Ingersoll Rand duplex reciprocating air compressors offer two individual compressor pumps and two motors mounted on a single tank, providing 100% built-in backup or additional air power for those larger capacity jobs. The Duplex is ideal in applications where available power does not allow for a single larger compressor. The latest generation of Ingersoll Rand duplex reciprocating compressors has the legendary Type 30 pump with value added features in a space saving design suitable for those tight spaces. The duplex packages are available in Value and Premium configurations with factory fitted options ready-to-use.
