Cotton on Tinned Steel String Wound Filter Cartridge

Flowrite Wound filter Cartridges are an improved, conventionally wound filter cartridge manufactured on state-of-the-art precision winding machines. Continuous length winding eliminates dead spots and bypass. The single strand, purpose-spun roving employs a strictly controlled material to produce a consistently high quality filter cartridge giving optimum flow and filtration performance.

Advanced manufacturing technology and strict in-house quality control, combined with a variety of wind patterns, ensures filtration that best fits the application to provide economical and consistent results time after time. For advice on specific applications contact Germ Africa
