What size compressor do you really need? CFM cheat sheet
Why HP lies, how to add up tools, duty cycle and why a 120-gal tank saves motors…
We are St. Louis Pneumatic Store — the Midwest's working warehouse for rotary screw & piston compressors, pneumatic tools, FRL, fittings, hose and aluminum piping. 4,500+ parts on the shelf, factory-trained techs, and 24/7 emergency repair from Forest Park Ave to Metro East.
Founded in 2007 in a brick garage off Forest Park Ave, stlouispneumaticstore.net grew into St. Louis's independent headquarters for compressed air. We supply auto shops on Cherokee, cabinet makers in Maplewood, food plants in Earth City and maintenance crews at the breweries — anyone who can't afford to lose pressure at 2pm on a Friday.
We don't just sell boxes. We size systems, crimp hoses while you wait, rebuild pumps, run ultrasonic leak surveys, and install clean, sloped aluminum loop piping that drops your energy bill 18–31%. Every counter person wrenches. Every tech is factory-certified on Quincy, Ingersoll Rand, Atlas Copco, Kaeser and Campbell Hausfeld.
Brass, stainless, DOT, high-flow couplers, regulators, lubricators, filters, reels, hose, dryers, drains.
Pump rebuilds, VFD retrofits, dryer service, piping installs, PM with oil analysis.
We right-size HP, kill artificial demand, fix leaks — then sell you less compressor.
Net-30 for shops, fleet discounts, jobsite delivery across STL metro in 90 min.

“Our 15HP screw died Friday 4pm. They had a loaner running by 6:30 and new VSD installed Tuesday. Saved our powder-coat schedule.”
“Leak audit found 38 leaks. Air bill dropped, compressor cycles half as much. Paid for itself in 4 months. These guys measure, not guess.”
“Counter rebuilt my 3/4 impact same day, crimped two hoses while I waited. Real mechanics, not salesmen. My only air supplier now.”
