Key Features & Benefits

This compressor's job is pretty straightforward – it takes the engine’s power and turns it into compressed air. It’s got two cylinders working together, which gives it a good amount of airflow, and the “636cc” tells you how much air it moves with each cycle. The “Flange Mount” just means how it attaches to the vehicle – it bolts directly onto a matching flange. It builds pressure and then holds it, ready to go when needed. Think of this as the heart of your air brake system. It feeds compressed air to everything – your brakes obviously, but also things like the air suspension if you have it, the horn, and any other air – powered accessories. It’s constantly running when the engine is on, maintaining the proper air pressure. It’s really the power source for stopping and controlling your vehicle.

Symptoms, Risks & Replacements

If this compressor starts to fail, you'll notice if your brakes feel weak or slow to respond, because you won’t be building enough pressure. It could also cause issues with your suspension sagging or the horn not working. It basically acts like a shield protecting your ability to safely operate the vehicle. A failing compressor is a serious safety issue. You can find these pretty easily, we stock a lot of air brake components, or places like Fixparts Online have them too. It’s one of those parts you really don’t want to put off replacing if it’s showing signs of wear.
