Wabco 912512029R Compressor

Description

This Wabco 912512029R compressor is a critical component of air brake systems, used to supply compressed air for the activation of brakes in commercial vehicles. It’s a twin cylinder device utilizing lubrication supplied from the engine for enhanced durability. This compressor features a calculated volume of 22.4, water cooling, and is designed for flange mounting with an operating speed of 3000 (1/min). Key dimensions are 350 x 200 x 320 mm, with a swept volume of 636 cm3. The unit is engineered to OE specification, providing reliable and consistent performance for demanding applications. It features crankshaft thread M20 x 1.5, max operating pressure of 14.0 bar, and several port threads including Ø 34.9 mm, M26 x 1.5, M16 x 1.5 and M12 x 1.5.

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.
