Just got a CH 60 gallon upright. 7HP (so they say). To go from empty to 135 psi takes about 6.5 minutes. Is this a normal fill rate? Just wondering.... Cheers! /// unsubscribe/change address requests

Well, I used to know how to do this ... a cubic ft is 7.48 gallons, so your 60 gal tank is about 8 cf. Atmospheric pressure is about 15 psi, so you've got about 9 atm * 8 cf or roughly 72 scf. Divide

Yeah Randall you still know how to figure out something.... LOL... but his fill TIME is going to be the relationship of that CUBIC foot of area to the size of the compressor's cylinders / RPM / and i

same size compressor, (porter cable), and the fill time is approximately the same as you stated. Also, thanks to Keith for his insight to my concrete question. Tom /// unsubscribe/change address req

This is the least reliable specification. A more accurate horsepower rating could be calculated by taking the steady-state ampere rating from the motor plate. Volts time amps gives you watts, and a

Except that electric motors aren't perfectly efficient, and generally don't have perfect power factors, so volts times amps isn't necessarily watts. 1000 "volts times amps" (1kVA) per horsepower is

Thanks. I know the HP rating is as bogs as a shop-vacs - was only referencing it so you'd know the model/type of a/c. Yeah, an IR would be nice but it's just me in the garage... :-) At 03:31 02/17/20
