The Wabco 4327020010 Exhaust Filter is a critical component within air brake systems, designed to remove contaminants and ensure clean air supply for optimal braking performance. It is commonly used in heavy-duty vehicles and trailers. This filter maintains system efficiency by preventing abrasive particles from entering sensitive brake components, contributing to extended service life and consistent stopping power. It measures 20 x 22 x 20 mm and features M16 x 1.5 port threads. It is manufactured to OE specification. This filter basically cleans the air that’s being exhausted from your air brake system. When the brakes are applied, or air is released, some dirty air, along with moisture and oil mist, gets pushed out. This filter traps all that gunk—dust, water, oil—before it gets released into the environment. It’s a multi – stage thing, often with a separating element to get the liquids out, and then a filter to catch the solid particles. Think of it as part of your whole air system. The air compressor makes the air, the dryer cleans it, and this filter cleans the exhaust air before it's vented. It's not directly involved in stopping the vehicle, but it keeps the system running cleanly. It’s a bit like having an oil filter for your engine, only for your air brakes. It prevents buildup and keeps everything functioning smoothly. It’s important for a couple of reasons. First, it’s about being environmentally responsible—you don’t want to be pumping oil mist into the air. But more importantly for you, a clogged exhaust filter can actually cause problems with your air brake system’s performance. It creates backpressure, which makes the system work harder. You’ll notice if it's really bad—things might feel sluggish, or you’ll hear different noises. It's a relatively inexpensive part to replace, and it can save you from bigger, more costly repairs down the road. You can find a good selection of these at places like Fixparts Online, and they’re usually pretty straightforward to swap out yourself if you’re comfortable with basic maintenance. If not, any good truck mechanic can handle it quickly. Reliable performance guaranteed: Exhaust Filter (MPN 4327020010) has a 12-month warranty!
