Process Filter Liquids

Process filter Liquids

Many industrial companies require different types of process and service water for their production and manufacturing processes. These include, for example, water for cooling purposes, washing and flushing water, seal water for rotary seals, service water to prepare chemical solutions etc.

Expert pre-filtration prevents subsequent expense:

  • Improved service lives of fine filters and membranes downstream
  • Lower maintenance costs as a result of longer service intervals
  • Lower energy consumption
  • Increased process reliability
  • Reduced operating costs
  • Guaranteed quality

Automat. back-flushing filters AutoFilt®

Automatic back-flushing / self-cleaning filters extend service life and maintenance intervals in process technology

Self-cleaning back-flushing filters, type AutoFilt® by HYDAC are automatic filters for industry and technology. They ensure the cleanliness of water, coolants and lubricants as well as lower viscosity fluids. The AutoFilt® filter range is very versatile and diverse and ideally suited for retrofitting in existing plants.
