Wabco 911504506R Compressor

Description

This Wabco 911504506R compressor is a vital component within air brake systems, responsible for delivering compressed air to operate the brakes in commercial vehicles. It is used in heavy-duty trucks, buses, and other vehicles requiring robust air brake performance. This twin cylinder compressor features water cooling and is designed for flange mounting, ensuring reliable operation at a maximum operating pressure of 12.5 bar and an operating speed of 3000 (1/min). Its 75mm piston diameter and 26mm piston stroke contribute to a swept volume of 442 cm3 and a calculated volume of 11.42. The compressor is lubricated via the engine's lubrication system and conforms to OE specifications, delivering a highly efficient and durable braking solution. Dimensions are 145 x 250 x 315 mm.

Key Features & Benefits

This thing basically takes engine power and turns it into compressed air. It’s a pump, really. It draws in air, squeezes it down into a smaller space, and then stores it at high pressure. It also includes an unloader valve which periodically releases some of that pressure – think of it like letting a little air out of a tire to prevent it from overinflating. It’s constantly working when the engine is running, maintaining the right air pressure in your system. It's the heart of your air brake system. All those air brakes – the ones that stop your vehicle – rely on the pressure this compressor builds. That pressure is what pushes the air into the brake chambers, activating the brakes. It also powers other air – operated components, like the horn or sometimes even auxiliary suspension systems. Without it, you just wouldn't be able to safely and reliably stop.

Symptoms, Risks & Replacements

It’s critically important, honestly. The brakes are, obviously, the most vital safety system on any vehicle, but especially on something relying on air brakes. You’ll notice if this compressor is failing. You might experience longer braking distances, the brakes might feel spongy, or you’ll start seeing warning lights come on. A failing compressor means the air pressure drops, and that directly affects your ability to stop. Ignoring it isn’t an option. We carry a good selection of these – you can even find a lot of options over at Fixparts Online if you want to browse. Replacing a worn compressor is a lot cheaper – and certainly safer – than dealing with a brake failure.
