Miller Leaman Helix Disc Filters are available in three different sizes: 2″, 2″ Super and 3″ models. The filters can be installed in any orientation. However, it is preferable to install them in the inverted position (¾” flush port at bottom). This helps the filtration system work optimally. As water enters the filter housing, a high velocity centrifugal action occurs, spiraling heavier particles (sediment and scale, etc.) away from the disc cartridge down to the base of the filter. These accumulated particles are then flushed from the filter via the ¾” flush port connection at the base of the filter (valve not included).
Key Features
- Large disc surface area, with three-dimensional depth
- Particles can be flushed while filter is in operation
- Several color-coded disc options available
- Centrifugal cleaning action minimizes maintenance
- Durable, corrosion-resistant
- Quick clamp lid assembly
- Pressure gauge ports molded into housing
