Wabco 912512033R Compressor

Description

The Wabco 912512033R is an air compressor crucial for the operation of air brake systems, commonly found in commercial vehicles and heavy machinery. This twin cylinder compressor supplies compressed air to activate the brakes, ensuring reliable stopping power. It features water cooling, lubrication supplied from the engine, and is designed for flange mounting. The compressor has a calculated volume of 20.68, a swept volume of 636 cm3, and operates at 3000 (1/min) with a maximum operating pressure of 14.0 bar. Its dimensions are 341 x 326 x 186 mm. This compressor is built to OE specification, providing a durable and effective solution for demanding applications and ensuring consistent performance across a wide temperature range of -40°C to +105°C.

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.
