Raven Inverted Oil System

Oil pressure is critical to aircraft engine operation and longevity!  An aircraft engine draws its oil supply from a sump via an oil pump and pick-up tube.  Oil must be available at the oil pump pickup tube at all times.  If at any time there is no oil available at the oil pick-up tube there will be immediate loss of oil pressure and no oil will be circulated through the engine. The Raven Inverted Oil System is designed to address this problem.

If you are getting tired of cleaning the belly of your aircraft when only performing positive “G” aerobatics, and do not require a full inverted system we offer the air/oil separately. (Coined the “Half Raven System”). By installing the separator only you will reduce the amount of oil vented overboard substantially! 

On the other side of that we offer our Extreme system, this includes our extra large oil/air separator if you like performing extreme air show type aerobatics! 

Our inverted systems now feature an improved CnC machined valve.

We have designed sump fitting kits for all of the stock and aftermarket sumps available today. For stock angle valve sumps we offer an extended fitting for better oil pickup, we also offer an option for K series sumps.

We offer our standard air/oil separator in 2 different sizes (4″ or 5″ dia) to suit your specific application.
