Met-Pro Corporation's Environmental Air Solutions Business Unit Receives $2.1 Million Order

Harleysville, PA, January 7, 2013 - Met-Pro Corporation (NYSE:MPR) announced today that the Company's Environmental Air Solutions business unit has received a $2.1 million order from a global manufacturer of consumer and industrial building products to supply a Bio-Reaction® brand biological air pollution control system. This order is expected to ship in the third quarter of the Company's next fiscal year.

The unique system, which utilizes Met-Pro's patented Bio-airSPHERES® media for digestion and final breakdown of contaminants, is specifically designed to remove Hazardous Air Pollutants (HAPs), such as formaldehyde and methanol, and convert them to carbon dioxide and water vapor that can be safely released into the atmosphere. It is expected to meet or exceed the customer's emission requirements and also potentially reduce their existing capital and operating costs for air emissions treatment.
"The Bio-Reaction® brand, which utilizes state-of-the-art biological technology, is a perfect complement to our Met-Pro Environmental Air Solutions' dust collection, thermal oxidation, and chemical scrubber technologies. Our 'Total Air Solutions' value proposition allows us to better address the increasingly more stringent environmental regulations and the global focus on greenhouse gas reduction," said Raymond J. De Hont, Met-Pro's Chief Executive Officer and President. "The growing pipeline of opportunities for additional Bio-Reaction® brand orders allows us to remain optimistic about future orders of this type."
