Wabco 9125220020 Scania 636ccm Air Compressor

Description

The Wabco 9125220020 is a high-performance air compressor designed for Scania vehicles. This compressor is a key component of the vehicle's air brake system, providing compressed air for braking, suspension, and other pneumatic functions. It’s a twin-cylinder device with a swept volume of 636 cm3 and a calculated volume of 17.47. Its dimensions are 160 x 329 x 331 mm. The compressor features water cooling, lubrication supplied from the engine, and operates at 3000 (1/min). With a maximum operating pressure of 14.0 bar and flange mounting, this compressor ensures reliable and efficient air delivery, contributing to enhanced braking performance and overall vehicle safety. It’s a direct OE specification replacement.

Key Features & Benefits

Basically, this thing takes in air and squeezes it, builds up pressure, then stores it in the air tanks. It’s a pump, plain and simple. It’s driven by the engine via a belt, so when the engine’s running, this compressor is working. It doesn't just run constantly though, there’s a pressure switch that kicks it on and off as needed to keep the tanks filled. This compressor is absolutely vital for everything that relies on air brakes and air systems in your Scania. That includes the service brakes – the ones you use to actually stop the truck – the trailer brakes, the parking brake, even things like the air suspension if you’ve got it. It’s the heart of the entire air brake system. You'll notice if it starts to go because things will take longer to build pressure, and you might get warning lights on your dash.

Symptoms, Risks & Replacements

Without a functioning air compressor, you have no reliable brakes. It’s a safety thing, first and foremost. If the compressor can’t maintain pressure, your braking power gets weaker and weaker, and that’s obviously dangerous. It’s like a shield protecting you and everyone else on the road. It also affects other systems that rely on air, so you might find things like your suspension dropping or warning buzzers going off. A failing compressor isn’t something you want to ignore.
