Met-Pro Corporation Acquires Patented Biological Technology

• Provides new global municipal and industrial market opportunities

• Strengthens Met-Pro’s “Total Air Solutions” value proposition

Harleysville, PA, October 12, 2010 – Raymond J. De Hont, Chairman and Chief Executive Officer of Met-Pro Corporation (NYSE:MPR), announced today that the Company has acquired substantially all of the assets including the patents and technology of Bio-Reaction Industries LLC (“BRI”), a pioneer in environmentally friendly air pollution control systems utilizing state-of-the-art biological technology to eliminate volatile organic compounds (VOCs), hazardous air pollutants (HAPs), and odors.

“The acquisition of these assets significantly enhances Met-Pro’s competitive position in both the municipal and industrial global markets by providing not only state-of-the-art biological technologies, but also a broad global reference base of satisfied customers,” stated De Hont. “BRI’s patented biological technology, which is a perfect complement to our Met-Pro Environmental Air Solutions’ thermal oxidizer and chemical scrubber technologies, strengthens our “Total Air Solutions” value proposition, allowing us to better address the increasingly more stringent environmental regulations and the global focus on greenhouse gas reduction. We believe our extensive relationships within the municipal market will enable us to quickly grow BRI’s municipal market share, while BRI’s relationships within a diverse base of industrial markets provides opportunities to introduce Met-Pro’s broad range of solutions to new markets.”

BRI’s bio-oxidation systems are the new standard in air pollution control technology, utilizing naturally existing microbes to biologically break down HAPs and VOCs. BRI offers a modular, reliable bio-oxidation solution that achieves the highest removal efficiency of VOCs for any air phase biological treatment system in the world. BRI’s innovative vapor-phase bio-technologies provide a cost effective way to comply with regulatory requirements, treating high volume, low concentration air streams and delivering dramatic energy savings for a wide range of applications, including municipalities, paints and coatings, wood products, building materials, and the chemical processing industry. BRI’s patented Bio-airSPHERES enhance microbial activity and air contaminant digestion, effectively reducing carbon footprints and significantly cutting operating costs when compared with other less efficient technologies.

Terms of the transaction were not disclosed. It is expected that the acquisition will have no impact upon current year earnings but will be accretive to earnings in the Company’s fiscal year ending January 31, 2012.
