automatic filter F451
The self-cleaning Automatic Filter F451 is pneumatically 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 standardized design and the use of cast housings the F451 sets a new benchmark when it comes to technical and economic efficiency.
SETTING A NEW BENCHMARK!
Reliable filtration by using the Bernoulli principle
OPTIMIZED DESIGN
The new F451 automatic filter series utilizes standardized cast housings and impresses with a significantly more compact design. Although the F451 is standardized, it can be easily adapted to specific application requirements. The F451 covers a broad range of materials like austenitic stainless steel (1.4581 / 316SS / SA-351), super austenitic stainless steel (1.4557 / SA-351) and ductile cast iron (GGG-40). All F451 filters can be designed according to PED, EN13445 or ASME VIII Div.1.
GRADE OF FILTRATION
The F451 ensures the safe protection of our customer’s applications with a consistently high filtration quality down to 100 μm. The proven Bernoulli technology warrants continuous and effective filtration even at low operating pressures starting from only 0.7 bar.

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
PRE-FLUSHING
CLEANING
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.
