Spal 30100375 12-Inch Straight Blade Puller Fan - High Performance Cooling Fan for Automotive, Radiator, and Industrial Applications

Compact enough to fit in the small space that I have but it delivers a great deal of cooling power to the air compressor after-cooler that I fabricated using copper pipe and heating fin element. It may be running on 7 amps but it will need a 20 to 30 amps converter to get it started, my first 10 amps choice converter didn’t have enough juice for it.
