Two power sources in one
Generators are often needed on jobsites to provide electrical power for lighting or non-air or hydraulic-powered equipment, such as pumps, drills or welders. Compressor/generator systems eliminate the need for multiple power sources. Typically, a second V-belt pulley or gear is added to the compressor's engine drive shaft to power the generator.
"Combining these two important utilities into one package has many advantages and has resulted in increased popularity," says Chartters.
Before investing in such a package, evaluate both the compressor and generator for features to ensure optimum performance and value.
"When considering a compressor and generator combination, make sure the engine is powerful enough to operate the compressor and generator at full output," says Chartters. "Significantly reducing the output of either electrical power or compressed air during simultaneous operation is counterproductive. The control system must ensure that the engine delivers constant speed during generator operation to avoid frequency and voltage fluctuation, which could severely damage connected equipment such as pumps or drills."
