The Single and Two-Stage Duplex Air Compressors from Jenny Products are each equipped with two pumps and two electric motors, which can be operated separately or at the same time. This allows the second pump to serve as a back-up or complement the first pump in order to accommodate greater air flow needs. The duplex compressors are powered by industrial-duty electric motors and come with ASME-certified air tanks. Single-stage models are available with 60- and 80-gallon tanks and provide 19.6 to 55.6 cfm at 125 psi. Two-stage models are offered with 120- and 240-gallon capacities and produce 36.6 to 214 cfm at 175 psi.
