Airbrush Compressor Pressure Gauge Tip
Posted by Strongeagle on Monday, August 12, 2019 9:03 AM

I bought a Paasche D3000r compressor/tank several years ago.  Its a nice compact unit, doesn't make too much noise, the compressor sits on top of a small tank, and the unit sits on the floor by my workbench.  The specs say it puts out 0 to 40 psi, auto shut-off is at 50 psi, and that's OK because I use 10 to 25 psi consistently in my painting.  HOWEVER: The gauge that came with the unit reads from 0 to 150 psi!  The increments are so small I can hardly see them, let alone get an accurate reading.  I went on ebay and for less than $10, bought a pressure gauge that reads 0 to 30 psi and replaced the one that came with the compressor. I can see the readings now without having to bend down for a closer look and can make mico-fine pressure adjustments.

That's a problem with a lot of instruments. The scale is often too large and generally the the greater the span the less accurate. A thermometer, for example, that covers a huge range is no good to me when it's accurate only to a couple percent of the scale.

A number Army Viet Nam scans from hundreds yet to be done:

Have had the great fortune to be on every side of the howitzers.

Check Amazon for a 30 psi gauge  I output my compressor at full pressure through a second regulator with the 30 psi gauge    I can regulate the pressure with finer control    ive read that big box store pressure gauges can be off 10% max scale

A local air products supply house may have something  but it may be more $
