The EC99S Twin Stack Compressor features an oil-lubricated cast iron pump and 15 Amp direct drive induction motor for longer life. The motor is protected by a thermal overload protection that stops the motor in a possible overheating situation. Weighing just 52.9 lbs, the EC99S has an ergonomic carrying handle to make it easier to transport to any jobsite. A universal quick coupler and steel encased industrial gauges are factory installed on the unit so it is ready to go out of the box.
