55B043 - Walter Bio-Circle Replacement Filter Bags - 200 Micron (6-Pack)

Technical Overview of the Walter 55B043 Filter Bag

The Walter 55B043 Filter Bag is a specialized consumable component engineered for the Bio-Circle series of industrial parts washers. This filtration unit is designed with a specific 200-micron porosity, serving as the primary mechanical separation stage within the closed-loop cleaning system. Its mesh size is calibrated to effectively capture medium-to-large particulate matter—including metal shavings, heavy grease agglomerations, and industrial sludge—while permitting the Bio-Circle cleaning liquid to circulate with minimal pressure drop. This balance ensures that the system maintains optimal flow rates for effective cleaning without straining the circulation pump.

Constructed from robust, chemical-resistant synthetic fibers, the 55B043 is built to withstand the continuous exposure to the bioremediating liquids and contaminants found in Bio-Circle L and Bio-Circle M environments. By physically removing solid waste from the fluid stream, the filter bag prevents the recirculation of abrasive particles onto the components being cleaned. This is critical for applications requiring high surface finish quality, as recirculated debris can cause micro-scratching or re-contamination of sensitive parts. Furthermore, the filter acts as a safeguard for the machine's internal hydraulic components, preventing nozzle blockages and reducing wear on the impeller assembly.

Maintenance of the filtration system is integral to the Bio-Circle's performance. A saturated filter can lead to reduced agitation and cleaning efficiency. The 55B043 is supplied in a pack of six, facilitating a consistent maintenance schedule for high-volume workshops. The 200-micron rating is particularly suitable for general maintenance and repair operations (MRO) where the soil load consists of mixed grease and metallic debris. Installation is tool-free and intuitive, ensuring a secure fit within the filter housing to prevent fluid bypass. Regular replacement of these bags significantly extends the usable life of the bath by reducing the total suspended solids (TSS) load, thereby optimizing the conditions for the bioremediation process.
