Parker Hannifin Announces New Metalworking Patent
OVERLAND PARK, Kan. — The Industrial Gas Filtration and Generation Division of Parker Hannifin Corp., a manufacturer of motion and control technologies, announced the launch of a new patent for the metalworking industry. The patent is designed to optimize drainage within the SmogHog® SHM self-contained media mist collector and provide best in class particulate removal efficiency and long filter life using state-of-the-art coalescing filter media technology.
The patent includes an area that supports the industrial filter elements that seal the upper and lower plates of the filter, a liquid collection area, and a reservoir in the base section to drain away the liquid that coalesces during operation. Suspended liquids collect and coalesce on the fiber structure of the filter, the droplet size grows, and gravity drains the contaminants from the airstream and out of the filter into the collection area.
The media used within this proprietary design provides an open 3-D depth matrix structure that separates the liquid droplets from the airstream, into three airflow paths, radial, axial, and helical, removing 99% of contaminants. Air passes directly through the thickness of the media, impacting the fiber structure removing the contaminant. The media then forces a great amount of the airflow to take a stair-step path, improving particle removal, and the third path creates a corkscrew pattern that increases dwell time and resulting particle capture.
“This invention joins many other industry-leading patents we have brought to industrial filtration,” said Jeff Canfield, product development engineer, industrial air filtration, Parker Hannifin. “Preveil®, PulsePleats®, and ProTura®, to name a few. This media technology is built into a tubular arrangement. Coupled with the SHM three-stage filtration process our customers will see a 99% reduction in mist concentration.”
The three-stage process includes a mist-stop pre-filter; a fine fiber, aluminum mesh pre-filter that reduces mist concentration and coarse contaminants; a primary filter engineered with PEACH® coalescing cartridges; and the final stage, a safety after-filter, is available in ASHRAE 95% oil mist rates filter or HEPA configurations. This patent is known as U.S. Patent US-2018-0339255-A1. For more information, visit www.parker.com/airquality.
