Summary
Product identification
The Pall Marksman™ NXA Series are High Capacity Melt Blown Depth Filter Elements.
Key features include:
- New, larger cartridge geometry
- Proprietary CoLD Melt™ fiber technology, similar to Pall’s Nexis® series filters
- Gradient pore structure
- Absolute rated at 99.9% efficiency with retention ratings from 4.3 to 72 µm
- Available to fit most Size 1 and Size 2 bag housings without hardware changes
- Available in 101.6 cm (40 in) for use in unique 101.6 cm (40 in) Marksman housings
- Inside-out flow design traps contaminant inside the element
- Unique sealing device adjusts to fit most bag filter housings
- Quick, easy change-outs
- Short length option to accommodate shorter baskets
Operating limits
- Filter grades: 5, 10, 20, 40, 70 µm
- Maximum operating differential pressure:
