Montz-Pak

Type A3 Wire Gauze Structured Packing

With the lowest pressure drop per theoretical stage of any mass transfer product, Montz-Pak type A3 wire gauze structured packing is optimized for applications with deep vacuum conditions.  The capillary effect created from the wire gauze material makes it suitable for very low liquid rate conditions. This combination makes it ideal for specialty and temperature-sensitive processes.

Montz-Pak type A3 wire gauze structured packing is best applied for demanding separations where thermal sensitive products are operating under vacuum conditions to keep the operating temperatures as low as possible. Montz-Pak type A3 wire gauze achieves outstanding separation efficiency with the lowest pressure drop per theoretical stage, making it the preferred choice for processing:

  • Specialty chemicals
  • Pharmaceuticals
  • Thermally unstable compounds

High Efficiency. Ultra-Low Pressure Drop.

With its wire gauze material and low pressure drop features, MONTZ-Pak type A3 wire gauze is engineered to maximize efficiency, without compromising pressure drop making it the perfect option for your deep vacuum and other demanding separations. 

Key Performance Advantages:

  • Excellent wettability from capillary-active wire gauze for high mass transfer
  • Extremely low liquid rates supported,down to 0.008gpm/ft² (0.02 m³/h/m²)
  • Minimal column height needed to achieve a high number of theoretical stages
  • High-capacity versions A-500M and A3-750M allow for even lower pressure drop per theoretical stage than conventional wire gauze structured packings

Available in Multiple Formats: 

  • Standard: A3-500, A3-700
  • High-capacity: A3-500M, A3-750M
  • Pilot Scale: A3-1000, A3-1200, A3-1900
