20020CR
air-supply check.

The continuous-run version trades a higher published noise figure for a 100% duty rating and defined long-duration limits. Its 90 PSI output is 5.0 CFM, slightly below the standard 20020's 5.3 CFM.

California Air Tools 20020CR

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.

  1. Manufacturer application limits

    For reference

    No category restriction is recorded in this dataset. Check the model manual for your application.

  2. 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.

  3. Air demand versus published delivery

    Within this criterion

    This schedule averages 3.67 CFM against 5 CFM at 90 PSI. This checks average air balance, not pressure throughout each trigger pull.

  4. Airflow during a trigger pull

    Check the conditions

    While the trigger is held, 22 CFM exceeds the 5 CFM delivery rating. Stored air may help a short burst, but pressure-switch behavior, burst length and losses have not been simulated.

  5. Pump duty

    Within this criterion

    A simplified air balance implies 73.33% pump-on time; the recorded duty share is 100%. 100% duty; duration limited by pressure. This is not a measured cycle or a continuous-use approval.

  6. 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.

  7. 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

73% 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 20020CR publishes 5 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.
