Shopping for Air Suspension Compressor Dryer

Summary:

  • Also called “air ride suspensions,” air suspensions have many parts not found in their conventional counterparts. One of these parts is the air suspension compressor dryer.

  • The primary job of the dryer is to remove moisture from compressed air before the air goes to the reservoir. Most dryers achieve this by using a desiccant.

  • Many dryers also cool the pressurized air to remove as much water as possible.

  • The useful lifespan of an air suspension compression dryer often depends on the desiccant. Most dryer models are designed with replacement in mind, while it’s possible to replace saturated desiccant beads in other dryers.

  • Symptoms of a bad or failing air suspension compressor dryer include corrosion and rust. Other warning signs are an unevenly leveled suspension, issues with the compressor, rougher rides, lower ride level, and sagging.

  • A replacement air suspension compressor dryer can cost anywhere between $40 and $60.

Most suspension systems rely on metal springs to support the vehicle’s weight and control the body’s movements when driving over rough patches of road surface. Luxury vehicles take it to the next level with air suspensions that use air springs, which are rubber bellows filled with pressurized air.

Also called “air ride suspensions,” these suspensions have many parts not found in their conventional counterparts. There’s the air compressor, the air reservoir, and the air compressor dryer. Each part contributes to the air suspension’s overall performance, so it’s important to replace an air compressor dryer when it shows signs of wear or failure.

What Is an Air Suspension Compressor Dryer?

The air suspension compressor dryer sits between the air compressor and the air reservoir. Many air suspensions place the dryer on top of the compressor.

As its name implies, the primary job of the dryer is to remove moisture from compressed air before the air goes to the reservoir. Most dryers achieve this by using a desiccant made of silica or a similar substance that absorbs moisture.

The service life of a desiccant is set by its storage capacity. Once the material collects the maximum amount of water it can hold, the desiccant cannot absorb any more moisture from the pressurized air.

What Does an Air Suspension Compressor Dryer Do?

The primary purpose of the air suspension compressor driver is removing moisture from the air coming from the air compressor. Many dryers also cool the pressurized air to remove as much water as possible.

Removes Moisture From Compressed Air

The air pressure in the air spring determines how much weight the spring can support and the ride height at which it holds up the vehicle. The transmission control module constantly checks the pressure levels in each spring. When it detects the need to raise or lower the spring, it tweaks the performance of the air compressor accordingly.

Air usually contains moisture, the amount of which varies between regions and climates. When the air suspension compressor gets air from outside the vehicle, it also sucks in the water droplets suspended in the air.

While moisture doesn’t change the properties of the pressurized air, it can affect certain parts of the air suspension system.

Parts made of steel will eventually corrode due to the moisture, even if they’re protected by an anti-corrosion coating. Rusty moving parts will move slower and risk breaking down earlier.

Moisture can also degrade the seals that keep air from leaking out of the air suspension. If a seal springs a leak, the pressure will drop, causing the air spring to underperform.

This is where the air suspension compressor dryer comes in. It keeps the air flowing to the air reservoir and air springs as dry as possible, minimizing the risk of metal corrosion and seal degradation.

Cools Pressurized Air

To remove the maximum amount of moisture from the pressurized air, the air suspension compressor dryer can also lower the air temperature.

Cooler temperatures cause water vapor to condense into liquid droplets that are too heavy to remain afloat in the air.

The compressor heats the air during the process of pressurization. The heat turns water into vapor, and the compressed air cools quickly once it leaves the compressor.

Many dryers speed up this process so that the water vapor can condense while the air is still in the dryer. The resulting water droplets fall into the desiccant, leaving the much drier air to go to the air reservoir.

When Should You Replace the Air Suspension Compressor Dryer?

The useful lifespan of an air suspension compression dryer often depends on the desiccant. Once the desiccant hits its saturation point, it won’t absorb any more water from the air. That leaves the air suspension vulnerable to increasing amounts of moisture.

Most dryer models are designed with replacement in mind rather than servicing. Remove the old dryer and install a new assembly when the desiccant hits its saturation point.

Some air suspension compressor dryers make it possible to replace saturated desiccant beads with fresh ones. Some desiccants will visibly change color as a visual guide to their saturation level.

Check the vehicle manual and relevant resources to determine if the air suspension compressor dryer is replaceable or not. Also, look up the stock desiccant to find out if its beads helpfully change color once they get saturated with moisture.

If the air suspension compressor needs replacement, get a new dryer. Never mix a new compressor and saturated dryer because that increases the risk of the back pressure overloading the compressor.

Symptoms of a Bad or Failing Air Suspension Compressor Dryer

Check the entire air suspension regularly. Pay close attention to its metal parts for any signs of corrosion. Once the compressor dryer stops working, steel parts will quickly corrode or rust.

Once moisture accumulates in the air suspension, it can corrode metal moving parts and pressure seals, resulting in the suspension losing efficiency. Symptoms of this later stage include:

  • Uneven or incorrect leveling of the suspension

  • Problems with the air suspension compressor

  • Rougher ride as the suspension cannot dampen out the shocks of a bumpy ride

Inspect the vehicle’s ride level. A lower ride or visible sagging could stem from excessive moisture because of a bad air suspension compression dryer.

How Much Does an Air Suspension Compressor Dryer Cost?

A replacement air suspension compressor dryer can cost anywhere between $40 and $60. It is sold individually.

Picking the Right Air Suspension Compressor Dryer

Hunting for a replacement for an air suspension compressor dryer? The first step is to get the vehicle’s relevant technical data. Aside from the year, make, and model, look for important details about the air suspension itself.

Next, check the specifications of the old dryer. Jot down the assembly’s physical dimensions and the size of its port.  Determine the dryer’s connection type as well. Some dryers secure themselves to their mounting points with snap rings. Others rely on clips.

Once you’re armed with these crucial information, it’s time to look for a new air suspension compressor dryer. Always get a product that’s designed for the specific vehicle and manufactured by a trustworthy company. Compare the new dryer’s specifications with those of the old one to ensure compatibility.

It’s easy to find a replacement air suspension compressor dryer on our website. Entering the vehicle’s details into the filter bar will bring up guaranteed-fit parts from a wide selection of products.
