Met-Pro Corporation Announces Financial Results

for the Second Quarter Ended 7/31/2004

Harleysville, PA, August 24 – Raymond J. De Hont, Chairman and Chief Executive Officer of Met-Pro Corporation (NYSE: MPR), today announced that second quarter sales were $20.4 million compared to $18.6 million for the same period last year and $4.7 million higher than the first quarter of this year. First half sales totaled $36.0 million compared to $35.6 million for the same period last year.

Net income for the second quarter ended July 31, 2004 totaled $1.6 million or slightly higher than the same period last year and $0.8 million higher than the first quarter of this year. For the first half, net income totaled $2.4 million compared to $2.9 million during last year's first half.

For the second quarter, both basic and diluted earnings per share were $0.19 per share compared to $0.19 per share for the same period last year and $0.09 higher than the first quarter of this year. For the first half, both basic and diluted earnings per share were $0.29 per share compared to $0.35 per share earned during last year’s first half.

“Met-Pro’s first half earnings were adversely impacted by a combination of product mix, pricing pressures and higher raw material costs”, said De Hont. “Our quotation activity remains high in both operating segments; however, while the net sales and income from operations of our Fluid Handling Segment have increased significantly during the first half, the net sales and income from operations of our Product Recovery/Pollution Control Segment have also been, and continue to be, adversely impacted by the delayed timing of the issuance of customer purchase orders for several larger dollar projects. In an effort to improve our gross margins and profit levels, we continue to review our operations and expenses, and have begun raising prices where feasible.”

On June 9, 2004 the Company paid a quarterly dividend of $.0725 per share to shareholders of record at the close of business on May 28, 2004. In addition, the Board of Directors, at their meeting on June 9, 2004, declared a quarterly dividend of $.0725 per share payable on September 9, 2004 to shareholders of record at the close of business on August 27, 2004. This represents a 7.4% increase over the corresponding dividends paid during the same periods last year.

This dividend represents the thirtieth consecutive year the Company has paid a cash or stock dividend.
