How much does the primary reducer reduce the air pressure from and to?

The primary reducer in the Scott Air-Pak X3 Self-Contained Breathing Apparatus is designed to reduce the high-pressure air from a full cylinder to a lower, usable pressure for breathing. The correct reduction range is from 5500 psi to approximately 85-110 psi. This reduction is crucial as it allows the breathing apparatus to deliver air at a pressure that is safe and manageable for the user while still providing an adequate supply for their breathing needs.

This setup is essential for ensuring that firefighters and other users of the SCBA can operate effectively in hazardous environments without the risk of overwhelming pressure. Proper pressure regulation not only improves safety but also enhances performance and efficiency in the field when the device is in use. The specified range of 85-110 psi is ideal for maintaining consistent airflow and ensuring the SCBA performs effectively under stress.
