    2. Motor ships pre-wired for either 208–230 V or 460 V, 3-phase, 60 Hz.
    3. Horsepower: 7.5 hp on the narrow 50-88 model; 10–15 hp on wider 60/96-inch tables.
    4. Airflow is roughly 900–1,300 cfm at 60–80.-H₂O static pressure.
    5. Sufficient to keep a 12- to 15-ft table fully evacuated even with the foam kerf gap open.
    6. Medium-pressure regenerative blower (centrifugal side-channel style).
    7. Dry-running, needs virtually no maintenance, can pull 70-110 in-H₂O (≈18–27 kPa).
