Automatic filter F451 (DN32 - 300)

Automatic water filter F451

The new F451 range of automatic filters uses standardised cast housings and features a significantly more compact design. Although standardized, the F451 can be easily adapted to specific application requirements. The F451 covers a wide range of materials.

Benefits of the F451 filter

  • Automatic self-cleaning: self-cleaning technology allows continuous operation
  • Easy maintenance: maintenance requirements are minimal
  • High efficiency: the F451 offers a wide range of filter finenesses
  • Durable construction: the filter is made of corrosion-resistant materials
  • Flexible applications: Suitable for use in a variety of industries

✅ Typical applications: energy, food industry, water industry, automotive industry

Principle of filter function

Princip funkce filtru F451

  1. During filtration, dirt accumulates from top to bottom on the inside of the screen.
  2. Cleaning is done automatically by means of a time interval or when a high differential pressure is detected.
  3. During the pre-flushing phase, the flushing valve is opened and larger particles are flushed out.
  4. The flow velocity increases locally around the disc in the gap between the disc and the screen. At the same time, the static pressure is reduced according to Bernoulli's principle and the flow direction is reversed, releasing particles from the screen surface.
  5. The released particles are flushed out of the filter by the flushing outlet. Finally, the flushing valve is closed.
  6. There is no interruption of filtration during the entire cleaning cycle.
