- SCFM - Standard Cubic Feet
per Minute
A standard cubic foot of air is the amount of air contained in one
cubic foot of volume when the air is measured at standard conditions of
pressure, temperature and relative humidity. There are
several different standards that can be used. Toward
compressed air applications a commonly used reference is measured at
sea level atmospheric pressure (14.69 PSIA), 68 degrees Fahrenheit and
a relative humidity of 36%. At these standard conditions, one
cubic foot of air weighs 0.075 pounds. If the temperature
goes up, this standard cubic foot of air will occupy more than one
actual cubic foot of volume. SCFM is a measurement of weight
(mass), regardless of volume.
|
|
| |
|
|
- ACFM, ICFM, FAD &
CFM – Actual Cubic Feet per Minute, Inlet Cubic Feet per Minute, Free
Air Delivery and Cubic Feet per Minute
All of these terms are based to the same idea. They refer to
a volume of air at ambient conditions or a referenced set of inlet
conditions. Changes in atmospheric pressure, temperature or
relative humidity do not affect these ratings. These are
references of volume without regard of mass or weight.
These references are used as brochure capacity performance
figures. They represent the amount of air drawn into a
compressor at a defined operating speed. Compressor manufacturers can
play games with these ratings by measuring these volumes at different
points in the compressor package or under conditions that are different
from actual ambient conditions.
|
|
| |
|
|
|
If a compression application is expressed in
SCFM, the brochure capacity must be mathematically corrected to
standard conditions.
