HornBlasters 1HD Heavy Duty 12V DC Air Compressor | 100% Duty Cycle at 100 PSI | 150 PSI Max, 1.80 CFM | Onboard Air for Train Horns, Air Suspension | Replaces John Deere AA72119

The HornBlasters 1HD is a heavy-duty 12V DC air compressor built for people who actually use their onboard air systems. Whether you're running train horns, airing up tires, or powering air suspension on trucks, Jeeps, SUVs, UTVs, and RVs, the 1HD delivers where cheaper compressors fail. The standout feature is the 100% duty cycle at 100 PSI. At pressures up to 100 PSI, this compressor runs without needing cooldown periods between cycles. Most compressors in this price range tap out around 30-50% duty cycle, leaving you waiting for your compressor to cool down before you can use it again. Specs-wise, you're looking at 1.80 CFM at 0 PSI, a max working pressure of 150 PSI, and the ability to handle tanks up to 5 gallons. It draws 23 amps on a 12V system. Dimensions are compact at 10" x 3.93" x 6.75" and it weighs 10.4 lbs. Everything you need for install is in the box: stainless steel braided leader hose with check valve, two-stage air filter, snorkel kit, spare filter elements, and mounting hardware. Use thread sealant (not thread tape) when installing fittings. Recommended torque is 10-11 ft-lbs for 1/8" fittings and 12-15 ft-lbs for 1/4" and 3/8".
