Part# 08-01035
MFR Model# CT850


This new device is a small and very light weight condensation trap. It is used to extract the water from the oil when used in conjunction with the Andair Oil / Air Separator. Water can build up in the engine due to water in the air condensing during a cold night. Overnight this water sinks to the bottom of the sump settling at the lowest point. This is generally where the oil pump pick up is.

Therefore there is a real potential that if one of these devices is not used water can build up in the engine. Flight test have shown that the worst possible condition for water in the oil is on humid days, cold nights and where short flights are undertaken.

Using the CT850 since 2015 in conjunction with the Andair OS850 separator. Mounted the trap at the oil dipstick inspection door on a C-A185F. Super easy to remove the cup, inspect, clean and reinstall. Positive locking mechanism, light finger tight and it is secure. Beautifully machined and finished. Very good product
