Progaf filter bag

Summary

Product identification

PROGAF filter bags offer high-performance absolute filtration with a progressive density depth filtration design, utilizing up to 12 layers of media. They feature 100% welded construction and a patented SENTINEL sealing ring. The bags are constructed from 100% polypropylene, providing pure, silicone-free materials.

• Construction: 100% welded
• Sealing: Patented SENTINEL plastic step-ring, pressure-activated sealing lip
• Media: Progressive density melt-blown polypropylene, up to 12 layers
• Material: 100% polypropylene
• Bottom Shape: Round
• Available Efficiency Codes: 50, 51, 55, 57

Operating limits

PROGAF filter bags are designed for bypass-free performance across all ranges of pressure, temperature, and micron rating.

• Filtration Efficiency: Up to +99.98%
• Clean Differential Pressure (∆P) for Size 02 @ 10 m³/h (water at ambient conditions):
  • PGF 50: 0.25 bar
  • PGF 51: 0.17 bar
  • PGF 55: 0.06 bar
  • PGF 57: 0.02 bar

PROGAF filters demonstrate superior dirt-holding capacity and lower average operating differential pressure compared to various cartridge and competitive bag filters. See the official PDF for exact tabulated values and graphical comparisons.

Feed water

PROGAF filter bags are fabricated from hydrophobic polypropylene media. Prior to installation in aqueous solutions, the bags must be pre-wetted by immersing them for a few minutes in a wetting solution compatible with the process fluid.

Applications

All materials used in PROGAF Filter Bags, including the multilayer melt-blown polypropylene media, are FDA/EC listed for food contact applications.

Typical applications include:

• Chemical and Pharmaceutical Industries (e.g., activated carbon removal, catalyst recovery, gel removal)
• Water Filtration (PROGAF 51 demonstrated a log 3.5 reduction of impurities)
• Micro-Electronics (e.g., chemical filtration, membrane prefiltration to reduce SDI values)
• Food, Ink, and Paint Industries
