What is the Brabazon Toolbox?
Seventeen working calculators for compressed air systems, industrial pumps, and equipment operating cost. Every tool shows its math and uses realistic industrial defaults. Estimates only. For exact sizing, call 800.825.3222.
Compressed Air
Air Compressor Sizing Calculator (CFM and HP) Add your air tools and duty cycles to get required CFM and a recommended HP class. Open the calculator Pressure Setpoint Savings Calculator Lower your PSI, lower your bill. See what a lower setpoint saves per year. Open the calculator VSD Compressor Savings Estimator Estimate the energy savings of a variable-speed drive versus a fixed-speed compressor. Open the calculator Air Leak Cost Calculator Estimate the true financial impact of untreated air leaks based on count or total horsepower. Open the calculator Air Receiver Tank Sizing Calculator Size a receiver tank for your demand swings and compressor output. Open the calculator Compressed Air Pipe Sizing and Pressure Drop Calculator Check line sizing and estimate pressure loss across your distribution piping. Open the calculator SCFM to ACFM Converter Convert standard vs actual flow for your elevation, heat, and humidity. Open the calculator
Pumps
Pump Sizing Calculator: Flow, Total Head, and Horsepower Add static lift, discharge head, and friction losses to get TDH and motor HP. Open the calculator NPSH Available (NPSHa) Calculator Check whether your suction conditions give the pump enough head to avoid cavitation. Open the calculator Pump Affinity Laws Calculator: Speed and Impeller Trim Predict flow, head, and power when speed or impeller diameter changes. Open the calculator Pipe Flow Velocity Calculator (Liquid) Check line velocity against suction and discharge guidelines for your flow. Open the calculator
Cost of Ownership
Air Compressor Energy Cost Calculator Estimate annual electricity cost from horsepower, load, and run hours. Open the calculator Pump Operating Cost Calculator See what a pump costs to run per year and what a worn pump is wasting. Open the calculator Compressed Air Downtime Cost Calculator Estimate what an unplanned compressed air outage costs per event and per year. Open the calculator On-Site Nitrogen vs Delivered Nitrogen Calculator Compare delivered cylinders or dewars against generating nitrogen on site. Open the calculator Utility Rebate Estimator (WI, IL, MN, MO) Get a planning-level rebate range for compressed air efficiency projects. Open the calculator Rent or Buy? Compressor Rental vs Purchase Calculator Compare rental against ownership cost and find your break-even month. Open the calculator
Looking for the flagship sizing tools? The Tools page has the CFM calculator, the leak cost estimator, and the rent vs buy comparison, with the same formulas-in-the-open approach.
These are estimates. Your system has the real numbers.
