hydro4

Extend the useful lifetime of the downstream high-performance filters

hydro4 filter cells have excellent coalescing properties and are ideally suited for applications with constant water spray or fogging.

Applications

hydro4 filter cells are used for intake air filtration of:

  • gas turbines in power generation and in the oil and gas industry

  • compressors, diesel and gas engines

Features

  • The filter design offers excellent coalescer and filtration performance.

  • Specially designed for use in limited installtion space.  

  • hydro4 filters are fully-potted resulting in a leak-free construction.

  • The entire filter element is metal-free and thus non-corroding and fully incinerable.

  • Thanks to coalescing properties ideally suited for applications where filters are exposed to constant waterspray or fogging.

  • Protection of the downstream high-performance filter stage against water droplets, extends thus their useful lifetime.

  • The Freudenberg "clip-on system" allows close coupling of the hydro4 554x554x96 variant to either the intermediate or the final filter without any structural modifications.
