Claim:
1. An apparatus for directing pressurized air comprising: a body for receiving pressurized air, the body including opposing side walls, a top surface joining the opposing side walls, a first end joining the top surface and the opposing side walls, a second end joining the top surface and the opposing side walls, and an exit opening defining an elongated shape bounded by the opposing side walls, the first end and the second end, where the opposing side walls converge toward the exit opening at an effective angle of convergence, and where the opposing side walls and the first and second ends define a body shape which causes the pressurized air to follow an airflow path which includes a 90 degree turn as the pressurized air flows from an air inlet location out through the exit opening; at least one interchangeable nozzle insert configured to match the elongated shape of the exit opening, the at least one interchangeable nozzle insert positioned within the exit opening by means of at least one fastener which passes through the at least one interchangeable nozzle insert and the opposing side walls, where the pressurized air can exit the body substantially only through the at least one interchangeable nozzle insert, where the at least one interchangeable nozzle insert includes a plurality of discharge orifices for directing the pressurized air outwardly from the body, and where each of the discharge orifices includes a conical portion for receiving the pressurized air from the body, each of the conical portions having an opening angle which is within a predetermined range of the effective angle of convergence of the opposing side walls, and each of the discharge orifices further includes a cylindrical portion for directing the pressurized air outwardly from the body; and at least one air inlet, the at least one air inlet suitably attached to the body for directing the pressurized air into the body.
