Our Wound Cotton Filter Cartridge OEM Custom 50 Micron 30 Inch 304SS End Caps is designed to deliver reliable depth filtration for a wide range of industrial and commercial applications. With over 20 years of manufacturing experience and annual export value of US$5-10 million, we focus on quality, customization, and durability. This cartridge combines high-purity cotton fibers, precise winding technology, and corrosion-resistant 304 stainless steel end caps, ensuring consistent performance and long service life.
Product Features & Benefits:
- High Dirt Holding Capacity: The wound cotton construction traps particles throughout the depth of the media, providing longer service intervals compared to surface filters.
- Precision Filtration: 50 micron nominal rating effectively removes sediment, sand, rust, and other suspended solids from water and process fluids.
- Rugged 304SS End Caps: Stainless steel end caps offer superior strength, corrosion resistance, and compatibility with high-pressure housings. They are reusable and easy to clean.
- Customizable Design: Available in OEM/ODM configurations – we can adjust length, micron rating, core material (PP or SS), end cap type (flat, open, or with gasket), and packaging to meet your specific requirements.
- Thermal & Chemical Resistance: Cotton media can withstand temperatures up to 52°C (125°F) and is compatible with many aqueous fluids, mild acids, and alkalis.
- 1-Year Warranty: Each cartridge is backed by a one-year warranty against defects in materials and workmanship.

FAQ:
-
What is the actual filtration efficiency of the 50 micron cartridge?
Our 50 micron wound cotton cartridges have a nominal rating, meaning they trap approximately 50-60% of particles at 50 microns, with higher efficiency for larger particles. For absolute filtration, we can customize to finer micron ratings upon request. -
Can I use this cartridge for hot water or aggressive chemicals?
The cotton media is recommended for water and mild chemicals at temperatures up to 52°C. For harsh chemicals or high temperatures, we offer alternative media such as polypropylene or glass fiber – please consult our sales team. -
How often should I replace the cartridge?
Replacement frequency depends on the solids load in your fluid. Typically, when the differential pressure reaches 1.0-1.5 bar (15-20 psi), it is time to change. The high dirt holding capacity of wound cotton often extends service life compared to pleated filters. -
Are the end caps removable or reusable?
The 304SS end caps are permanently attached during manufacturing to ensure leak-free performance. However, the stainless steel end caps can be cleaned and reused if you replace only the wound cotton core (custom design available). -
What core material options do you offer?
We offer standard polypropylene (PP) core and stainless steel (304SS) core. The PP core is economical and chemically resistant; the SS core provides higher strength and temperature tolerance. -
Do you provide OEM/private label service?
Yes, we are a dedicated OEM manufacturer. We can print your logo on the cartridge, customize packaging, and adjust specifications such as length, micron rating, and end cap type. Minimum order quantity may apply for custom branding. -
What is the lead time for this product?
For standard configurations, lead time is 7-15 days after order confirmation. For custom orders, it may be 15-25 days. We maintain a stock of popular sizes to expedite shipping. -
Do you offer free samples?
Yes, we provide free samples for qualification. You only need to pay for shipping. Please contact us with your requirements.
