Parker Hannifin announces new patent

The Industrial Gas Filtration and Generation Division of Parker Hannifin Corp. has announced the launch of a new patent for the metalworking industry. The patent is designed to optimise drainage within the SmogHog® SHM self-contained media mist collector, and provide 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, sealing 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 collects and coalesces on the fibre structure of the filter. As the droplet size grows, gravity drains the contaminants from the airstreams and out of the filter into the collection area.

The media used within this proprietary design provides an open 3D 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 fibre structure that removes the contaminants. 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 results particle capture.

The three-stage process includes a mist-stop prefilter; a fine fibre, aluminium mesh prefilter that reduces mist concentration and coarse contaminants; a primary filter engineered with PEACH® coalescing cartridges; and the final stage is a safety after-filter available in ASHRAE 95% oil mist rates filter or HEPA configurations.

“This invention joins many other industry-leading patents we have brought to industrial filtration,” said Jeff Canfield, Product Development Engineer, Industrial Air Filtration at Parker Hannifin. “This media technology is built into a tubular arrangement and this, coupled with the SHM three-stage filtration process, means a 99% reduction in mist concentration.”
