Weighing less than 53 pounds and featuring an ergonomic handle, Hitachi’s EC99S air compressor is easy to transport around the jobsite. The 4-gallon twin-stack unit has an oil-lubricated cast-iron pump and thermal overload protection for the 15-amp direct-drive induction motor. The compressor can run multiple nailers depending on the application, by offering 3.1 cfm at 90 psi and 3.05 cfm at 100 psi. The locking regulator and 105 psi-on/135 psi-off pressure switch means users won’t have to worry about pressure wander or pressure-starved tools. Other features include a ball-valve drain cock, shock-absorbing feet, and a factory-installed universal quick coupler. Priced at $200. hitachipowertools.com
