Dual-Gradient Melt-Blown Spun Polypropylene Sediment Filters

SP-DD Series

The SP-DD Series of SpiroPure sediment filters utilizes dual-gradient polypropylene filter media to provide a higher dirt holding capacity and excellent chemical resistance. The dual-gradient filtration makes them a perfect choice for removing sediment from all residential, rural, municipal, and commercial applications.

Reduces sediment for a variety of water filtration needs, including for all residential, rural, municipal, and commercial applications
Available in nominal sizes of: 10x4.5 and 20x4.5
Available nominal filtration ratings of: 1, 5, 10, 20, 25, and 50 microns
Temperature rating of 40°F to 145°F (4.4°C to 62.8°C)
Dual-gradient design combines pre- and post-filter features, reducing the need for a step-down filtration system
A higher micron outer gradient layer reduces the load on the inner, smaller micron layer for more efficient filtration and a much higher dirt-holding capacity and cartridge life than similarly sized cartridges
