Ingersoll Rand's T30 family of reciprocating two-stage air compressors, from 5 to 20 hp (4 to 15 kW), feature precision engineered, two-stage cast iron pumps for superior reliability in continuous duty applications. The ultra-rugged pump construction reduces the risk of downtime. The compressors utilize individually cast cylinders, an overhung crankshaft and a one-piece connecting rod, which combine to provide quick and easy maintenance. A low oil level switch shuts down the compressor when necessary to prevent it from causing damage by running without lubricant.
