Tough and durable, built on the industry-standard G3400 platform bring maximum uptime and low operating cost to your operation. G3406 engines meet the most demanding continuous duty gas compression applications with virtually no unscheduled downtime. Ideal applications for G3406 engines include gas lift, gas gathering, and wellhead gas compression. Cat G3406 gas engine. Ratings: 160-242 bkW (215-325 bhp) @ 1800 rpm are NSPS site compliant capable with customer-provided air-fuel ratio control and aftertreatment or available for non-regulated areas. Engine Design
Proven reliability and durability - Ability to burn a wide spectrum of gaseous fuels - Robust diesel strength design prolongs life and lowers owning and operating costs - Broad operating speed range Emissions
Rich burn engine design easily meets emission requirements - 0.5% O2 rating meets U.S. EPA Spark Ignited Stationary NSPS Emissions for 2007/8 and 2010/11 with the use of aftermarket AFRC and TWC Full Range of Attachments
Large variety of factory-installed engine attachments reduces packaging time Testing
Every engine is full-load tested to ensure proper engine performance. Gas Engine Rating Pro
