Continuous Air Pressure

I need to be able to push about 30~40 psi non stop. For like 24 hours straight. Im also poor and cant afford giant tanks or continuous 100% duty cycle compressors.
I havent done all the math for my project to know the cfm yet and before I go down that road of setting up an apparatus, I wanted to know if there was a way of maybe combing 2 air compressors and having them run in succession (not simultaneously) to get around the duty cycle thing. Or maybe some other tool altogether

    Oh my, what an interesting problem! Naturally, the solution would be to

    Oh. I see.
    Welp, guess you're fricked.

    Depends on the volume of air you're moving at that pressure, so you really need to figure that out first. If it's low, a single b***h compressor like you pictured will work. It'll run, fill the tank up to 120 psi or whatever it's rated, and the regulator will restrict outflow to the 30-40 psi. Once it hits it's low setting, the compressor will run again. It's not continuous. If you're worried the compressor is too small, pick up a bigger one used. You can also plumb a large storage tank in before the regulator so that the compressors runs longer but not as often.

    The only way I can see using two compressors like you're talking about is if you had two outlet timers that you could set to each stay on for 20 minutes or something on opposite schedules. That way one compressor would get power and run, then the other one would. Timers like that might exist for lights but they might not handle the load from the compressor.

      Wouldtn do that.
      These cheap compressors are designed to run the time they need to fill the original tank.
      They overheat easily when they run a little longer than they should.

        Use surface agitation, not continuous compressed air. Gonna cost you less.

    Use PVC pipes for your 40 psi tank

    What is the flow demand?
    A) multiple airpump in parallel. You may find pump with broken vessel cheaply and do the piping. Cheap junks probably won't run for that long.
    B) a turbocharger's compressor side may generate this much pressure ratio when spun high rpm, think 80k to 180k rpm, radius and material dependent. Subsequently a high rpm motor, a shaft to replace the one from the turbine, and oil supply.
    What is this air for anyways?

    I mean, as long as your volume requirements aren't too crazy, you should be...

    Never mind, this is a troll.

    you could build your own from an old car engine.

      This is the best idea.
      Simple too disable an injector and put a hose on it.

    Even picrel makes 20 PSI. Just find a blower that will do > 30 PSI.

    just put your air compressor in your fridge.

    What's your flow and honestly why the hell would you need a 40psi positive vent? You are probably making your application more expensive than is necessary
