Air System

What does the air system do?

The compressor produces compressed air. The air dryer helps remove moisture from that air. Air receivers store the compressed air so that it is available for the braking system and other connected systems.

Air springs use compressed air to support the truck and absorb movements while driving. They are part of the air suspension system.

The air filters in this category serve a different purpose. They filter the air drawn into the engine. The air filter housing holds the filter in place.

Why is the ventilation system important?

A truck with air brakes requires sufficient air pressure for the braking system to function properly. The air suspension also requires an adequate air supply.

An air leak, slow pressure buildup, or a truck that’s tilted to one side may indicate a malfunction. The cause varies depending on the system. Therefore, have a professional check which component is causing the problem first.

What should you look for when making your choice?

Check the original part number, often referred to as the OEM number. Also, compare the truck's make, model, and trim level.

When selecting an air heater, pay attention to its capacity, dimensions, mounting, and connections. When selecting an air dryer, also check the plugs and the design of the pressure control. When selecting an air bellows, compare the dimensions and mounting points.

Are you looking for an air filter or an air filter housing? Be sure to check the engine type and the shape of the filter. A part that looks like the old one won't always fit.

Applications in Maintenance and Repair

Have the compressed air system inspected for leaks, damaged pipes, and worn-out fittings. Also check the air dryer and the condition of the air receivers.

Follow the vehicle manufacturer's instructions for maintenance and replacement. Have the operation and air pressure checked after installation. For air filters, follow the engine's maintenance guidelines.
