Fuchs filter Germany Fuchs model Fuchs price

The Fuchs filter consists of a housing, multi-element filter cartridges, a backwash mechanism, and a differential pressure controller. A partition plate inside the stainless steel filter housing divides the interior into upper and lower chambers. The upper chamber is equipped with multiple filter elements, which fully utilizes the filtration space and significantly reduces the filter volume. The lower chamber is installed with a backwash suction cup. During operation, water to be filtered enters through the inlet, flows through the filter screen, and exits into the user's required pipeline for process circulation. Particulate impurities in the water are retained inside the filter screen. With continuous circulation, the number of retained particles increases, causing the filtration speed to decrease. Meanwhile, contaminated water continues to enter from the inlet, causing the filter pores to become smaller. This creates a pressure difference between the inlet and outlet. When the differential pressure reaches the set value, the differential pressure transmitter sends an electrical signal to the controller. The controller activates the drive motor, which rotates the shaft via the transmission assembly. Simultaneously, the discharge port opens to expel contaminants. After the filter screen is cleaned, the pressure difference drops to the minimum value, and the system returns to the initial filtration state for normal operation.

Fuchs filter operating principle

The specially designed filter screen creates a jet effect inside the filter element, flushing any impurities away from the smooth inner wall. When the differential pressure between the filter inlet and outlet returns to normal or the timer setting expires, the entire process ensures continuous material flow with low backwash water consumption, achieving continuous and automated production. Due to the low concentration of production in the industry, low R&D capabilities for supporting high-end products, and low manufacturing technology levels in the stainless steel filter industry, the import-export trade deficit continues to expand. The coming years will be a period of rapid turbulence for the stainless steel filter industry. The direct consequence of this rapid turbulence is an expanding trend of polarization among brand camps. It is expected that the number of companies truly able to survive in the market in the coming years will be significantly lower. However, this rapid turbulence in the stainless steel filter industry will bring huge opportunities, and the result will make market operations more rational.

Fuchs filter design features

The stainless steel filter achieves automatic backwashing through its own detection and response functions, handling unstable water quality fluctuations without manual intervention. The stainless steel filter has few wearing parts, requires no consumables, has low operation and maintenance costs, and is simple to operate and manage. The stainless steel filter operates precisely and can flexibly adjust the backwash differential pressure time and time settings according to different water sources and filtration accuracies. During the backwashing process of the stainless steel filter, each filter screen (or group) performs backwashing sequentially; this ensures safe and efficient cleaning of the filter screen while other filter screens remain unaffected and continue filtering. The stainless steel filter uses a pneumatic discharge valve, resulting in short backwash duration and low backwash water consumption, making it environmentally friendly and economical. The stainless steel filter features a compact and reasonable structural design, small footprint, and flexible and convenient installation and movement.

Fuchs filter filtration speed

When solid particles in the suspension are large and uniform in size, the pores in the filter cake layer are relatively open, allowing the filtrate to pass through the filter cake layer at a higher speed. Applying coagulants to aggregate fine particles into larger clusters helps improve filtration speed. For suspensions where solid particles settle quickly, filters that feed material onto the upper part of the filter medium are used, aligning the filtration direction with gravity. Coarse particles settle first, reducing clogging of the filter medium and filter cake layer. Mixing coarser solid particles such as diatomaceous earth or expanded perlite into difficult-to-filter suspensions (such as colloids) can loosen the filter cake layer. When the filtrate viscosity is high, heating the suspension can reduce viscosity. These measures can all accelerate filtration speed. Long service life: The new plastic filter elements are robust, wear-resistant, corrosion-resistant, and rarely scale. Verified by years of industrial use, they show no wear after 6~12 years of use, do not age, and their filtration and backwash performance does not deteriorate with usage time. High quality, low maintenance: The products comply with corresponding quality standards. All products undergo simulated condition testing and trial operation before leaving the factory. No special tools are required, and there are very few parts. They are easy to use, requiring only regular inspections and almost no daily maintenance.
