Met-Pro Corporation's Systems Business Unit Receives Equipment Order Totaling Approximately $500,000


Harleysville, PA, July 14, 2009 - Raymond J. De Hont, Chairman and Chief Executive Officer of Met-Pro Corporation (NYSE:MPR), announced today that the Company's Systems business unit has received an order, totaling approximately $500,000, to supply a thermal oxidation system to a landfill gas recovery and purification facility in the southern United States. This order is expected to ship during the third quarter of the Company's current fiscal year.

The equipment to be supplied will destroy off gases from a landfill gas recovery and purification system to significantly reduce the level of methane emissions, which when compared to carbon dioxide, have more than 20 times the impact on the greenhouse effect in the Earth's atmosphere. The equipment supplied will also include provisions for future energy recovery.

"This is the second thermal oxidizer ordered through the same customer in less than a year illustrating their confidence in Met-Pro Systems' highly energy efficient oxidation equipment and Systems' ability to uniquely tailor their designs to meet customer requirements," stated De Hont. "This order reinforces Met-Pro Systems' reputation as a supplier of choice for field-proven thermal oxidation systems. It represents another example of Met-Pro's wide range of solutions to help solve the challenges of protecting our environment while serving business and industry around the world."
