Tough and durable, built on the industry-standard G3400 platform bring maximum uptime and low operating cost to your operation. G3408 engines meet the most demanding continuous duty gas compression applications with virtually no unscheduled downtime. Ideal applications for G3408 engines include gas lift, gas gathering, and wellhead gas compression. Cat G3408 gas engine. Ratings: 190-298 bkW (255-400 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
- Improved 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 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
GERP is a PC-based program designed to provide site performance capabilities for Cat® natural gas engines for the gas compression industry. GERP provides engine data for your site’s altitude, ambient temperature, fuel, engine coolant heat rejection, performance data, installation drawings, spec sheets, and pump curves. Product Support Offered Through Global Cat Dealer
