Knitted Mesh Engine Breathers
Knitted Mesh Engine Breathers | Compressed Engine Breather Pads
Knitted Mesh Engine Breathers are high-performance filtration components engineered to manage internal pressure and separate oil from venting air in internal combustion engine systems. They are manufactured from precision knitted wire mesh and are widely used in automotive, marine, and industrial applications where effective air/oil separation, low pressure loss, and emission control are critical.
Engine breathers play a crucial role in crankcase ventilation systems by allowing pressure equalization while capturing oil mist and preventing contaminant release to the environment, supporting engine longevity and regulatory compliance.
Advantages of Knitted Mesh Engine Breathers
- High Filtration Efficiency
Engine breathers remove up to 99% of oil droplets in the 3–10 micron size range, ensuring effective separation of oil mist from vented air and minimizing oil loss and emissions. - Minimal Pressure Drop
The knitted mesh structure creates a high free-volume ratio that allows maximum airflow with a very low pressure drop, typically less than 5 millibar, which helps maintain optimal engine breathing and performance. - Corrosion and Temperature Resistance
Standard elements are produced from high quality galvanised steel. For demanding environments, options include stainless steel and alternative alloy materials to enhance temperature tolerance and corrosion resistance. - Customisable Form Factors
Knitted mesh elements can be supplied in a variety of configurations — including die-compressed, layered, or spiral-wound formats — to match different breather housings and cavity geometries. - Ease of Installation and Maintenance
The breathable mesh is engineered for straightforward integration into existing breather housings or oil filler caps. Its simple structure facilitates replacement and reduces maintenance downtime.
