BOSS 4040 SG 40kw Generator/40 CFM Package

The BOSS 4040 SG is a purpose-built engine-driven package combining a 40kW generator and a 40 CFM rotary screw air compressor in a single integrated system. Designed for heavy-duty service trucks where both substantial power generation and continuous compressed air are required simultaneously — eliminating the need for two separate systems. The 4040 SG delivers both from one engine-driven unit, reducing maintenance complexity and total system weight.

This generator can be used for prime or stand by power and can be wired 3 phase or 1 phase at a frequency of 60 hertz. Voltage can be 120/240 1-PH or 208 to 240 and 416 to 480 volt 3-PH.
