    I posted this in case anyone is considering buying a Bostitch 6 gal 150psi compressor to supply air to a ShoeBox.

    I bought this early Dec of 2018 to replace an older Craftsman 3 gal 100psi compressor that I initially bought to keep my car tires aired and to blow out my desktop computer. The old compressor had problems with car tires and barely made it thru one desktop blow out.

    I can say the Bostitch fills those old needs nicely but I found that when using it as an air source for the ShoeBox — it fails miserably. With the regulator set at 90-95psi and a 'duty cycle' of about 1 minute to fill the tank from 120-150psi and a little over 4 minutes to reach the starting point where the motor starts again, after about 1.5 to 1.75 hours it starts a fast 'duty cycle' (fast cycle) barely reaching 122psi before starting over. I found turning it off and on, the regular 'duty cycle' ran for several cycles but started the fast cycle again shortly afterwards.

    The following day I took it to a warranty shop near by and after 1.5 weeks called for a status and they said they found nothing wrong. I picked it up and later the same day started the operation again to finish topping off my tank but once again it started that fast cycle routine at about the same time frame. Back to the warranty shop I went  and after a rather long but cordial conversation, I was told they couldn't help. It was designed for "light" work and not extended running times. They then gave me the customer support number and said they would do what the customer support folks said.

    I called customer support today and they listened to my story then after inquiring with others familiar with this compressor — said basically the same thing. It was not designed for longer run times. They were willing to give me a phone number of the main compressor technical support but if they agreed to look at it, I would need to ship it to them. I didn't keep the box and it is heavy so thats not an option for me. I would guess the shipping charges would be about 1/3 the value one way.

    Bottom line — I'm on my own. I did see what the motor looks like while at the warranty shop and the fan that cools the motor is directly connected to the motor itself. Any heat created while running that is still there once the motor shuts off has to disipate on it's own.

    I don't want to let it run without my being within ear shot as it is (basiclly baby sitting) but I might try forcing air thru the intake area to see if that helps since the fan don't run without the motor. If that don't help I may look at other options or simply sell this to someone local needing air for short running times (ie: trim work).

    I will post this on several forums.

    In the late 90's I was helping a friend doing cedar shakes, we were shooting two finish air nail guns running off a 15 amp generator in the middle of a farm field. The compressor ran all day for weeks. It was a porter cable 6 gallon. Fully expecting it to die with the 40 plus square that was installed I bought a second as a back up. It's still going strong today.

    I have a Jun Air oil free quiet compressor for paint jobs and I once had the idea of using it to drive the ShoeBox but finally gave up because the ShoeBox has some requirement on the pressure and flow rate of the first stage compressor. My Jun Air just doesn't meet the flow rate requirements. From your description, it seems that your compressor does not have enough flow rate as well.  The compressor going "fast cycle" suggests that it cannot keep up with the rate of air drawn by the ShoeBox. The Freedom 10 requires a first-stage compressor that can deliver compressed air ( 90 psi ) at 3 cubic feet per min. but it seems that your Bostitch can only do 2.6 as indicated in the official site : 

    My compressor, it can do 2.12 cubic feet per min :

    How about one of these. Harbor Freight Fortress 2 gallon 1.2 HP 135 PSI Ultra Quiet Oil-Free Professional Air Compressor. Very quiet, Puts out 2.1 SCFM at 90 PSI.

    Mine shuts off at 135 PSI and comes on at 90 PSI.

    Airgunfans, you should use your Jun Air.   A Shoebox is not an airhog like the Altaros booster compressor.   I first used a Porter Cable 6 gallon pancake compressor with my F8 but it was too loud for me so I replaced it with a quiet running Rolair JC-10.   Shoebox F10's sip air and your low run cycle with the Jun Air will pleasantly surprise you.  I'd set the Jun Air regulator for 125 psi and see how long it runs to keep pace.  It will not be stressed at all.

    This is the one I use with the F-10. Runs till it fills up and holds for about 10 min. Before starting back up again.  H F has then on sale now. Sale price is the same as using their 20% off coupon.

    According to the Q&A section of Shoeboxcompressor.com's official website, Tom Kay states that the F10 requires a compressor with an output rate of 125 psi and 2 cfm.

    A quick update on my attempts to use the Bostitch compressor with my upgraded Shoebox booster.

    Several days after my initial post on the matter, I set up a controlled bleed to mimic the dury cycle seen so far but this time I had a small fan blowing into the intake grill of the Bostitch. I don't believe having the fan as part of the motor is a good design for extended run times since there is no cooling done at when the motor is not running and I believe using an external fan blowing into the intake  should show improvement.  I tested temperatures off/on and didn't see any temps to be alarmed about and it ran for 4.5 hours without issues. I can make this work using an external fan.

    Given all the replies I have got on several forums, one reply stated they had an older Bostitch and had no issues (same internal cooling design?), plus many of the replies thought leakage is causing a loss of air which in turn shortens the duty cycle, more investigation was needed. Well — yesterday I tested all connections before the Shoebox and did find multiple leaks (sigh). It took some time but I think I got all the leaks addressed.

    I hooked up my full tank (valve closed) and fired up the Shoebox. I got to 4600psi pretty quick and once it shut down, let it sit for about 5 minutes monitoring the tank gauge during that time and pressure remained at 4600psi.

    More lessons learned and I want to say thanks to those who took time to reply — much appreciated…
