LOFPLEAT-HP

Summary

Product Identification

The LOFPLEAT™HP Series is an absolute rated, high performance pleated polypropylene filter cartridge. This filter is constructed with a large surface area, melt blown polypropylene media designed for high dirt holding capacity with low initial pressure drop.

Features and Benefits:

• Fits a broad range of applications with 0.2 to 20 micron retention.
• Acceptable for food and beverage applications.
• Meets USP Class VI biological tests for plastics.
• Beta rating of 5000, 99.98% efficiency.
• High flow and long life for minimum maintenance.
• Eliminates dirt unloading at high differential pressure due to fixed pore structure.
• Heavy-duty molded cage for high structural strength.

• Filter Removal Efficiency:

  • Beta Ratio 5000: 99.98% efficiency
  • Beta Ratio 100: 99% efficiency
  • Beta Ratio 50: 98% efficiency

  The micron ratings shown at various efficiency and beta ratio value levels are:

  Beta Ratio 5000	Beta Ratio 100	Beta Ratio 50
  0.2 µm	0.10 µm	0.05 µm
  0.45 µm	0.30 µm	0.20 µm
  1.0 µm	0.60 µm	0.30 µm
  2.5 µm	2.0 µm	1.5 µm
  5.0 µm	4.0 µm	3.0 µm
  10.0 µm	8.0 µm	7.0 µm
  20.0 µm	17.0 µm	15.0 µm

  Note: Beta Ratio = Upstream particle counts / Downstream particle counts. Testing was conducted using the single-pass test method, water at 2.5 gpm/10" cartridge. Contaminants included latex beads, coarse and fine test dust. Removal efficiencies were determined using dual laser source particle counters.

• Flow Rate (70°F/21°C per 10" cartridge): A graph illustrates differential pressure vs. flow rate for different micron ratings. The flow rate ranges from 0 to 10 USGPM (0 to 37.9 LPM). Differential pressure ranges from 0 to 0.14 Bar (0 to 2 PSI). For liquids other than water, multiply pressure drop by fluid viscosity in centipoise. See the official PDF for exact tabulated values.

• Sanitization:

  • Hot water at 176°F (80°C) at 5 psid (0.35 bar) for 30 min.
