FOR IMMEDIATE RELEASE

Peerless Mfg. Co. Reports Second Quarter Fiscal Year 2005 Results

Dallas, Texas – February 11, 2005 – Peerless Mfg. Co. (Nasdaq: PMFG), today reported its operating results for the second quarter of fiscal year 2005 ended December 31, 2004.

     The Company reported second quarter revenues from continuing operations of approximately $10.8 million, a decrease of approximately $5.6 million, or 34.1%, compared to revenues from continuing operations of approximately $16.4 million for the second quarter of fiscal 2004. The Company recorded a net loss from continuing operations of approximately $464,000, or ($.15) per diluted share for the quarter, compared to net earnings from continuing operations of approximately $609,000, or $.20 per diluted share for the comparable period last year. Loss from discontinued operations during the period was $33,000, or ($.01) per diluted share, compared to a loss of $142,000 or ($.05) per diluted share for the same period last year. Net loss for the period was approximately $497,000, or ($.16) per diluted share, compared to a net earnings of approximately $467,000, or $.15 per diluted share for the same period last year.

     The Company reported revenues of $22.1 million from continuing operations for the six months ended December 31, 2004, compared to revenues from continuing operations of approximately $33.2 million for the same period last year. The Company recorded a net loss from continuing operations of approximately $573,000 or ($.19) per diluted share for the period, compared to net earnings from continuing operations of approximately $1.35 million, or $.44 per diluted share for the comparable six-month period last year. Loss from discontinued operations during the period was $53,000, or ($.02) per diluted share, compared to a loss of $77,000 or ($.03) per diluted share for the same six-month period last year. Net loss for the period was approximately $626,000 or ($.21) per diluted share, compared to net earnings of approximately $1.27 million, or $.42 per diluted share for the same six-month period last year.

     Mr. Sherrill Stone, Chairman and Chief Executive Officer of the Company, stated, “The reduction in the current fiscal year’s revenue relates primarily to the completion in last year’s period of a major $15 million contract, which has not been replicated in the current period. The market conditions continue to be challenging for our Environmental Systems business unit with primary constraints on growth attributable to reduced new power plant construction and timing uncertainties surrounding compliance with environmental regulations. We have also been experiencing significant steel price increases in our Separation Filtration Systems business, which is impacting this business unit’s short-term profitability. However, there continues to be a number of nuclear power plant refurbishment projects, and as we mitigate the aforementioned steel price cost issue, this business’ fundamentals should return to more normal historical levels. Overall, the Company’s fundamentals remain strong, our balance sheet is strong, and we continue to expect an acceleration of revenues in the latter half of calendar year 2005 and 2006. We continue to be encouraged by the relative stability of our backlog ($34 million at December 31, 2004) and our gross margins.”

     Commenting on several recent major orders, Mr. Stone commented, “In the past sixty days, Peerless (and its subsidiary Peerless Europe Limited) has received contracts totaling over $6 million for new natural gas processing facilities and pipelines in the Middle East and Canada. We have also received contracts totaling in excess of $4 million for Environmental Systems at coal-fired power plants located in Minnesota and Massachusetts, and for a new gas turbine power plant under construction in Florida.”
