QMA Polypropylene Filter Series

“Absolute” Rated High Performance Pleated Polypropylene Filter Cartridge

 

This filter is manufactured with a multilayer, graded densityasymmetric melt blown polypropylene media. This unique structure allows for low initial pressure drop and high dirtholding capacity, and long high efficient service.

 

Filter Features–Benefits

  • Micron ratings from 0.20 to 10 μm– Broad application rang

  • Meets USP 24 Class VI biological test for plastics

  • “Absolute” Efficiency – Rated at 99.98% (Beta 5000)

  • Graded pore density – Multilayer, graded density media – asymmetric pores for high dirt holding capacity

  • High surface area – High flow rate, and long on-line service – Minimize maintenance cost

  • Fixed Pore construction – Eliminates dirt unloading at maximum differential pressure

  • Polypropylene Construction – Inert to many process fluids

  • Various Gasket/O-ring materials – Compatible with many fluids

  • Heavy duty molded cage – High structural strength

The micron ratings shown at various efficiency and beta ratio value levels were determined hrough laboratory testing, and can be used as a guide for selecting cartridges and estimating their performance.

 

Under actual field conditions, results may vary somewhat from the values shown due to the variability of filtration parameters. Testing was conducted using the single-pass test method, water at 3 gpm/10” cartridge. Contaminants included latex beads, coarse and fine test dust. Removal efficiencies were determined using dual laser source particle counters.
