Radium Engineering Air Oil Separator AOS-R Universal VTA - 20-0819

Radium Engineering 20-0819 universal Air Oil Separator-Return (AOS-R), VTA (vent-to-atmosphere) version.

• VTA (vent-to-atmosphere): clean crankcase air exits through a slotted, baffled top
• Two side inlet ports suit dual-bank engines with two crankcase vents. On single-vent engines one inlet can be plugged with Radium 14-0351
• Outlet is much larger than the inlet bore, which slows airflow so contaminants can settle out
• Diffuser traps oil sludge and returns it to the can, reducing overspray in the engine bay
• Dual-stage design (inlet and outlet chambers) with no meaningful flow restriction
• Not recommended for MAF sensor engines, because the vented design creates an air leak
• Inlet and return/inlet ports are 7/8-14 threaded for 10AN ORB fittings
• Coolant port is 7/16-20 threaded with two 7 mm (5/16 in) barbs

Included

• Machined aluminum AOS-R unit
• Aluminum mount that rotates 360 degrees
• Two 5/16 in barbed coolant fittings
