Airflow difference
Both publish 5.3 CFM at 90 PSI. Choosing the larger tank does not increase that delivery rating.
10020C VS 20020
More tank, the same published airflow
A 10- versus 20-gallon choice. Compare the storage difference without treating it as a larger pump.
| What to compare | 10020C | 20020 |
|---|---|---|
| Air delivery at 90 PSI | 5.3 CFM | 5.3 CFM |
| Tank volume | 10 US gal | 20 US gal |
| Duty share | 70% — see manual | 70% — see manual |
| Published noise* | 70 dB | 70 dB |

| Weight | 82.5 lb | Not confirmed |
| Supply voltage | 110 V | 110 V |

Storage difference
The tanks are 10 and 20 US gallons. Over the same pressure interval, stored free-air volume scales with tank volume. Recovery time also depends on delivery across that interval and is not inferred here.
Limits that remain part of the choice
10020C: 70% running / 30% stopped across a standard workday; additional continuous-use limits apply.
20020: 70% running / 30% stopped across a standard workday; additional continuous-use limits apply.
- Listed SKU is 10020C-3 while product/model name is 10020C. Record follows model name. Do not equate 125 PSI tank maximum with delivered airflow at 125 PSI.
- Product feature list says 114 lb; additional-information table says 115 lb. weightLb is null pending confirmation.
- Product page describes 90–120 PSI working pressure, ±5 PSI; maximum tank pressure is 125 PSI.
CHECK THE PAIRING
Your tool. Your working schedule.
Example schedule: 10 trigger seconds each minute. Change it to reflect your job.
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 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 3.67 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 conditionsWhile 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 criterionA 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 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
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.
7.4 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.
