Standard Air-Blade Air Knife
Air-Blade Air Knife is Cost Effective:
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 a 30" Air-Blade Air Knife 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 equaling $7,187.62 a year.
5. The Air-Blade Air Knife Will Cost: 81 cu. ft./min. X 60 min./hr. X $ .30/1000 cu. ft. X 200 days X 8 hrs/day equaling $2,332.80 a year.
6. The Savings Per Year using the Air-Blade Air Knife will be:
$7,187.62 - $2,332.80 = $4,854.82 per year!
