Automatic filter F480 (DN400-1800)
Automatic water filter F480
The self-cleaning automatic filter F480 is pneumatically operated and is used for the separation of solids in various media such as sea, river or process water. The filter ensures reliable and continuous filtration in various applications such as cooling water or water treatment plants.
✅ Typical application areas: energy sector, food industry, water industry, automotive industry
Description of filter function
- In normal filtration, particles accumulate from top to bottom on the inside of the screen.
- Cleaning starts automatically according to a time cycle or after a high pressure difference signal.
- During the pre-flushing phase, the flushing valve opens and larger particles are flushed out.
- 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.
- The released particles are flushed out of the filter by the flushing outlet. Finally, the flushing valve is closed.
- During the entire cleaning cycle, there is no interruption in filtration.
