The EC99SM twin stack compressor features an oil-lubricated cast iron pump and 15 Amp direct-drive induction motor for long 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 EC99SM also comes with an ergonomic carrying handle, making it easy to transport around any jobsite. A universal quick coupler and steel encased industrial gauges are factory installed on the unit so it's ready to go right out of the box.
