Ease of Use

Marksman filters come with a user-friendly design resulting in faster filter change-outs, simple maintenance, and reduced system downtime. The filters eliminate the need for compression plates, springs, and tube guides.

Marksman filters can be easily retrofitted into existing Size 1 and Size 2 bag housings and offer quick and easy change-outs. A single Size 2 Marksman series filter replaces up to 16 standard 10 inches (25.4 cm) filters. 



Marksman filters are designed to be used in normal process conditions and critical batches, unlike bag filters intended for short periods of usage during upset conditions and less critical production runs. These filters can serve as a complementary technology to existing bag filters.


Lower Operating Costs

High surface area and long service life lead to fewer cartridge change-outs and reduced disposal cost. One Marksman filter's life and filtration performance are equivalent to 10 standard 10 inches (25.4 cm) filters that offer additional savings.
