Compressed Air Blow Off System Is Cost Effective
Example Of An Air Saving Calculation
-
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.
-
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.
-
From the compressed air consumption chart , a 4" diameter Ring-Blade™ consumes 49 SCFM at 60 PSIG.
-
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!
-
The Nex Flow™™ 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!
-
The Savings per year using the Nex Flow™™ System will be:
$2,923.78 - $1,411.20 = $1,512.58 per year!
