🔍 Key Concepts

• Air compressor unloading system function during startup and shutdown • Difference between mechanical load (compression load) and frictional load in machinery • What happens to motor starting current and torque if the compressor starts under full pressure

💭 Think About

• Think about what makes it difficult for an electric motor to start a compressor that is already pressurizing air. What condition would make starting easier on the motor? • When an unloader is active, is the compressor actually compressing air against pressure, or is it spinning more freely? How does that affect load? • Which of the options describe something that happens specifically at starting, and which describe conditions that are more related to normal running or shutdown?

✅ Before You Answer

• Identify which choice clearly describes reducing the compression (pressure) load on startup. • Eliminate any options that focus on intercooler temperature or valve seating, unless they directly relate to starting load. • Check which option matches the idea that the compressor is allowed to run with minimal resistance until it comes up to speed.
