10°CGTA47-55
Since 1953, Garrett has pioneered the development and application
of low cost, high perfomance turbochargers with robust design, high
temperature capability and wide compressor ranges.
Incorporating an upgraded bearing system, designated for maximum durability, and the latest aerodynamic improvements, the Garrett GTA47 through GTA55 turbochargers are custom matched for comercial applications to 700 hp. Recent developments in aerodynamic design allow for an inertia reduction of up to 25%. Recent upgrades for improved resistance to external loads, high degree of commonality of components and overlapping characteristics afford great design flexibility.
All models use patented, boreless compressor wheel technology to increase compressor wheel life at high pressure ratios.
