.) I want to cut my shop air back to 100 psi but I'd like to leave my booth feeder at around 125.

I guess I'd only use enough flex to get from your tank to your hard lines.
 
Those 1" lines are nothing to shy away from providing they meet code for compressed air and the pressure rating is not exceeded. The more volume you have in your air line, the more natural cooling you have, the more moisture seperated from your filters if you have it plummed correctly.
 
Those 1" lines need to be terminated correctly if they are not already otherwise all hell can break loose. That drier is a nice one I've been eyeballing those and Hankinson. What make is the compressor?
 
I bought a 1" steel braided hose to connect to my compressor tank it isolates the vibration of the compressor to the hard line, it wasn't cheep I think $60 or $80 for 1.5ft terminated, so depending on how much you got with the package and if it is the same type hose you might have some money there.
 
I get back home on monday and will see what this hose is. The couplers are very nice so I imagine this stuff isnt cheap.

I think you are referring to whats on the end of a 1" pipe and the potential hazzard of an end cap blowing off? My lines are the 1" thick wall copper. Both ends point down at the floor with a shut off valve so I can open them to drain moisture. The copper pipe collects a lot of water and I drain it after every use. I go forever on my inline filters and have very dry air without an air dryer.

No i am refering to the flexable lines. I could have bought some heavy duty rubber lines but my compressor friend and neighbor who ownes a Co. that deals with high pressure both told me not to make anything myself because of the dangers involved. So I bought a manufactured flexable high pressure air line from my compressor friend, it is steel braided on the outside and heavy reinforced rubber inside with high quality ends properly terminated. It is also the kind of line you would want to connect two compressors or another tank with so the vibration doesn't eventually crack lines or fittings.

Looks real close to this.
 
Ok looks like I have Parker series 7092 line with crimped fittings. I will use the flex line from the compressor to a coalescent filter and them the dryer. After that I will use the remaining flex hose and run it up along the rafters to a final regulator/filter setup and a hose spool. This is definitely overkill for my little shop and given that humidity levels here are almost always very low here.
 
New to the Forum and SPI and Painting. Been teaching myself on HF guns and a cheap 20 gal compressor over the last year. Finished my updated air supply a month ago.

60 gallon Craftsman Prof, out to press regulator, out to the first dryer, out to 40 feet of black iron pipe 0.75" diameter. Ends at a second dryer and desiccant dryer, out to my hose. Got this setup idea from a few body shop buddies. So far working great. start spraying the Supra this weekend
 
The last stop on my multi-filter setup is the orange Motor Guard D-12 in-line filter at the gun inlet. It's rated to trap down to .01 microns.
Cheap insurance against any possible hose contamination too.
