Correct method of wiring two screw air compressors

To connect two compressors in parallel, follow these steps: Make sure both compressors have the same voltage and phase. Install a check valve on each compressor’s discharge line to prevent backflow. Install a tee fitting on each compressor’s discharge line. Connect the two tee fittings with a pipe.. To connect two compressors in parallel, follow these steps: Make sure both compressors have the same voltage and phase. Install a check valve on each compressor’s discharge line to prevent backflow. Install a tee fitting on each compressor’s discharge line. Connect the two tee fittings with a pipe.. The Short Answer: The basic process involves setting up a single pressure switch system linking both compressors, using a check valve to prevent air backflow, and using suitable hoses or pipes. [pdf]
