After searching for a large capacity, proper “Vortex” style catch can for years, we finally made our own to our specifications.
8″ tall, 3″ diameter, holds .25 gallons or about 1 liter. Large 1″ inlet and outlets for free breathing. 1/4″ NPT outlet drain.
Vortex design means incoming gasses hit round cylinder wall being forces to spin in a “vortex”, centrifugal force causes oil and water particles to fling outward and drain down the walls to be collected or returned to the sump.
The outlet on the can extends down 4″ inside the can to create a baffle and prevent incoming fluids to being expelled directly out of the can.
This breather can is recommended for all high performance applications to remove oil vapor from the intake tract.
Sold in a black powder coated finish.
