Met-Pro's Environmental Air Solutions Business Unit Receives Equipment Orders Totaling in Excess of $1.0 Million

Harleysville, PA, February 5, 2010 - Raymond J. De Hont, Chairman and Chief Executive Officer of Met-Pro Corporation (NYSE:MPR), announced today that the Company's newly-formed Environmental Air Solutions business unit has received three orders for its Duall brand air pollution control systems. The first two systems are for industrial applications, including treatment of industrial acid gas and particulate emissions from a plasma arc furnace at a U.S. Army munitions facility, and treatment of sulfur
dioxide emissions from a carbon and graphite manufacturing facility. The third system is designed for municipal odor control at a wastewater treatment facility. The combined total of these orders is more than $1.0 million. Two of the orders are expected to ship in the second quarter and one is expected to ship in the third quarter of the Company's current fiscal year ending January 31, 2011.

The scope of supply for these orders includes Duall chemical scrubbers, venturi particulate collectors, exhaust fans, controls and instrumentation. The chemical scrubbers will utilize horizontal centrifugal recirculation pumps manufactured by the Company's Fybroc business unit. All three of the systems will be manufactured in the Met-Pro Environmental Air Solutions Owosso, Michigan facility.

"These orders demonstrate the strength of the Duall brand in both the municipal and industrial air pollution control markets," said De Hont. "They reinforce Duall's reputation as a market leader and are further examples of Met-Pro's ability to provide solutions that utilize our diverse product brands. We are encouraged by our success in being selected for these projects and are optimistic that circumstances are improving for the release of similar projects we have been pursuing."
