Jenny Products Inc. offers a line of electric two-stage, horizontal-tank stationary air compressors. Ideal for applications requiring greater pressure, the line displaces between 9.1 and 107.0 cfm at 175 psi.

Entirely made in the United States, the 22 belt-driven models in Jenny’s two-stage horizontal-tank line provide an extensive range of size and power options. On the smaller end, 2- and 3-horsepower models feature 60- and 80-gallon tanks and displace between 9.1 and 13.4 cfm. Larger units provide 5, 7.5 and 10 horsepower, displace between 18.3 and 43.6 cfm and come with a standard magnetic starter. Tank sizes on the larger end range from 60 to 120 gallons. All models at 10 horsepower or less come in one- or three-phase power.

Two-stage units providing greater than 10 horsepower operate on 208-, 230-, 460- or 575-volt three-phase power and come with 120- or 240-gallon tanks. The 15-horsepower models displace 72.4 cfm, while 20-horsepower units displace 92.6 cfm. The largest units in Jenny’s two-stage horizontal-tank line provide 25 horsepower and displace 107.0 cfm at 175 psi.

Built with quality and durability in mind, Jenny compressors feature a heavy-duty, two-stage cast-iron compressor pump; powder-coated, ASME certified tank; manual tank drain; tank gauge; large canister intake filter with replaceable filter elements and a pressure-relief safety valve. Each unit is splash lubricated with Jenny “Ultimate Blue” Compressor Pump Oil. A large flywheel provides for extra-cooling and easier startup, and special unloading valves further assist the motor in starting. A directional air shroud also helps reduce pump temperatures. The thermal-overload protection feature saves the motor from overheating by preventing it from drawing too much current.


To help maintain consistent pressure levels, an automatic start/stop control with a pressure unloader comes standard throughout the two-stage series. A constant-run feature may be installed instead for those requiring a continuous, heavy flow of compressed air. A dual-control option is offered, as well, which enables the operator to switch between the two configurations as needed.

Additional options include an oil sight glass, low-oil-level switch, air-line filter and control circuit transformer. Adding a lubricator will ensure proper lubrication regardless of air-flow levels for ratchets, impacts and similar tools, while an aftercooler will condense compressed air to a liquid and remove it from the system. Adding a dryer will be beneficial when dealing with water condensation in freezing or high-humidity conditions. Each Jenny compressor also is available in additional pressure configurations.
