Marksman 740 Retrofit Filter Elements
The Marksman™ 740 Series Filter Element is a direct retrofit to the industrial 740 format. The cartridge utilizes an optimized axial pleat geometry for high efficiency, low flux (flow per unit area), and exceptional dirt-holding capacity, which yields long on-stream life and low differential pressure.
- Poly-Fine® XLD Media
- Poly-Fine II Media
With the addition of this new 740 format to Pall’s Marksman family of elements, users can now enjoy an even broader range of filter media and grades offered by a single source. The clear advantage of the Marksman 740 Series filter is broad chemical compatibility and economy of use. The Marksman 740 Series filter is available in two media options.
Poly-Fine® XLD Media
Poly-Fine XLD (Extended Life Depth) media is optimized for large cartridge geometry filters. Poly-Fine XLD media is a hybrid media offering the best of depth media performance in a pleated format. Constructed of all polypropylene, it offers wide chemical and service compatibility.
Poly-Fine II PFT Media
Poly-Fine II media is the ideal media for true surface filtration. Poly-Fine II media offers the optimum in a high dirt-holding capacity pleated filter geometry. Also constructed of all polypropylene, it presents versatility and broad chemical compatibility.
All Marksman Series filters are manufactured in Pall’s ISO 9001 state-of-the-art facilities and contain the most advanced melt-blown media available. Our proprietary processes produce media for the sole purpose of filtration.
Thorough attention to every detail of the manufacturing process assures a product with unmatched performance:
- Unsurpassed consistency
- High void volume1 for high dirt-holding capacity
- A broad range of chemical compatibility for maximum application utility
1 Void volume is defined as that fraction of the media not occupied by media fibers. Pall’s proprietary construction yields a media with over 80% void space, allowing the greatest dirt-holding capacity (DHC) and consequently long filter life, which translates into fewer element change-outs, reduced operator exposure, and lower overall operating costs.

2 Pressure drop in PSID per GPM water for a single 38 in (965 mm) element. Multiply this value by the required flow to determine the total aqueous pressure drop. For fluids other than water, multiply differential pressure by viscosity (cP).
Q. 1. Will the Marksman 740 Series Filter fit my existing housing?
- The Marksman 740 Series filter provides an intrinsic 360-degree positive seal utilizing a 226 O-ring, which permits a direct fit into an existing vessel. This filter is also available in a “short” option for other competitive variants of this filter format. For details, please consult your Pall representative.
Q. 2. What are the filter grade and filter media options available for Marksman 740 Series Filters?
- The Marksman 740 Series Filters are available in two filter media options with the following filter grade ratings –
Poly-Fine® XLD Media - 1.5, 3, 4.5, 10, 20, 30, 70
Poly-Fine II Media - 1, 3, 5, 10, 20, 40, 70, 90, 150
