The charts below give air consumption at various pressures for typical open jets and similar data for Air Jets and Nozzles. From this data, air cost savings obtainable through conversion to Air Jets or Nozzles can be easily calculated.

Example:
Existing blowoff is 1/8" open pipe at 100 PSIG supply. Air consumption, from the chart, is 85 SCFM .

Use a Model 1001 Air Nozzle, 1/8 NPTF also at 100 PSIG supply. Air consumption, from the chart, is 12 SCFM.

Compressed air saved = 85 - 12 = 73 SCFM.

For this example, the blowoff is continuous. If the duty Cycle was 20%, then air saved would be 73 x .2 =14.6 SCFM.

Most, large plants know their cost per 1000 standard cubic feet of compressed air. If you don’t know your actual cost per 1000 SCF, 25¢ is a reasonable average to use.

Dollars saved per hour = SCFM saved x cost/1000 SCF x 60 min = 73 x .25/1000 x 60 = $1.10/hour
$1.10/hr is $44.00/week and
$2,288.00/year savings.

Metric Example:
Existing blowoff is 1/8" (3.2mm) open pipe at 6.9 BAR supply. Air consumption, from the chart, is 2406 SLPM.

Use a Model 1001 Air Nozzle, 1/8 NPTF also at 6.9 BAR supply. Air consumption, from the chart, is 340 SLPM.

Compressed air saved = 2406 - 340 = 2066 SLPM.

For this example, the blowoff is continuous. If the duty cycle was 20%, then air saved would be 2066 x .2 = 413 SLPM.

Most large plants know their cost per 10,000 standard liters of compressed air. If you don’t know your actual cost per 10,000 SL, 8.9¢ is a reasonable average to use.

Dollars saved per hour = SLPM saved x cost/10,000 SL x 60 min = 2066 x .089/10,000 x 60 = $1.10/hour. $1.10/hr is $44.00/week and
$2,288.00/year savings.
