Airflow difference
At 90 PSI, the published delivery changes from 0.7 CFM on the MAC100Q to 2 CFM on the MAC210Q. Compare those ratings with your tool’s at-load demand and usage pattern.
MAC100Q VS MAC210Q
Two Quiet Series sizes
Compare capacity and portability within the manual’s nailer/stapler application limits.
| What to compare | MAC100Q | MAC210Q |
|---|---|---|
| Air delivery at 90 PSI | 0.7 CFM | 2 CFM |
| Tank volume | 1 US gal | 2 US gal |
| Duty share | 50% — see manual | 50% — see manual |
| Published noise* | 58 dB | 60 dB |
| Pump type | oil-free | oil-free |
| Weight | 27.6 lb | 45.2 lb |
| Supply voltage | 120 V | 120 V |

Storage difference
The tanks are 1 and 2 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
MAC100Q: No more than 50% compressor pumping time within each hour (owner manual).
MAC210Q: No more than 50% compressor pumping time within each hour (owner manual).
- The shared owner manual restricts applications to properly rated nailers and staplers. A flow calculation must not override this restriction.
- Weight conflict: product overview says 25.5 lb; product specifications and owner manual agree on 27.6 lb. Record uses 27.6 lb.
- The shared owner manual restricts applications to properly rated nailers and staplers. A flow calculation must not override this restriction.
- Weight conflict: overview says 44 lb; product specifications and owner manual agree on 45.2 lb. Record uses 45.2 lb.
One or both models have captured manufacturer application restrictions. The matcher reports these before an airflow result can be treated as a reason to select the model.
CHECK THE PAIRING
Your tool. Your working schedule.
Example schedule: 10 trigger seconds each minute. Change it to reflect your job.
Outside stated application
The manufacturer application limit is a deciding constraint for this pairing. Airflow arithmetic does not override it.
Your average air demand3.67 CFM10 seconds of trigger time per minute · 1 tool · 30-minute session
Published compressor delivery0.70 CFMAt 90.0 PSI
Manufacturer application limits
Does not meet this criterionThe captured manufacturer guidance limits this compressor to nailer / stapler applications. This tool is categorized as impact-wrench. A favorable airflow calculation does not override that restriction.
Working pressure
Within this criterionThe tool’s 90 PSI requirement is within the compressor’s 135 PSI pressure ceiling. This does not establish pressure delivered through the regulator, hose and fittings.
Air demand versus published delivery
Does not meet this criterionThis schedule requires 3.67 CFM on average, above 0.7 CFM published at 90 PSI. A larger tank alone does not close the ongoing air-supply deficit.
Airflow during a trigger pull
Check the conditionsWhile the trigger is held, 22 CFM exceeds the 0.7 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 523.81% pump-on time; the recorded duty share is 50%. The estimated requirement exceeds that share. No more than 50% compressor pumping time within each hour (owner manual). 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
524% 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.
0.7 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.
