BOSS BA440 Piston Hydraulic Air Compressor
The BOSS BA440 is a compact, hydraulically driven piston air compressor designed for service trucks, utility vehicles, and other mobile applications requiring reliable intermittent compressed air. The aluminum, single-stage V4 reciprocating compressor provides up to 40 CFM at 100 PSI with a maximum operating pressure of 150 PSI.
The BA440 uses a direct-coupled hydraulic motor, eliminating drive belts and helping reduce routine maintenance. Its lightweight aluminum construction provides improved heat dissipation and corrosion resistance while keeping the unit compact for truck-mounted installations.
