 EXAMPLE
OF AN AIR SAVING CALCULATION
1. From the chart
showing air flow through a hole, assume we have a circular
tube that is 4" in diameter. It has a circumference
of 3.14159 X diameter or 12.57 inches. Assume it has 1/16"
holes spaced ½” apart with a total number of
24 holes. The air pressure in the system is 60 PSIG.
2. From the chart
each 1/16" hole consumes 4.23 SCFM at 60 PSIG.
Total air consumed is 24 X 4.23 = 101.52 SCFM.
3. From the compressed
air consumption chart for Ring-Blade™,
a 4" diameter Air Ring-Blade™
consumes 49 SCFM at 60 PSIG.
4. Assuming a compressed
air cost of 30 cents/1000 standard cubic feet and an 8 hour
day operation for 200 days per year, the drilled circular
tube will cost: 101.52 cu. Ft./min. X 60 min./hr. X $.30/1000
cu. Ft. X 200 days X 8 hrs/day = $2,923.78 a year.
5. The Ring-Blade™
Air Blow Off System will cost:
49 cu. Ft./min. X 60 min./hr. X $ .30/1000 cu. Ft. X 200
days X 8 hrs/day = $1,411.20 a year.
6.
The savings per year using
the Ring-Blade™
Air Blow Off System
will be
$2,923.78 - $1,411.20 = $1,512.58
per year.
