The Black Diamond 5 HP 80 Gallon Industrial Stationary Air Compressor is a heavy-duty machine built to maximize performance. It features a stable cast-iron cylinder body with durable Swedish stainless-steel flex leaf reed valves, and an integrated control panel to monitor all the gauges and valves from one location. The patented 2-stage pump in this air compressor is built from cast-iron to provide 175 PSI of air, and the Thermal Overload Protection system prevents harm to the motor from voltage fluctuations. Its vertical design also minimizes storage space and provides a ground stable base at all times.
