The EC28M is Hitachi's first quiet compressor that features an industrial oil-free pump that not only provide high durability, but also delivers maintenance free operation. The motor is protected by an overload protection circuit that cuts off power in the case of an overload situation. Weighing just 25.2 lbs. and designed with an ergonomically shaped rubber carrying handle, the EC28M is easy to transport around any jobsite. The steel roll cage protects the steel encased industrial gauges and all other critical components. The EC28M has a zero set-up time, and is ready to plug and play straight out of the box.
