Evac Oil Separator Tank 3in x 4in

The Evac Oil Separator Tank 3in x 4in by CHAMP PANS is a compact air-oil separation system designed for engines requiring efficient crankcase evacuation and vapor management. This unit addresses the critical need to separate oil mist and contaminants from intake charge air, preventing oil carryover into the intake manifold while maintaining proper crankcase ventilation. Builders and performance technicians rely on quality separator tanks to extend engine life, reduce carbon buildup, and protect downstream components in modified and high-performance applications.

Constructed from durable aluminum in natural finish, the Evac Oil Separator Tank features a compact 2.5-inch-wide profile with dual 12 AN male fittings for inlet and outlet circuits, plus a 1/4-inch NPT female fitting for breather or vent applications. The separator's internal baffling design passively removes oil particles and moisture from crankcase vapors through centrifugal separation and gravity settling—no moving parts or maintenance required. With dimensions of 4.75 x 3.25 x 6.7 inches and a lightweight 0.72 pounds, this tank integrates easily into tight engine bay layouts without sacrificing separation performance or flow capacity.

This separator tank benefits forced induction builds, road racing engines, and any application where PCV system cleanliness impacts reliability and longevity. The dual AN male ports accommodate standard braided lines and fittings, allowing seamless integration into custom intake manifold vacuum circuits and catch-can systems. Installation requires only basic hose routing between the crankcase vent source and intake manifold vacuum port, with the NPT fitting available for secondary vacuum draw or catch-can overflow routing. Verify port sizing and vacuum requirements before assembly to ensure optimal airflow and oil separation efficiency in your specific engine configuration.
