912510303R Wabco Compressor

Wabco 912510303R Compressor

Description

This Wabco compressor (MPN 912510303R) is a critical component of air brake systems, providing compressed air for the actuation of brakes in commercial vehicles. It's designed for flange mounting and utilizes lubrication supplied from the engine. This twin cylinder compressor features a calculated volume of 46.2 and a swept volume of 636 cm3, with dimensions of 500 x 330 x 280 mm. The water-cooled design and OE specification ensure reliable and consistent performance, while the crankshaft thread of M20 x 1.5 and various port threads (Ø 25 mm, M26 x 1.5, M10 x 1.0, Ø 4 mm, Ø 15.5 mm, M16 x 1.5) facilitate seamless integration into existing systems. Operating at 3000 (1/min) and a maximum pressure of 12.5 bar, this compressor offers robust air delivery for demanding applications.

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. Product information is provided for reference only.
