HARLEYSVILLE, Pa., June 29, 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 an order, totaling more than $900,000, to supply a large automotive parts supplier with several Duall brand scrubber systems. This order is expected to ship during the fourth quarter of the Company's current fiscal year.

The scrubber systems, which are designed to treat acid mists emitted from a plating on plastics operation, include several exhaust fans and PVC ducting. All equipment will be manufactured at the Met-Pro Environmental Air Solutions facility in Owosso, Michigan.

"This order continues our strong recent sales performance, which has totaled approximately $4.6 million of large project orders this month," stated De Hont. "It follows previous announcements for two large orders received earlier this month for Duall brand equipment and reinforces the reputation of Duall as the technology of choice for field-proven air pollution control systems. We are very encouraged by the recent uptick in large project new order activity and remain optimistic that we will receive more orders of this type in the near future."
