 Air-Blades
Are Cost Effective
EXAMPLE OF AN AIR SAVING CALCULATION
1. From the above 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 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 NEX
FLOW™ Air-Blades 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 NEX
FLOW Air-Blades
will be $7,187.62 - $2,332.80 = $4,854.82
per year.
