Helix HD Series
Miller Leaman's Helix Disc Filter models are available in three sizes: 2",
2" Super and 3". The filters can be installed in any orientation; however, it is
preferable to install them in the inverted position (3/4" flush port at bottom). This
helps the filtration system work at its optimum. As water enters the filter housing, a
high velocity centrifugal action occurs, spiraling heavier particles (sediment, 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 3/4" flush port connection at the
base of the filter (valve not included).
The body contains one inlet and two outlets, allowing the filter to be installed at either
90 or 180-degrees. A threaded cap is supplied with the filter to terminate the outlet port
not being used. Inlet/outlet connections are available in NPT or Victaulic. The body
contains inlet and outlet pressure gauge ports (gauges not included). The gauges monitor
the pressure differential across the filter disc which determines when the disc cartridge
needs to be removed for maintenance.
Manufactured in Type 316 Stainless Steel, the quick-release clamp assembly is strong
and reliable. No tools are necessary to remove the clamp and filter cover when maintenance
The three-dimensional disc is ideal for filtering hard particles (such as sediment and
scale) and soft fibrous material (such as algae, bugs, cottonwood seed, etc.). The
color-coded discs are available in a variety of micron sizes (50, 100, 130, 200-Micron).
The lid is injection-molded, using an incredibly strong polyamide material. The
centrifugal action, created by the Helix Element, spirals heavier particles down to the
base of the filter. The particles are then flushed, either manually or automatically, from
the 3/4" flush port at the lowest point in the lid.

HOW IT WORKS
Dirty Water Enters the Filter Housing Through the Inlet Connection. As Dirty Water Passes
Through the Helix-Element, the Water Starts to Spin at High Velocity. This Centrifugal
Action Spins the Particles Away From the disc media, Minimizing Manual Cleaning Frequency.
As Particles Are Spun Down to the Base of the Filter, They are Flushed Via the 3/4"
Female Threaded Flush Port Connection. The Dirty Water Passes From the Outside to the
Inside of the disc. The grooves, molded into the surface of the three-dimensional discs,
trap the remaining contaminants in the water. After Passing Through the discs, the
Filtered Water Flows Upward and Exits the Filter Through One of the Outlets. The Outlet
Not Being Used is Terminated With a Threaded Cap.

*50, 100, 130, & 200 micron options available. Please specify
disc size when ordering. Example: HD-2SA-130 = 2" NPT Super with 130 - micron discs.
Disc cartridges for 2" regular models (HD-2NA and HD-2NW) and 2" Super models
(HD-2SA and HD-2SW) vary in size. The cartridge for the 2" regular models is
15.5" in height. The cartridge for the 2" super models is 20.5" in height.
This means that the 2" super models have approximately 40% more surface area for
filtration (186 sq. inches vs. 263 sq. inches).
