Filtro de pressão DF Filtro de pressão para fluxo reversivel de óleo DFF/DFFX até 2000 l/min, até 420 bar

TECHNICAL SPECIFICATIONS

FILTER HOUSING

Construction The filter housings are designed in accordance with international  regulations. They consist of a filter head and a screw-in filter bowl. DFF filters are suitable for flow in both directions. The Dp optimized filters DFFX are also suitable for flow in both directions and the filter ports are in L configuration. Standard equipment:

  • connection for a clogging indicator in filter head
  • drain screw with pressure relief (for size DF/DFF/DFFX 330 and above)
  • 1 or 2-piece filter bowl available as an option for DF/DFF/DFFX 280-660 and DF 2000
  • 2-piece filter bowl standard for size DF/DFF/DFFX 990 and above 1.2

FILTER ELEMENTS

HYDAC filter elements are validated and their quality is constantly monitored according to the following standards:

  • ISO 2941, ISO 2942, ISO 2943, ISO 3724, ISO 3968, ISO 11170, ISO 16889
