Air-Blade™ Air Knife - Cost Effectiveness

Example of an air saving calculation.

1. From the chart showing air flow through a hole, assume we have a pipe 30 inches long with 1/16" holes spaced ½” apart with a total number of 59 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 59 X 4.23 = 249.57 SCFM.

3. From the compressed air consumption chart for Air-Blades, a 30" Air-Blade™ Air Knife System consumes 2.7 SCFM per inch or 30 X 2.7 = 81 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 Pipe Will Cost:
249.57 cu. ft./min. X 60 min./hr. X $.30/1000 cu. ft. X 200 days X 8 hrs/day = $7,187.62 a year.

5. The Air-Blade™ Air Knife System Will Cost:
81 cu. ft./min. X 60 min./hr. X $ .30/1000 cu. ft. X 200 days X 8 hrs/day = $2,332.80 a year.

6. The Savings Per Year using the Air-Blade™ Air Knife System will be: $7,187.62 - $2,332.80 = $4,854.82 per year!
