Filters by DANGO & DIENENTHAL: Reliable - All Over the World

For more than 75 years our area of expertise has been automatically cleanable filters, which reliably filter cooling water, process water and almost all kind of liquids 365 days a year, 7 days a week and 24 hours a day. Furthermore Separators, Sludge Dewatering Devices, Single- / Duplex Strainers and Bag Filters belong to our filter program.


 Products

  • Filterautomat DDF
    The Filterautomat is distinguished by an extremely robust design and an excellent backflushing performance. The complete filter area is cleaned by a rotating filter drum....

  • The fully automatic operated Filterautomat DDF eliminates solids contamination in pressurised cooling and process water systems by arresting contaminants across the whole surface of a specially constructed slotted strainer element in the filter drum where these retained contaminants then become part of the filtering function (100 % surface filtration).

    Periodic segmental backwashing cleans the strainer without interrupting the filtering process. Backwash is to atmosphere and a minimum pressure differential of 0,8 bar across the strainer is required.

    Design Data:

    flow rate 20 gpm to 46,200 gpm
    filter fineness ≥ 5 microns
    operating pressure 12 to 900 psi
    flange 2" to 40"
    automatic backwash: yes
    filter housing cast iron, steel, stainless steel

    Advantages:

    Inline construction
    Crushing of rough particles
    Minimum water loss for backwashing
    Insert of slotted-sieves and wire-cloth screens
    High backwash speed (up to 33 fps)
    100 % cleaning of the whole filter surface
    Constant charging of the whole filter surface
    Robust construction
    Easy to maintain by the inspection hole

  • JET Filter
    Inline filter without moving inner parts. The design allows for nearly all materials, flow rates, and mounting positions....

  • The fully automatic backwash filter type JET eliminate undesirable solid particles from cooling and service water supply systems and from other hydrostatic pressure systems. The impurities are separated from the liquid by retention in special slotted tube cartridges with axial slots (100% surface filtration).

    The JET Filter Type 2000 can be installed in the pipeline in any fitting position (horizontal or vertical). The filter has no moving parts.

    Design Data:

    flow rate 4 gpm to 110,000 gpm
    filter fineness ≥ 50 microns
    operating pressure 22 to 900 psi
    flange 2" to 120"
    manual/automatic backwash: yes
    filter housing steel, stainless steel, plastic,
    glas-fibre-reinforced plastic (GRP)

    Advantages:

    High backwash speed (up to 10 m/s)
    Any mounting position (horizontally / vertically)
    Simple installation (inline construction)
    Low wear (no movable parts in the filter)
    Low backwash water loss
    No differential pressure increase during the fi ltering process
    Wide range of materials
    Ready-made cabling
    Special design possible on customer’s request

  • JET Filter S
    More compact, ready-mounted backwash filter for low throughput rates. Universally applicable for practically all application areas...

  • The fully automatic backwash filter JET Filter S (JET-S) eliminate undesirable solid particles from cooling and service water supply systems and from other hydrostatic pressure systems. The impurities are separated from the liquid by retention in special slotted tube cartridges with axial slots (100% surface filtration).

    The JET Filter S can be installed in the pipeline in any fitting position (horizontal or vertical). The filter has no moving parts.

    Design Data:

    flow rate 4 gpm to 110 gpm
    filter fineness ≥ 50 microns
    operating pressure 22 to 145 psi
    threaded connection R 2"
    manual/automatic backwash: yes
    filter housing stainless steel, plastic

    Advantages:

    High backwash speed (up to 10m/s)
    Any mounting position (horizontally / vertically)
    Simple installation
    Low wear (no movable parts in the filter)
    Low backwash water loss
    No differential pressure increase during the filtering process
    Wide range of materials
    Fully wired, tested unit
    Constructive special solutions for specific customer requirements
