DESCRIPTION |
Product description:
This 30″ cotton string wound cartridge, made from food-grade bleached cotton, meets FDA-compliance requirements, making it suitable for Japanese food and beverage plants. The wound cotton provides real depth filtration to capture particles while preserving flow. The 10 μm rating protects downstream RO membranes, activated carbon, and polishing filters. Supplied in bulk by a manufacturer experienced in OEM operations, it can be customised in diameter, core type, and micron rating. The long length significantly reduces downtime due to filter changeout in high‑volume production lines.
Application Areas:
Beverage production water pretreatment in Japanese factories
Process water filtration in food manufacturing
Prefiltration ahead of RO systems in beverage plants
OEM filter supply to food equipment manufacturers
Reuse water systems in food processing
Features:
FDA‑compliant cotton ensures safe contact for food and beverage applications.
Depth-wound cotton structure enhances dirt retention.
Long 30″ format decreases change‑out frequency and labor cost.
OEM flexibility supports private label and customization by filter suppliers.
Durable cotton yarn handles moderate chemical and temperature stress.
