AccuFlow

AccuFlow cartridge is a precision filter product that combines the benefit of both a prefilter and final filter in one device to provide reliable and consistentperformance. The pleated filter medium is Accupor membrane, i.e., modified polyethersulfone hydrophilic membrane specifically developed by AF for many filtration applications. 

This cartridge is designed for long service and can be used for final filtration when absolute particle removal is necessary, or prefiltration where highly fine particle removal is desired to protect the final filter.

During the manufacturing process, each AccuFlow cartridge is flushed with proper solvents under controlled conditions to provide cleanliness, and integrity tested to assure product quality.

AccuFlow cartridge is compatible with autoclave and in-line steam sterilization, as well as chemical sanitization methods.

Performance Advantages

• Constructed of only two materials, i.e., modified polyethersulfone and polypropylene with no adhesives to ensure lower extractables
• All components meet USP Class VI-121°C Plastics Tests for biosafety, and are listed as being acceptable for food contact applications according to the Code of Federal Regulation, Title 21
• Provides high throughputs to minimize filter change-outs during batch processing
• Enhanced porosity of Accupor membrane as a filter medium in the cartridge results in low differential pressures and extended filter life
• Offers great resistance to severe sanitizing agents such as hot water, concentrated hydrogen peroxides, and active chloride compounds
• Available in a variety of configurations allowing easy installation in common-used filtration system
• 100% integrity tested during manufacturing to assure product reliability and quality
