Abstract
An air motor apparatus for air drilling includes a filter assembly at an uphole end that receives compressed air and diverts a constant pressure portion through a filter to a vane motor and a remaining portion to an air hammer at a downhole end via bypass conduits. The apparatus includes one or more sensors for measuring drilling conditions, the sensors being connected to a communication device capable of transmitting the sensor data to the surface. The sensors and their wiring are shielded from high air speeds by bypass conduits and components of the filter assembly.
