Introduction

The Cummins AF4979 Air Dryer is a component designed for use in commercial trucks, specifically within the air brake system. Its purpose is to remove moisture and contaminants from the compressed air that operates the truck’s brakes, ensuring reliable and efficient braking performance.

Basic Concepts of Air Dryers

Air dryers function by processing the compressed air produced by a truck’s air compressor. This air, which is used to actuate the brakes, often contains moisture and impurities that can lead to brake system malfunctions if not removed. Air dryers work by cooling the compressed air, causing moisture to condense and be separated from the air stream, thereby delivering cleaner, drier air to the brake system ¹.

Purpose and Functionality

This Cummins part is engineered to enhance the operation of a truck’s air brake system by ensuring the air supplied to the brakes is free from moisture and contaminants. This contributes to more consistent brake performance, reduces the risk of brake fade, and helps maintain the integrity of the brake system components over time ².
