Coalescer Elements are used in the 1. stage of filter water separators. Their main function is coalescing of small water droplets to big droplets. These big water droplets drop to the watersump of the filter water separator because they have higher density than fuel. Furthermore they holding back particles like sand, rust and other soiling.

Working principle

Droplets of oil, water and other liquids are captured by the microfibers inside the coalescer. These micron-sized fibers form a tortuous path to the airflow, forcing solid particles and liquid droplets to collide in inertia, diffuse intercept and direct intercept. Under the action of the filtration mechanism, it is captured by the ultrafine fibers, and the surface tension of the liquid causes the small droplets to coalesce into larger droplets, and the large droplets settle to the bottom of the container due to gravity.

The coalescing filter element mainly uses surface-treated glass fiber or polyester fiber as the coalescence medium, and the structure of the filter material is specially designed to make the filter medium have good coalescence performance. The filtration precision can reach 0.1μm.
