Key Features & Benefits

This compressor’s job is pretty straightforward – it takes in air and squeezes it, building up pressure. It’s basically an air pump. This specific one is a 318cc unit, which refers to how much air it moves per cycle – bigger number generally means it can keep up with demand a little better. The “single cylinder” part means it has one piston doing the pumping, and “flange mount” tells you how it attaches to the vehicle – it bolts right onto a mounting flange, making installation easier. This compressor is a key part of your vehicle’s air brake system, most often found on larger trucks, buses, and sometimes RVs. It provides the compressed air needed to operate the brakes, of course, but also for other air – powered features like the horn, suspension system, and even certain transmission functions. It’s the heart of the whole system, really.

Symptoms, Risks & Replacements

Without a functioning compressor, your air brakes won't work. Simple as that. They’re a safety critical item. A failing compressor might mean your brakes slowly lose power, or become unreliable. You'll notice if it’s starting to go, typically through longer brake engagement times, or the brakes feeling spongy. Also, you might hear the compressor running more often than usual as it struggles to keep up. If it fails completely, you lose braking power, which is, well, not good. You can find a replacement like this one easily enough – we stock a lot of air brake parts, and places like Fixparts Online are also good resources. Getting it sorted quickly is important for safety.
