Re: Installing 250 Cfm Compressor Into Enclosed Trailer


Okay, so it is going slower than I had planned. There are so many little things that have to be done.

First off I got my equipment today!! Once I get a few more parts ordered for the trailer I'm good to go.



Here is a picture of the gas cap on the outside of the trailer:


Here is a picture of the improvements on the inside of the trailer. I decided to install the after cooler on top of the oil cooler. This way it won't be blowing its hot air into the motor as it would have if I mounted it by the console. It's hot air will blow out the front of the trailer much more easily. My Dad is a plumber and he is going to run large copper pipe from the air supply, back to the after cooler, and back up to the front for easy connectivity. Having this extra length of pipe should also help in the cooling of the air not to mention it will be nice having it plumbed instead of hoses all over the place.

I'm considering two different options for exhausting the heat out the tongue side of the trailer. One would be to get a 2'x4' baggage door for an RV trailer and install it ($80). I would obviously have to open and close it each time I use it, but it would flow very well. The second choice I have a friend looking into. We thought about install a 3'x3' or larger louvered vent that opens from the pressure of the fans blowing. This would require less on my part and might look cool. I'm waiting to see costs.

You can see in the picture how the exhaust will vent through the roof. I'm still waiting for the flex piece to arrive (it isn't clamped down so yes I know it isn't straight). This may not serve a purpose, but I think it will look cool and it might bring in cooler air... On the 2 air intakes, I'm installing large PVC pipes and basically creating air scoops that will face the rear of the trailer. I figure it might help keep the air flow smoother. The engine fan, oil cooler fan, after cooler fan, and air intakes will all be pulling air exactly the same direction from the rear of the trailer. In the picture you can see the start of the install of one of the air intakes, it will be cut shorter, elbowed and come towards forward a foot or so.

Also new in the picture the dashboard is installed. Nothing fancy, but it should do its job nicely. I'm also going to install toggle switches to power the after cooler fan and the dead man switch power. You will also notice that I started tinkering with where the hoses will hang and figuring out how/where I want to mount the pot. Also you can see the gas tank is installed too. Like I said it is moving slower than anticipated, but it is coming along.

Re: Installing 250 Cfm Compressor Into Enclosed Trailer


I think I would put a removable wire or old chain fence around the motor.
have heard horor stories about people geting cloths or arms cought in the motors while running.
if you was blasting, who know who might go into the trailer when your not looking.

would keep things from getting in there to, rags drop cloths etc..

my brother ownes a lobster boat, the owner before him lost his arm trying to tune the engine. (got a good deal on the boat)

How are you going to run your air hoses and fuel fill? Did you mount that air cooler back there? I agree, unless you keep your air hose hooked up all of the time from that coolers current location, you are playing with fire!! Those engines aint no joke...Just worried you will walk back there to hook up a hose while the engine is running and like Jim said, it will pull you in..

What if by some strange reason OSHA is in the neighborhood? I know it is 10000000000000000000000000000000:1 odds but, what if? LOL

Re: Installing 250 Cfm Compressor Into Enclosed Trailer


Hopefully OSHA is mostly conceren for employee saftey. They might not go over board on an owner operator? But then I doubt we are suposed to repaint anything we blast at at home and you just have to hope the epa or whatever doesn't come around for that either.Sometimes this whole business seems to be about hiding from the law while you just try to earn a living.

Re: Installing 250 Cfm Compressor Into Enclosed Trailer


Two angle bars from the control panel to the front
Old chain link fence hooked to it.
Maybe some on top??

I don't think it would be hard.

Besides the OSHA thing (employees only)

Insurance reasons, what if..... Is there motto

If you blast alone, like a lot of us. You rely on the hope that nothing goes wrong while you’re blasting.

I have stopped blasting, turned around to check on my compressor, and there is 3 people standing there watching.

Now I put up cones and Caution Tape if I'm in a bad location. So no one gets hurt and sues’ me for injury!

if the person your working for, gets board, roams around while your blasting, want to check out how things work,
lets see how the air compressor works Bla Bla Bla...
It does happen.

2 cents worth, maybe 3

Re: Installing 250 Cfm Compressor Into Enclosed Trailer


The air hoses are all going to be plumbed in copper pipe back up to where the original air service pipes are (near the console). So that portion will be hooked up all of the time. I won't have to ever have to go back there except to service the compressor.

The fuel hose connection is still in my mind. You can see the fuel tube right by the fill tube on the gas tank. I think it will be as simple as cutting a hole an additional filler neck just for the new fuel tube. Or perhaps putting the fuel tube right into the original filler neck (It fits perfectly).

