Atlas Copco’s GAR 5-37 oil-injected, air-cooled screw compressors are designed for dedicated railway applications. They are proven reliable, compact, low weight and low noise machines. The GAR 5-37 range has a long and successful history of meeting the most demanding compressed air requirements of main line locomotives, heavy-duty diesel locomotives, shunters, EMUs, DMUs, metros and LRVs.
The GAR screw compressor helps railway operators to achieve punctuality and reliability, while reducing operational costs.
Reliability – The GAR 5-37 range is a simple, highly reliable compressor package design. It incorporates a minimum of moving parts, a shaft-driven cooling fan, corrosion-resistant materials such as stainless steel and aluminum, and rigid and sturdy construction to withstand external vibrations, dust, exhaust gases, shock loads and projectiles. These compressors perform in temperatures from -40°C/-40°F to +50°C/+122°F and are designed to withstand the most extreme weather conditions.
Maximum uptime – The GAR 5-37 range is characterized by long service intervals requiring an absolute minimum of maintenance. This guarantees an availability of more than 99%. Over a total lifetime of 30 years these compressors require only 2.5 hours of preventive maintenance per year, including overhaul.
Low lifecycle cost – GAR 5-37 compressors are characterized by an extremely low lifecycle cost; a result of the high reliability and the long service intervals.
Compact and low weight – The GAR 5-37 design is extremely compact as a result of the integrated fan concept. The fan is mounted on the drive motor shaft, eliminating separate cooling systems etc. A GAR compressor therefore needs little space for installation. The use of aluminum reduces the weight as much as possible.
The Full Feature concept with integrated filters, unique SDR membrane dryers and aluminum air receivers will give you one single source to supply your system with clean dry air, without lost of energy due to high pressure drops and high purge air flows, compared to separate installations.
