It s actually venting the residual pressure from the compressor head so the motor doesn t have to work as hard on the next startup.

Before you dive into the unloader you should check the check valve between the pump and tank. While air is being pumped into the compressor tank through the port 1 the unloader valve is shut so the compressed air cannot flow along the air line attached to port 2 and escape to atmosphere. The check valve is one of the most common parts that fails on a compressor. If there is a reverse flow occurring the job of the check valve is to stop that flow.
