Choose a compressor based on data, not guesswork. You’ll calculate the required FAD flow, the minimum receiver tank size for peaks, the risk of restriction (throttling) in the hose, and the cost of compressed-air leaks. You get a result and a short sizing recommendation.
A receiver tank helps during peaks. It won’t replace capacity for continuous operation. If a tool runs for long periods without breaks, compressor flow (FAD) is the key.
Start with flow. Then verify the buffer (tank) and the installation (hose). Finally, check leaks — that’s the fastest win on operating costs.
Add your tools. Set duty cycle. Set simultaneity. Add a safety margin. You get the required FAD flow. You get a compressor type recommendation.
| Tool | Flow | Unit | Work pattern | Duty [%] | Qty | Remove |
|---|
You calculate required flow from tools, then add simultaneity and a safety margin. You get FAD to compare against a compressor.
If semi-continuous work dominates, the calculator will show higher Q and suggest stable operation. The result uses the spray gun spec sheet (DTR) flow.
No. Here you calculate flow demand. Check pressure drop in the hose calculator.
It’s the real amount of air delivered to the system. It’s the most important parameter when sizing a compressor.
A tank buffers peaks. It does not replace capacity for continuous operation. Here you calculate the minimum tank volume for a given time and allowable pressure drop.
Here you calculate minimum volume for a chosen time and pressure drop. This is a buffer. It is not “compressor capacity.”
No. A tank helps in peaks. For continuous work, you need higher FAD.
There is no pressure reserve. Then the tank does not “give” any air. The result does not make sense.
Yes. If the compressor refills during the event, the required tank volume is smaller.
Enter flow, hose length, and internal diameter. You get a status: OK, risk, choking. You also get a recommended diameter.
If flow is high, increase hose ID. Shorter hose helps. Quick couplers also matter.
Yes. A longer hose increases resistance. Pressure drop rises.
No. This calculator covers the hose. Fittings can worsen the result. Treat a “risk” status seriously.
The tool gets less air than it needs. Torque drops. Speed drops. Cycle time increases.
Choose a method. Calculate leaks from a pressure-decay test or from an “orifice”. You get annual cost and a repair priority.
First calculate leak flow. Then compute power loss using specific power. Then compute cost from kWh and operating hours.
It’s good for audits. It works if you isolate consumers and measure decay over a controlled time.
It’s a quick estimate. Good for priorities. It does not replace a flowmeter measurement.
How many kW you use per 1 m³/h of compressed air. It simplifies cost calculation for losses.
Provide a tool list. Provide simultaneity (% overlap). Provide hose lengths. - You’ll calculate better. You’ll choose faster.
