Mega Flow

Product catalog summary

Product Specifications
Filtrafine Mega-Flow Series High Flow Filter Cartridges are designed for high purity water filtration and LCD/TFT wet processing applications. They feature a variety of filter media including High Flow Meltblown polypropylene (MEP), Highly Asymmetric PES membrane (MES), and Expanded PTFE membrane (MEF). The hardware is constructed from high purity polypropylene, ensuring chemical compatibility, and the sealing is achieved through thermal bonding. Gaskets and O-rings are available in materials such as Silicone, EPDM, Buna-N, and Teflon Encapsulated Viton.

Performance Specifications
The cartridges have a nominal outside diameter of 3.2 inches and are available in lengths of 10 inches. They offer a wide range of removal ratings, with retention ratings for MEP ranging from 0.25 to 10µm, and for MES and MEF from 0.1 to 0.45µm. The maximum operating temperature is 168°F (75°C), and the recommended change-out differential pressure is 35 psid (2.4 bar).

Key Features
The cartridges are compact, offering long on-stream life and reducing equipment downtime and maintenance costs. Each filter element is stamped with pore size, lot, and serial number for traceability. They are 100% flushed with 18 Megaohm-cm DI water for PES and PTFE media and are manufactured in a Class 1,000 clean room environment under an ISO 9001 certified quality system.

Ordering Information
Cartridges are available with different end configurations and materials for O-rings/gaskets. Flow rates are specified per 10-inch cartridge, and for liquids other than water, the differential pressure should be multiplied by the fluid viscosity in centipoises.

Graphical Data
The document includes graphs showing the relationship between liquid flow rates and initial differential pressure for different filter media (MEP, MES, MEF) at 20°C. These graphs help in understanding the pressure drop across the filter at various flow rates.
