Jenny Products Inc.’s single- and two-stage duplex compressors are equipped with two pumps and two electric motors that can be operated either separately or simultaneously. This can allow the second pump to serve as a backup or to complement the first pump when accommodating greater airflow needs. The compressors come with ASME-certified air tanks. Single-stage models are available with 60- and 80- gallon tanks, and two-stage models are offered with 120- and 240-gallons tanks. Options include an oil slight glass, dryer, aftercooler, lubricator, air line filter, circuit control transformer, and low oil-level switch.
