Locomotive Compressors

Product catalog summary

Introduction
Gardner Denver has been manufacturing air compressors and compressor-exhausters for diesel-electric locomotives since 1935. These compressors are essential for operating air or vacuum braking systems and other locomotive accessories. The company offers a range of models, including 3, 4, and 6-cylinder versions, with both air-cooled and water-cooled options available.

Evolution and Design
Initially, Gardner Denver's compressors were water-cooled, but air-cooled models were introduced in the 1940s for freight locomotives. The 1950s saw a return to water-cooled designs due to higher horsepower engines. Today, Gardner Denver provides both cooling options and custom designs to meet specific locomotive needs. The compressors are engineered for easy maintenance, with accessible valves and a larger oil capacity to extend service intervals.

Performance and Reliability
These compressors are designed to withstand harsh environments, including tropical heat, desert sandstorms, monsoons, and arctic cold. Gardner Denver emphasizes reliability, serviceability, and efficiency, incorporating the latest technology and materials in their designs.

Key Features

Choice of air or water-cooled models, with water-cooled versions offering maximum heat dissipation.
Two-stage models include an intercooler.
Optimized pistons, rings, and cylinders for oil control and reduced oil carryover.
Rifle drilled connecting rods for lubrication at low speeds.
Ductile iron crankshaft with large tapered roller bearings for durability.
Full flow, spin-on oil filter for improved reliability.
Large oil capacity crankcase for prolonged oil life.
Positive displacement oil pump for pressurized lubrication.
Low lift valves for enhanced efficiency at high speeds.

Model Specifications
Compressor Models: The document lists various models such as WLV, WLU, WLA, WLN, WLT, and WLG, detailing their cylinder numbers, bore, stroke, cooling type, speeds, and other specifications.

Locomotive Compressor Evolution Gardner Denver has been building air compressors and compressor-exhausters for diesel-electric locomotives since 1935. Locomotive compressors perform the critical function of operating the air or vacuum braking systems and other accessories in the locomotive. Gardner Denver currently offers a complete line of locomotive air compressors and compressor-exhausters that includes 3 cylinder, 4 cylinder, and 6 cylinder models. Downtime is costly and the locomotive compressors were designed with ease of service in mind. The design and location of the valves is critical...

Locomotive Compressor Features 1. Choice of air or water cooled compressors. Water cooled models have cylinders and valve pockets fully jacketed for maximum heat dissipation. 2. All two-stage models come equipped with an intercooler. 3. Pistons, rings and cylinders are designed for optimum oil control. Cylinders are manufactured to gauge quality roundness, with tolerances measured in millionths of an inch. Exclusive Gardner Denver piston and piston ring design significantly reduces oil carry over into the air stream. 4. Rifle drilled connecting rods provide pressurized lubrication to the wrist...
