Out side car port air tank

General rule is don't expose your cylinders to weather/temp/humidity changes. If you full out your tanks, say to 4500psi and leave it to mid day heat it will be far harsher for the cylinder and gauges.

I have overfilled my Acecare 9L to above 5000psi by leaving the compressor for too long. The tank took it fine but the compressor disc deformed so there is that.

I might make a box under the bench that holds the bottle while I am out there, but I don't think I would want to leave it out there. Temp swings, moisture, UV, and who knows what else will probably affect it for the worse. Id just carry it out there. A $40 used 80cu ft aluminum scuba tank I might be more partial to leaving out under a bench. But not a CF bottle. 

In a fairly well sealed box out of direct sunlight I would think it would be OK so long as there are no thieves around.

Modern Carbon fiber resins and coatings contain UV blockers and are just about indestructible and impervious to UV degradation. The valves are made from stainless steel and brass. Leaving something that is designed to withstand extreme harshness out in the weather will have no structural effect whatsoever. Natural sunlight will never produce enough heat for overpressure to cause any SCBA or SCUBA bottle to fail no matter what it is made of. Do you think that a fireman would walk into a burning building if he thought that the bottle on his back was going to explode from the heat? As for the gauges. If they are SCUBAorSCBA type then no problem. As for some of the cheaper Chinese or paintball stuff, if kept out of the rain, then they should probably be OK. Bugs, dust, or spillage won't harm anything other than maybe an exposed O-ring.

i wouldnt want to leave a tank out in the open ..wind up with a dirt dobber nest right in the valve lol .. or a squirrel might chew something like gnaw your knob off .. then you got to declare war and it gets ugly lol ..

I think as long as you kept the tank from direct sunlight like in a box with some insulation to keep the temperature swings smaller you would be just fine. It may have a UV coating but may not be a good quality coating. I've seen what the sun can do to resin left in direct light for a year and it was not pretty. The temperature swings would possibly work harden the aluminum liner with has a bigger cte than the carbon fiber. 30+ years working with aerospace composites testing and fabricating.

Carpenter bees around here would fill the hose end with dirt. Event the drain holes for the vinyl windows gets packed by the little devils.

I would have to agree with those remarks about the the sun killing things. Keep it out of the sun. Put a cover over it. 

Thats a sweet setup. Nice and simple.

Where did you find that pump and how high can it pump

That is a big sucker of an desiccant filter mate!

Good on ya.



I'we seen that kind of compressor. Old naval diving specs something that illudes me for now?



Dont overthink it, go wtih your thoughts.

As said, CF bottles are made to survive the heat of a fireman going into a blazing fire for 45-60min and survive.
