Ajax Advantages
• Reliability – Proven two-stroke design ensures reliable
operation
• Availability – 98% or better availability providing increased
revenue and production time when properly maintained and
operated
• Operating Efficiency – Integral net compression efficiency is
greater due to low mechanical losses when compared to non-
integral technologies
• Fuel Flexibility – Ability to operate using a wide variety of fuel
gases, including sour gas up to 3.0 mol%
• Ease of Installation and Mobility – Plug-and-play flexibility
combined with the ability to relocate based on
field life
• Low Total Cost of Ownership – Lower overall operating
costs due to fewer parts, slower speed and proven design

Slow-speed Separable Compressor
For more than 50 years, Ajax integral engine-compressors have
earned a reputation for being as reliable as any compressor
product, through efficient and long-lasting service. Our product
line – from 147 to 845 hp (110 to 630 kW), with a cylinder lineup
capable of handling a wide range of pressures – offers up to six
ratios of capability and a lower brake horsepower (BHP) per million
flows for a wider range of applications.
AJAX integral technology provides lower overall operating costs
and maintenance expenses. Improvements over the years have
added to the strength and simplicity of the original design.
