Development and Commercialization Plan for a Grid Electrostatic Filter


This picture shows the experimental GEP connected to the Cameron cleanroom. Clean air is blown into the cleanroom through the duct near the top of the cleanroom’s wall.

Mr. John Dunn, Mr. James Cunningham, Dr. Xinli Jia, and Professor John McLaughlin are working on the development and commercialization of a grid electrostatic filter (GEF) for various indoor applications. An experimental grid electrostatic precipitator (GEP) was manufactured at Cameron Manufacturing & Design, which has supported the project. The GEP was delivered to Clarkson in the spring of 2010 and underwent extensive testing over a period of several months. Measurements of particle concentration were performed using a Wide-Range Particle Spectrometer, and it was found that the maximum collection efficiency of the GEP was roughly 85%.  In July, Dr. Jia developed an innovative use of porous filter material in the device that resulted in much higher collection efficiencies – collection efficiencies greater than 99% have been achieved with little or no impact on air velocity. Xinli Jia, John Dunn, and John McLaughlin applied for a provisional patent for the GEF in November 2010. The team is now exploring applications of the GEF technology as a pre-filter for cleanrooms and as a means of eliminating welding or machining fumes in industrial metal fabrication operations. The GEF offers higher efficiency and much lower power consumption than the technologies currently used in the above applications. The work is currently being supported by a grant from the Commercialization Assistance Program (CAP) of the Syracuse Center of Excellence (COE) and CenterState Corporation for Economic Opportunity (CEO). The Clarkson team is receiving support through a subcontract from Cameron. The team is also receiving assistance from Linda Hartsock, who is Vice President of Innovation & Technology Initiatives at CenterState Corporation for Economic Opportunity and Director of the Syracuse Clean Tech Center.

In January 2011, John McLaughlin established Verdant AirTech LLC (“Verdant Air”), which is based in Potsdam. Verdant Air is dedicated to developing and selling price-competitive air purifying systems that deliver a high level of air purity (>99%) while achieving energy reductions of at least 50% relative to existing technologies. The ultimate goal is to design different systems that can be applied in several different fields, e.g. metal fabrication plants, coal burning plants, diesel engines where the resulting fumes are regulated; industrial cleanrooms, hospitals in areas where the internal environment and air quality are measured and controlled, and shopping centers and households, where the indoor air purity is of concern. The initial goal of the company is to develop, test, and commercialize a device to remove metal-working fumes with low energy consumption and a competitive price. Once the company has begun operations, it is expected that the members of the project team will be involved in the operations of the company.

The project team has received support from the Deputy Director of Clarkson’s Shipley Center for Innovation, Mr. Matthew Draper, in developing the commercialization plan for the GEF as well as setting up Verdant Air. Mr. Draper is also working closely with the team in preparing for the 2011 Creative Core Business Competition.

Mr. Dunn is an inventor who has served as a consultant for Cameron Manufacturing and a Research Scientist at Clarkson University. Mr. Cunningham is a Business Developer/Principal Consultant with Alliance for Manufacturing & Technology, which is located in Binghamton, NY. Dr. Jia is a Post-Doctoral Research Associate at Clarkson.
