F1. Air Fingers
An Air Finger Assembly is made up of three parts:
1. Outer Plate - The Outer Plate is the removable covering
with tapered holes, which direct the air stream onto the
product being baked.
2. Inner Plate -The perforated Inner Plate is vital in forming
the unique air jets. It must be assembled into the manifold
with its holes aligned with the holes of the outer plate.
3. Manifold - The Manifold is the assembly which slides
on tracks into the oven plenum.
