automatic filter F450

The self-cleaning Automatic Filter F450 (E) is pneumatically or electrically operated and used for the separation of solids in various different media like seawater, river water or process water. The Filter ensures reliable and continuous filtration in a variety of applications like cooling water cycles or water treatment plants. The filter can operate at very low pressures of only ≥ 0,7 bar and is characterized by an unmatched low pressure loss, a compact design and near maintenance-free operation. Due to the flexible combination of different design solutions and materials, the F450 can be easily adapted to the customer’s specific requirements.

THE PROVEN ALL-ROUNDER

Reliable filtration by using the Bernoulli principle

CUSTOMIZED DESIGNS
The F450 can be adopted to all customer requirements and offers a broad range of materials suitable for almost every application. The design allows flexible nozzle positions which ensures a simple integration into the piping. Furthermore, the F450 can be designed according to many national and international codes and regulations, among others, EN13455, ASME, AD2000, EAC and ATEX.

EFFICIENT CLEANING
The F450 ensures the safe protection of our customer’s applications with a consistently high filtration quality down to 150 μm. The proven Bernoulli technology warrants continuous and effective filtration even at low operating pressures starting from only 0.7 bar.

SMART CONTROL
Georg Schünemann offers a wide range of Control units. From stand control units up to customized control units specifically designed for the individual application. Based on the local requirements the LCP can be equipped with different communication interfaces like Modbus, Profibus or Ethernet. This enables a safe LCP to PLC communication and to ensures a convenient remote monitoring of the filter system.

FILTRATION CYCLE (BERNOULLI PRINZIPLE)

Bernoulli‘s principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure. Georg Schünemann has perfected the utilization of the Bernoulli principle for automatic filters over decades. The distinguishing feature of this filter is the flushing disc, which enables an efficient and contactless cleaning. The cleaning process is completely automatic and requires no manual intervention.

FILTRATION


During normal filtration, particles accumulate from top to bottom on the inside of the strainer.
Cleaning begins automatically according to a timed cycle, or after a high differential pressure signal.

PRE-FLUSHING

During the pre-flushing phase, the flushing valve opens and particularly larger particles are flushed out.

CLEANING



The flow velocity increases locally around the disc within the gap between the flushing disc and the strainer. Simultaneously the static pressure is reduced in accordance with the Bernoulli Principle and the direction of the flow is reversed which releases the particles from the surface of the strainer basket.

The released particles are flushed out from the filter via the flushing outlet. Finally, the flushing valve is closed.

The filtration will not be interrupted during the entire cleaning cycle.
