  1. Manufacturer application limits

    For reference

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

  2. Working pressure

    Data missing

    The tool’s operating pressure has not been confirmed. A pressure value is needed before its airflow can be matched to a compressor rating.

  3. Air demand versus published delivery

    Data missing

    No confirmed compressor delivery point matches the unknown tool pressure. Ratings at another pressure are not interpolated.

  4. Airflow during a trigger pull

    Data missing

    At-load flow and a same-pressure compressor rating are needed to screen demand during a trigger pull.

  5. Pump duty

    Data missing

    The recorded duty share is 70%, but demand data are insufficient to screen pump load. 70% running / 30% stopped across a standard workday; additional continuous-use limits apply.

  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.

Evidence still needed

  • Confirmed tool operating pressure
  • Compressor delivery at the tool’s confirmed pressure

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 sander 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.
