Exhibit 99.1


FOR IMMEDIATE RELEASE


        PEERLESS MFG. CO. REPORTS FIRST QUARTER FISCAL YEAR 2004 RESULTS


Dallas, Texas - November 10, 2003 -- Peerless Mfg. Co. (the "Company"), (Nasdaq:
PMFG), today reported its operating results for the first quarter ended
September 30, 2003.

The Company reported first quarter revenues from continuing operations of
approximately $16.8 million, an increase of approximately $3.5 million, or
26.3%, compared to revenues from continuing operations of approximately $13.3
million for the first quarter of fiscal 2003. The higher revenues were primarily
due to an increase in revenues from the Environmental Systems business unit. The
Company recorded net earnings from continuing operations of approximately
$740,000, or $.24 per diluted share for the quarter, compared to a net loss from
continuing operations of approximately $1.1 million, or $.35 per diluted share
for the comparable period last year. Earnings from discontinued operations
during the period were $65,000, or $.02 per diluted share, compared to a loss of
$288,000, or $.10 per diluted share for the same period last year. Net earnings
for the period were approximately $805,000, or $.26 per diluted share, compared
to a net loss of approximately $1.3 million, or $.45 per diluted share for the
same period last year.

Mr. Sherrill Stone, Chairman and Chief Executive Officer of the Company, stated,
"We are extremely pleased with the results of our first quarter. The excellent
results during this quarter follow the strong results achieved by the Company
during the fourth quarter of fiscal year 2003. We believe that we are beginning
to see the positive operational impact of our restructuring initiatives
undertaken during the last fiscal year. We continue to be encouraged by the
relative stability of our backlog, which was $38 million at September 30, 2003.
We are also encouraged by a recent increase in the number of inquiries for our
nuclear, marine and environmental products. We do however continue to operate in
a challenging market environment, and as such may experience softness in our
revenues from quarter-to-quarter. During the quarter, we also sold our boiler
operations. While the net gain on the sale added only $.03 to our diluted share
earnings, we believe the real long-term benefit will arise from our focus on our
core operational units: Environmental Systems and Separation & Filtration
Systems."
