Patented Originality.

Pfannenberg Filterfan 4.0™ are the result of 60 year's experience and continuous development. No fewer than 11 patented features ensure our leading position in the market. As part of the Pfannenberg εCOOL product line, our Filterfans® meet the increased demands of the industry in several areas:

  • Energy efficiency
  • Environment friendliness
  • Service friendliness.
  1. 1

    Reduced energy consumption

    More air, less power consumption.

  2. 2

    IP 54 protection

    Closed frame prevents unfiltered air from penetrating.

  3. 3

    Patented 4-corner fastening system

    for tool-less installation within seconds.

  4. 4

    Unrivalled airflow even at IP 55

    via patented fluted filter mat.

  5. 5

    Service time is up to 300 % longer

    This saves time and money.

  6. 6

    Neutral design without colour irritations

    Perfect harmony of colours with modern machines and equipment.

  7. 7

    Airflow optimised fins and rotor blades

    guarantee maximal airflow with minimal energy consumption.

  8. 8

    Efficiency

    Filterfans 4.0™ can be equipped with an optional thermostat – only when cooling is actually necessary.

  9. 9

    Easy integration in existing applications

    since most of the housing cut-out comply with the Pfannenberg standard.

  10. 10

    Easy and fast maintenance

    The click mechanism of the cover enables a filter mat replacement in seconds.

  11. 11

    Filterfans 4.0™ comply with national and international standards

    e.  g. TÜV, NEMA, cURus, EAC, CSA, CE.

Designed to deliver maximum airflow using minimal energy.

When developing the Pfannenberg Filterfan 4.0™, our engineers worked to make sure that minimal energy was used to produce maximum airflow. For this purpose we carried out extensive studies to measure and optimise the airflow characteristics of the rotor blades and fins in the housing covers. After more than 1,000 tests in our own climate chambers, the design was ready for market launch. In addition to maximum airflow with minimal energy usage, further improvements were achieved. The fins in the front cover have been specially designed to pre-filter the air, reducing the amount of dust particles and water droplets that can reach the filter mat. Lastly the design aesthetic was considered to allow the Filterfans® to integrate professionally into the design of each application.

Superior protection against electromagnetic radiation.

In most cases, industrial control cabinets are made of sheet steel. As a result of this choice of material, the cabinet provides very good protection against electromagnetic radiation. This protection is compromised by the plastic Filterfan® and cut-outs in the cabinet, allowing for electromagnetic waves to enter and escape in both directions through the opening. EMC Filterfans® close this “hole” safely and effectively. The EMC variants of Pfannenberg Filterfan 4.0™ have a safe contact surface, without a beryllium-copper-seal. The contact is made simply via the edge of the Filterfan or exhaust filter cut-out. This eliminates the need to scrape off the the coating or adhere a similar aid such as copper tape. Ultimately reducing the need to elaborately modify the cut-out so that good contact is made.