You guys are right on safety. I think it can be a little simpler though. I really will have no reason to go behind the console except to service the compressor. I like the chain link idea. I could just put a 7' length of chain link from one side of the trailer to the other, with a cut out right around the console controls and a second cut out around the service air outlets.

Maybe something like this:

Re: Installing 250 Cfm Compressor Into Enclosed Trailer


Just build you a simple wall in front of the compressor. You can place a vent in the wall for your incoming air and your control panel can be mounted in your wall so all you have to do is to go into the room before you start your compressor to check all your fluid levels like your suppose to before you start any equipment. This would cut down on the noise in the rest of your trailer a lot. and make it look cleaner as well. Throw in some chain link fencing and you might as well place a few chickens in the coop as well.

Johnny,

Can I ask where you found your 250cfm for $2900?? That's awesome.

Re: Installing 250 Cfm Compressor Into Enclosed Trailer


On the local free online classifieds. It belonged to a contractor that got it as part of a package deal about 5 years ago when he bought some big equipment. I guess he was about to go through a divorce and never really used it (a little bit for some jack hammers and his brother used it a little to blow out sprinklers before each winter). He tried to get more, but not many people responded. It seemed like he was just trying to get rid of his extra worth before the divorce

All I know is it would make the back part of the trailer look and sound much better. All of your polyurea rigs has the Generator set up front and isolation wall between the front and back. Helps to keep everything quite. Also on the same wall you can put a work bench with cabinets top and bottom and really utilize the space of the wall. Your instrumets are mounted on the wall and you can start the equipment from there as well. Just a suggestion is all. A few 2x4's, Good insulation and some plywood and paint would make it look factory.

Re: Installing 250 Cfm Compressor Into Enclosed Trailer


would overheating be a issue with the insulated wall?
even with vents I wonder if you could get enough cool air flow.

Is it serviceability or looks you’re going for.

you would loose a lot of room next to the motor (In Green), plus motor service would be easier to.

blocking it off would look good, but your in it to be mobile. you need every inch for tarps, rope, signs hoses, shovels, blast pot, grit, hoods, blast cloths, boots etc... room on a far away site is a must. extra stuff some times is a must.
think about it before you do anything... ASK YOUR DAD find out what he thinks..

Re: Installing 250 Cfm Compressor Into Enclosed Trailer


Dyer,

You would not loose any of the room. All the are up front would still be there and usable. The engine would still be servicable as well. Plus all the tarps, hoses and other stuff would be out of sight as well. As far as cooling goes, it would not be a problem with the right size vents. All of the Polyurea rigs that are out there is like this and they have up to 80 KW Generators mounted in them and the space is smaller than what he has and they cool with no problem. One thing to keep in mind is you need as much intake as what you have as outake. So your vents need to be the same size.

Re: Installing 250 Cfm Compressor Into Enclosed Trailer


I agree that the wall would look good and clean!

the wire around the motor would only be for protection (for people and the motor) so things would not get sucked in by mistake. or if you didn't clean out the area before starting the motor...

Benny , I had wondered if anyone else did this with no over heating problems.
a gen that size puts off just as much heat.
air in = air out

thanks for the input!

Re: Installing 250 Cfm Compressor Into Enclosed Trailer


One other thing. There is no exposed fan on the motor and the fan on the oil cooler for the air end is enclosed in a enclosure so there is no chance for a person to get sucked in and spit out. The only exposure would be the belts driving the Alt. and the engine fan. One other thing. If your planning on wearing a Air Fed Blast Hood, I would suggest you place your air intake somewhere else other than thru the roof with your exaust. Doing this would allow the intake to pull your exaust fumes which would contain Carbon Monoxide into your breating air and the outcome would not be good. Also, If you plan on breathing from this aircompressor you chould be running a CO monitor anyway. You cannot only get CO from the Exaust but from the Air end as well from over heating the cooling oil and that process will give off CO as well and that goes straight into the air stream.

Re: Installing 250 Cfm Compressor Into Enclosed Trailer


I believe my Airman comes with an overheat auto shut down. Is this something that can be retrofited to an older compressor? Any one ever try this?

Re: Installing 250 Cfm Compressor Into Enclosed Trailer


I like your setup. It is very similar to mine. I have a Soda Blast System 200 Pot, Clemco 3 bag media pot and a Sullair 250CFM Compressor. I need to build a air dryer though. im probably going use use an air to air aluminum intercooler with a high cfm fan. One question though, does your set-up have a desiccant dryer of some sort? I just see the aftercooler, and water/oil filtration. Thanks, and good luck...

EDIT I think I see a desiccant filter on the bottom right of the last photo..Can you confirm? Can you let me know if it has a model, numbers of flow rating on the filter? Thanks
