Industrial Air IH1393075 13-HP 30-Gal. 2-Stage Truck Mount Air Compressor w/ Electric Start Honda Engine features an OHV design for increased efficiency and optimal power transfer. EPA and CARB-approved, it includes an automatic low oil shutdown feature to avoid unnecessary damage to the unit due to user error. Industrial-level performance delivered maximum CFM at 175 PSI, providing enough power to operate more than 1-air tool or device at 1-time. Our patented pump design provides for a cooler running pump. This is due to our unique, patented piston design, our cast iron cylinder head with patented deep-groove directional cooling fins, precision-bored cylinder with patented asymmetrical cooling fins. Perfect for service truck and field service applications, it also features a patented cast iron flywheel design, along with a 30 Gal. truck mount style ASME-certified tank. The 7.5 Horsepower, cast iron, 2-stage industrial pump features six free-floating stainless red valves with stop guides for controlled lift, along with 4-rings per piston for improved volumetric efficiencies and oil control. Our patented piston design allows for improved compression efficiency. We extended the height on the already high-efficiency breather, and the large, easy-view oil level sight glass eliminates guesswork.
