Key Features & Benefits

This compressor’s job is pretty straightforward – it takes the engine’s power and turns it into compressed air. It basically sucks in air, squeezes it down to a higher pressure, and then stores it in the air tank. It does this using two cylinders working together – that’s what the “Twin Cylinder” part means – and the 476cc tells you how much air it moves with each cycle. The "Flange Mount" just describes how it physically attaches to the vehicle. Now, that compressed air is what powers everything in your air brake system – your brakes, of course, but also things like the air suspension if you have it, and even the horn. It’s the heart of the whole system. The compressor continuously runs when the engine’s on, keeping that air tank filled and ready to go when you need it. Think of it like constantly refilling a bottle so you always have enough pressure for what you need.

Symptoms, Risks & Replacements

This is a critical component, honestly. If this compressor goes bad, the whole air brake system fails. You’ll notice if it’s failing because your air gauge will start to show lower pressure than usual, and you might hear the compressor working harder, or making unusual noises. You’ll definitely feel a difference in your brake performance – it’ll take longer to stop, and the brakes might not hold as well. It's something you really want to keep in good shape for safety. We carry these quite often at Fixparts Online, and have a good selection, but you can find them at most auto parts stores. It's one of those parts where it's much better to replace it before it leaves you stranded.
