A wide range of equipment and instruments are installed in fixed circuits. HYDAC’s stationary filtration systems are designed to separate solid particles, with or without integrated fluid sensors.


  • Secondary flow filters for working filtration
  • Easy retrofitting in existing installations
  • Main flow filter discharge
  • Increased availability of facilities
  • Reduced lifecycle costs



Complementary Products




HYDAC offers a wide variety of complementary products for all types of hydraulic filters. There are three main groups of complementary equipment.


1. Filter Elements

The extensive product range provides different types of elements for numerous bypass filters. These elements are used to separate solid particles and water, available in the form of deep bed and surface filters.
