LOFPLEAT-HF-G

Summary

Product identification

LOFPLEAT™ HF-G High Flow Capacity Glasfiber Filter Cartridges are designed with pleated microglasfiber media. They offer high total surface area, allowing a single cartridge to replace several standard elements, leading to quicker and easier change-outs. The unique inside-out flow design contributes to higher debris holding capacity.

Features and Benefits

• Higher flow capacity reduces required number of cartridges
• Lower initial costs with smaller vessel
• Less labor required for changeouts
• Available with absolute rated media at 1 to 20 µm retention levels
• Inside-out flow for greater dirt holding capacity
• Capable of flow rates up to 1,892.5 l/min in a single 60” length
• Can be retrofitted in most competitive high-flow housings
• Thermally bonded construction

  • 3.4 bar @ 110°C (230°F @ 50 psid)
• Recommended changeout differential pressure: 2.4 bar (35 psid)

Filter Removal Efficiency

The cartridges provide the following removal efficiencies based on Beta Ratio:

• Beta 1000: 99.90% efficiency
• Beta 100: 99% efficiency
• Beta 10: 90% efficiency

Corresponding micron ratings for these Beta Ratios are:

• 1 µm: Beta 1000 (1), Beta 100 (0.6), Beta 10 (0.2)
• 2.5 µm: Beta 1000 (3), Beta 100 (2), Beta 10 (1.5)
• 4.5 µm: Beta 1000 (5), Beta 100 (4), Beta 10 (3)
• 10 µm: Beta 1000 (10), Beta 100 (8.5), Beta 10 (6.5)
• 20 µm: Beta 1000 (22), Beta 100 (19), Beta 10 (14)

Element Pressure Drop

A table providing Element Pressure Drop in mbar/m³/h and psid/gpm for various lengths and micron ratings is available. See the official PDF for exact tabulated values.
