*PEEK Bearing Wear Surfaces:

* The DFS780 spur gears ride on PEEK (Polyether Ether Ketone) bearing surfaces to reduce both noise and wear.

*Contoured CNC Machining Of Manifold Passages:

* Enhances flow through the manifold to reduce pressure drop due to flow restrictions.

*Direct Bolt-on Steel Mounting Bracket:
