Miller-Leaman, Inc. introduces their Helix Filters; designed to remove particles and other contaminants from process cooling water used in injection-molding and extrusion operations. The filters are available with a three-dimensional polypropylene disc media (Helix HD Series) or a stainless steel screen (Helix HS Series). The Helix HD Series is available in multiple color-coded disc sizes representing different micron ratings; the Helix HS Series is available with a wide range of stainless steel screen options.
As dirty water enters the filter housing, a high velocity spinning action occurs, spiraling heavier particles (sand, sediment, etc.) away from the disc/screen cartridge, down to the base of the filter housing. These accumulated particles are then flushed from the filter via the 3/4” flush port connection. The filter housings include pressure gauge ports so the customer can monitor the differential pressure across the filter, telling them when the filter needs to be serviced. The filters are available in (3) model sizes; a regular 2” model, a 2” Super model, and a 3” model. The inlet/outlet connection sizes can be reduced for smaller line sizes. All models have a quick-release stainless steel clamp lid assembly for easy access to the internal disc or screen cartridge.
