Your tool. Your working schedule.
Example schedule: 10 trigger seconds each minute. Change it to reflect your job.
Pump duty needs review
Average flow is within the published delivery rating, but burst demand, duty data or operating limits still need checking. This is not a compatibility approval.
Pressure evidence comes from an archived manufacturer document hosted by a distributor. Confirm that your exact unit matches this historical specification before relying on the screening result.
Manufacturer application limits
For referenceNo category restriction is recorded in this dataset. Check the model manual for your application.
Working pressure
Within this criterionThe tool’s 90 PSI requirement is within the compressor’s 125 PSI pressure ceiling. This does not establish pressure delivered through the regulator, hose and fittings.
Air demand versus published delivery
Within this criterionThis schedule averages 3.83 CFM against 5.3 CFM at 90 PSI. This checks average air balance, not pressure throughout each trigger pull.
Airflow during a trigger pull
Check the conditionsWhile the trigger is held, 23 CFM exceeds the 5.3 CFM delivery rating. Stored air may help a short burst, but pressure-switch behavior, burst length and losses have not been simulated.
Pump duty
Check the conditionsA simplified air balance implies 72.33% pump-on time; the recorded duty share is 70%. The estimated requirement exceeds that share. 70% running / 30% stopped across a standard workday; additional continuous-use limits apply. This is not a measured cycle or a continuous-use approval.
Session duration
Check the conditions30 minutes is recorded for your planned session. Model-specific duration limits, cooling breaks and actual cycling are not automatically validated. This field does not change the airflow calculation.
Hose and connections
Check the conditionsThe tool specifies a minimum 0.38-inch hose inside diameter; its recorded air inlet is 0.25 inch. Confirm thread type, coupler profile, hose length and available flow separately; matching nominal sizes alone is not a connection check.
Calculation details
72% estimated pump-on share from average demand ÷ rated delivery. This is an air-balance estimate, not an observed duty cycle or permission to run continuously.
7.1 seconds of theoretical stored-air drawdown over 120 → 90 PSI, with the pump off and a continuous trigger pull. This is not actual operating time, recharge time, or storage life.
Specification screening only. Actual pressure at the tool, hose losses, pump cycling and installation conditions are not established by an average-flow calculation.
What this model page can establish
The recorded die grinder specifications are a starting point for comparing air supply. Select the compressor and working schedule to see each check separately. If you add missing specifications from your manual, the result labels them as user supplied.
Hose inside diameter, inlet thread and quick-coupler profile are separate properties. A matching nominal size is not proof that two fittings connect or can carry the required flow.
