CECO ENVIRONMENTAL RECEIVES $900,000 EQUIPMENT
ORDER FOR STEEL INDUSTRY AND REPORTS
CONTRIBUTION MARGINS REBOUND IN SECOND QUARTER

NEW YORK, June 2, 2005 - CECO Environmental Corp. (NASDAQ:CECE), reported today that its wholly owned Busch International subsidiary has received an order for approximately $900,000 to provide a baghouse for a major steel making facility in the Midwest.

This is one of a series of orders received by Busch working with another CECO subsidiary, CECOaire, that are enabling customers to comply with new EPA requirements for the steel industry.

Rick Blum, President and COO of CECO Environmental, also reported that "contribution margins recognized thus far in the second quarter appear to have returned to anticipated levels reaffirming our belief that the unusually low margins in the first quarter were an anomaly due to a combination of conservative accounting methods and competitive pricing."

CECO reaffirms that its backlog continues to be maintained at record levels and the year remains 'back-end loaded.'
