CECO ENVIRONMENTAL ANNOUNCES $3,900,000 IN NEW CONTRACTS

NEW YORK, August 1, 2003- CECO Environmental Corp. (NASDAQ: CECE), announced today that it has been awarded five significant new contracts.

The first contract, valued at approximately $1,300,000 is for the design, fabrication, and installation of a regenerative thermal oxidizer for an Ethanol Manufacturing Facility located in the Midwest. This contract was secured by CECO's subsidiary, CECO Abatement Systems. This is the seventh regenerative thermal oxidizer that CECO Abatement Systems has sold to Ethanol Producers. CECO believes that it has more equipment of this type sold to this industry than all of its competitors combined.

CECO also recently received a contract, valued in excess of $800,000, to provide and install a partitioning system that minimizes the need for ventilation and the presence of dust for a specialty glass furnace located in the Southeastern United States. This contract is being performed by CECO's Kirk & Blum subsidiary.

Kirk & Blum has also received a contract to provide mechanical systems for a Food Processing Facility located in the Midwest. This contract is valued at approximately $600,000.

CECO's Busch International subsidiary, located in Pittsburgh, Pennsylvania, has received two significant new contracts. The first, valued at about $800,000, is for a ventilation system at a Midwestern Steel Mill. This equipment is similar to that provided for the same customer at another facility under a contract that was announced in March. Busch International has also received, through it's office in the United Kingdom, a contract, valued at approximately $400,000, to provide fume exhaust systems for a rolling mill located in China.

Phillip DeZwirek, Chairman of CECO Environmental Corporation, stated, "we feel that the diversity of our customer base, as these contracts illustrate, is a key strength of our company. We are confident that, as the economy improves, the inroads that we have made into various industries will continue to strengthen our competitive position."
