The industrial screw type air compressor uses a screw air end driven by an electric motor to produce compressed air for a fixed air system. Intake air passes through filtration and control components before entering the compression section. After compression, the air moves through oil-gas separation and cooling before reaching the discharge connection. The DLM package combines the motor, compressor, separation system, cooler, controls, sensors, valves, and piping within one stationary machine. Direct transmission connects the motor and compressor drive path, keeping the mechanical arrangement relatively simple while supporting continuous high-volume compressed-air production at the stated operating pressure. The industrial screw type air compressor combines these features in one practical product.
