California Air Tools

20020
air-supply check.

Twenty-gallon reservoir stores twice as much tank volume as the 10020C, but its published 90 PSI flow is identical. A larger tank extends a burst, not sustained pump capacity.

Usage conditions need 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.

Manufacturer application limits
For reference
No category restriction is recorded in this dataset. Check the model manual for your application.
Working pressure
Within this criterion
The 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 criterion
This schedule averages 3.67 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 conditions
While the trigger is held, 22 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
Within this criterion
A simplified air balance implies 69.18% pump-on time; the recorded duty share is 70%. 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 conditions
30 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 conditions
The 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

69% 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.

14.9 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.

Reading the result for this model

The 20020 publishes 5.3 CFM at 90 PSI. The matcher compares a repeating trigger schedule with a delivery point at the tool’s confirmed pressure. A passing average-flow check does not establish outlet pressure throughout a burst.

Tank volume affects the amount of air stored between two pressures; it does not change the published pump delivery. Review the optional buffer estimate separately from duty and session limits.
