Motor: Provides power to drive the piston.
Cylinder and piston: Responsible for compressing the air. The piston reciprocates within the cylinder, compressing the incoming air.
Dryer: This is a crucial component. It contains a desiccant that absorbs moisture from the compressed air, preventing it from entering the air path and causing icing, rust, or corrosion, ensuring the proper functioning and longevity of the system.
Check valve: Ensures that high-pressure air can only flow from the pump to the airbag, preventing backflow of air from the airbag.
Pressure relief valve: Automatically releases excess air when system pressure is too high, protecting the system from damage.
