They are built for efficiency and lower operating costs, producing more compressed air at a lower horsepower. They run at a slower RPM, run cooler and cost less to operate. Heavy-duty compressors are engineered for industrial applications and boast an industry-leading 50,000-hour pump life rating. One-year limited warranty without extended warranty kit purchase.
