Description
Mark Ironair 20HP Duplex Industrial Compressor
The Mark Ironair 20HP Duplex is a flagship reciprocating system designed for high-demand industrial environments requiring maximum air volume and built-in redundancy. By utilizing two 10HP motors and dual cast iron pumps on a single 120-gallon horizontal tank, this system delivers an impressive 70 CFM at 175 PSI, ensuring that even if one pump requires maintenance, your facility remains operational at 50% capacity.
Thermal efficiency is managed through finned aftercoolers and a low-RPM pump design that reduces mechanical stress and noise levels. Selecting industrial reciprocating air compressors from the Ironair Duplex series provides a reliable, pre-wired solution with magnetic starters and oversized intake filters to maximize volumetric efficiency in dusty workshop conditions.
