LOFPLEAT-HT

Summary

Product identification

The LOFPLEAT™HT Series filter cartridge is a High Temperature Micro Fiberglass Filter Cartridge. It offers disposable media with a high-efficiency Borosilicate Micro Fiberglass construction, featuring a greater surface area and high system flow rate.

Features and Benefits

• High temperature filtration capability of 230°F (110°C)
• Consistent pore size for high efficiency removal of debris
• Polyester hardware offers increased range over those of standard polypropylene
• High surface area for increased flow and dirt holding capacity
• Long service life provides low cost changeout benefits
• Maximum differential pressure dirt unloading eliminated by fixed pore construction
• Broad application range with micron retentions from 0.2 µm to 30 µm

  • 60 psid @ 200°F (4.1 bar @ 93°C)
  • 50 psid @ 230°F (3.4 bar @ 110°C)
• Recommended changeout pressure for disposal: 35 psid (2.4 bar)

Filter Removal Efficiency

The filter's removal efficiency is characterized by its Beta Ratio, defined as the ratio of upstream particle counts to downstream particle counts.

• Beta 10: 90% efficiency
• Beta 20: 95% efficiency
• Beta 100: 99% efficiency
• Beta 1000: 99.9% efficiency
• Beta 5000: 99.98% efficiency

Micron ratings at various Beta Ratio values are provided. See the official PDF for exact tabulated values. Testing was conducted using the single-pass test method with water at 2.5 gpm/10" cartridge, employing latex beads, coarse and fine test dust, and dual laser source particle counters.

Mechanical / hydraulic

A flow rate graph is provided showing Differential Pressure (Bar/PSI) versus Flow Rate (USGPM/LPM) for a 10" cartridge at 70°F (21°C). Separate curves are shown for micron ratings of 0.2 µm, 0.45 µm, 1 µm, 3 µm, 10 µm, and 30 µm. For liquids other than water, the pressure drop should be multiplied by the fluid viscosity in centipoise. See the official PDF for exact graph values.
