The exclusive sizes of the Setrab ProLine Super Standard oil cooler were selected for their broad range of system applications, so it seems a natural progression to utilize them in these highly versatile super fanpacks. The SSTD oil coolers are able to perform at a greater capacity within a smaller footprint due to the modification of the internal turbulators. This results in an increase of the internal surface area, allowing for greater cooling capacity per cubic inch, all while maintaining superior flow and optimal pressure drop that the world has come to expect from a Setrab oil cooler. Both super-cooler fanpacks are compact, high-performance units, perfect for transmissions, differentials, and engine cooling applications. The powder coated steel shrouds include integrated mounting tabs (including 70A durometer rubber pads) that allow for rigid, face mounting, isolating the aluminum core from chassis shock and vibration. 6.5" Spal puller fan(s) (p/n: FAN30103084) 330 CFM @ 0 static pressure (per fan)12V brushed motor (each). Setrab ProLine oil coolers feature low-profile M22x1.5 female ports, adaptable to any common size you may need using SUSA ProLine Adapter Fittings.
