5. SDT North America4 How Much? Cost Per YearSize $ 8,382.001/4” $ 2,095.001/8” $ 523.001/16”

6. SDT North America5 Air Leak Cost Calculator

7. SDT North America6 For best results follow these recommendations Data Input: Green Cells are designated for data entry. The more precise data you provide the more accurate your calculator will be Begin with the first worksheet called “Compression Cost” There are two ways to use the calculator Worksheet 2 “air lost per orifice” Worksheet 3&4 “costing using dBµV” Worksheet 5 “Total Leak Cost” must be done only when the plant is in shut down and real air demand is zero.
