Natural Gas Engine-Driven Air Compressor Advisor

The Natural Gas Engine-Driven Air Compressor Advisor is an analysis and reference tool intended to help with the evaluation and selection of gas-powered air compressors. It is targeted at industrial applications and covers air compressors in the approximate size range of 50 to 500 horsepower.


Energy International developed the software under the guidance of the Energy Solutions Center Air Compressor Consortium. The Consortium participants helped ensure that essential calculations are computed accurately by this powerful, yet easy-to-use economic decision analysis tool. The results have been validated against several real-world examples.

The Air Compressor Advisor is organized into three sections: Manufacturers, Case Studies, and Economic Calculations. The Manufacturers section contains a database of company listings and product offerings (color photographs of products are included when available). The user has the ability to customize this database by adding, deleting, or modifying entries.


The Case Studies section contains several examples of sites that have benefited from the installation of gas engine-driven air compressors. Like the Manufacturers section, the user can customize the database by modifying, adding, or deleting information. The Economic Calculations section is comprised of two calculators: Quick Economics and Detailed Economics. The Quick Economics calculator allows the user to perform a quick screening to compare engine-driven and electric motor-driven air compressors. The Detailed Economics calculator allows the user to perform a thorough site-specific analysis by setting variables such as time of operation, part load efficiency, detailed gas and electric rates, capital or lease purchase criteria, and capital and maintenance costs.

All members of the Air Compressor Consortium can download a free copy of the software (14MB). Follow the instructions in the self-extracting downloaded file for registering the software with Energy International and obtaining the code number for activating the software.
