DuPont DOW Equivalent Performance with Cost Efficiency
LEFILTER's model is manufactured to be fully compatible with DuPont and DOW standard UF modules, allowing users to upgrade or replace their current units without modifying existing system configurations. It offers equivalent dimensions, membrane surface area (typically between 50–60 m²), and connection interfaces, ensuring seamless integration into your current ultrafiltration skid or housing.
Furthermore, it delivers comparable flow rates, filtration efficiency, and service life as global brands, but with improved cost-effectiveness. It reduces operational costs over time while ensuring strict compliance with cGMP and USP requirements.
Applications in Pharmaceutical Water Systems
The SFP/SFD2860 UF Membrane Module for Pharmaceutical is used in multiple critical pharmaceutical applications, such as:
-Pre-treatment for Reverse Osmosis systems, improving downstream membrane life and stability
-Final filtration stage for Purified Water (PW) and WFI systems
-Biotech fermentation media clarification, where removal of endotoxins and microorganisms is essential
-CIP and SIP (Clean-In-Place/Sterilize-In-Place) water recycling or reuse systems
Its reliable performance supports batch consistency, minimizes downtime, and ensures product safety — essential factors in pharma manufacturing.

FAQ
Q: Can the SFP/SFD2860 UF membrane module be directly replaced with DOW or DuPont models in my current UF system?
A: Yes, the SFP/SFD2860 is designed as a direct equivalent to DuPont and DOW UF modules. It matches standard module dimensions, connector types, and filtration parameters, ensuring hassle-free installation and system compatibility.
Q: How often should the UF membrane module be chemically cleaned in pharmaceutical applications?
A: Cleaning frequency depends on feed water quality and system design, but typically, chemical cleaning is recommended when the transmembrane pressure (TMP) increases by 15–20% from baseline. Most systems require cleaning every 1–3 months under standard pharmaceutical operating conditions.
