Each of the line’s 16 models encompass a smaller footprint than their horizontal-tank counterpart while maintaining the quality and durability of Jenny’s complete compressor inventory of more than 175 units. Each compressor uses a heavy-duty, two-stage cast-iron pump and powder-coated, ASME certified tank. A large flywheel provides for extra-cooling and easier startup, while special unloading valves further assist the motor in starting. A directional air shroud helps reduce pump temperatures, and a thermal-overload protection feature prevents the motor from drawing too much current and overheating.
