The AirCraft AT0014-37 air inlet regulator is the small control that makes a big difference—allowing you to fine-tune airflow into your 150mm orbital sander for smoother starts, steadier speed, and better control on delicate finishing work.

If your regulator is stiff, leaking, damaged, or the tool feels “all-or-nothing” with no easy adjustment, replacing this inlet regulator helps restore predictable performance and keeps your sander feeling crisp and controllable.
