Key Features & Benefits

This compressor’s job is pretty straightforward – it takes in air and compresses it, then stores it under high pressure. It does this using two cylinders working together – that’s where the “twin” part comes from. It’s powered by the engine, usually through a belt, and it constantly cycles on and off to maintain the right air pressure in your system. It doesn’t just make air though, it also has an unloader valve that lets air escape when the system reaches its target pressure, preventing it from over – pressurizing. This is a key part of your air brake system, mainly if you’re driving a larger vehicle like a truck, bus, or maybe even some heavier – duty vans. That compressed air is what actually makes your brakes work – it powers the air cylinders that push on the brake shoes or calipers to stop the wheels. It also runs other air – powered components like your air horn, and sometimes things like suspension systems. Basically, anything that needs a burst of pressurized air relies on this compressor.

Symptoms, Risks & Replacements

It's critically important, plain and simple. Without it, your brakes won’t work, and that’s, well, pretty serious. You’ll notice if it’s failing because your air pressure gauge will start dropping while you’re driving, or it might take a long time for your brakes to engage. You’ll probably also hear the compressor running constantly, trying to keep up. If you start hearing a lot of noise, or the brakes feel spongy, get it checked immediately. A failing compressor can lead to complete brake failure, so it's not something you want to mess around with. We carry a good selection of these at Fixparts Online, and getting a new one installed by a professional is always the best bet.
