efficiency 0.22 µm folded polypropylene (PP) cartridge designed for wine filtration. The pleated 5inch design provides a compact, surfacearea filter element that captures ultrafine particulates to improve clarity, protect downstream equipment, and reduce microbial load in smallscale and production winemaking processes. Key benefits Ultrafine 0.22 µm filtration: captures very fine particulates and reduces microbial contaminants that cause haze and spoilage, helping preserve wine quality before bottling. Pleated (folded) PP construction: increased surface area for higher dirtholding capacity and longer service life compared with nonpleated elements of the same size. Compact 5inch form factor: ideal for bench, portable, and inline systems where space is limited or where shortrun filtration stages are needed. Foodcompatible polypropylene material: chemically stable with common wine additives and cleaning agents, suitable for contact with wine under normal use conditions. Simple integration: designed for use as a filter cartridge in systems that accept 5inch folded PP cartridges, enabling straightforward replacement and maintenance. Key attributes Filtration rating: 0.22 micrometer (µm) Material: Folded (pleated) polypropylene (PP) Length: 5 inches (approximately 127 mm) Function: Fine particulate and microbiological reduction for wine filtration Form: Folded/pleated cartridge for increased surface area and capacity Typical applications and use cases Final polishing before bottling: Use the 0.22 µm folded PP cartridge as a polishing stage to improve visual clarity and reduce residual yeast and bacteria prior to filling and sealing. Smallscale winery and home winemaking: Compact size and efficiency make this cartridge well suited to bench filtration setups, mobile filtration carts, and shortrun production lines. Protect downstream membranes and equipment: Install upstream of sensitive membranes or metering pumps to reduce clogging and extend the life of more costly filtration stages. Practical notes for use Installation: Intended for systems designed to accept 5inch folded PP cartridges. Ensure proper sealing and flow direction as recommended by your filter housing manufacturer. Maintenance: the cartridge when flow rate declines significantly, when pressure differential reaches system limits, or after the recommended service interval from your process protocol. Cleaning and sanitization: Follow winerystandard cleaning and sanitization procedures compatible with polypropylene elements; avoid exposure to solvents or conditions that could damage PP. This 0.22 µm 5inch folded PP cartridge provides a reliable, spaceefficient solution for removing fine particulates and reducing microbial load in wine filtration applications, delivering improved clarity and protection for downstream equipment without compromising process simplicity.
