HARLEYSVILLE, Pa., April 20, 2011 /PRNewswire/ -- Raymond J. De Hont, Chairman and Chief Executive Officer of Met-Pro Corporation (NYSE:MPR), announced today that the Company's Environmental Air Solutions business unit has received two orders totaling approximately $240,000 to supply Bio-Reaction® brand biological air pollution control products. These orders are expected to ship in the second and third quarters of the current fiscal year.

The larger order is for a bio-oxidation system that was specifically designed to include Met-Pro's patented Bio AirSphere™ media for the treatment of odorous volatile organic compounds (VOCs). The order is from Met-Pro's Chinese licensee for a system that will be installed at a petrochemical plant in the People's Republic of China. There are several other Bio-Reaction® systems installed in China for similar petrochemical wastewater odor applications.

The second order, which is for a bio-oxidation pilot system, is from a large U.S. based global manufacturer of consumer and industrial products. The pilot system will test the feasibility of using Met-Pro's innovative and patented bio-oxidation technology to treat industrial air emissions and reduce both capital investment and operating costs at their various manufacturing facilities.

"Though small, these orders demonstrate the traction we are gaining with the Bio-Reaction® brand for industrial market applications," said De Hont. "They follow an announcement earlier this week of an Environmental Air Solutions order in excess of $620,000 received for Duall brand equipment to treat particulate and recover heavy metals."
