             ALLIED HEALTHCARE NET INCOME INCREASES FOR FIRST THREE QUARTERS
                   BUT FALLS IN THE THIRD QUARTER OF FY 2006

ST. LOUIS, MAY 3, 2006 - ALLIED HEALTHCARE PRODUCTS, INC. (NASDAQ: AHPI)
REPORTED TODAY THAT ITS NET INCOME FELL ABOUT 42 PERCENT TO $236,000, OR 3 CENTS
PER DILUTED SHARE, DURING ITS THIRD QUARTER ENDED MARCH 31, 2006, VERSUS
$408,000, OR 5 CENTS PER DILUTED SHARE, FOR THE THIRD QUARTER LAST YEAR.

     HOWEVER, FOR THE FIRST THREE QUARTERS OF FISCAL 2006, ALLIED'S NET INCOME
INCREASED ABOUT 23 PERCENT TO $1,020,000, OR 13 CENTS PER DILUTED SHARE, VERSUS
$828,000, OR 10 CENTS PER DILUTED SHARE, FOR 2005'S FIRST THREE QUARTERS.

     SALES INCREASED IN THE THIRD QUARTER TO TOTAL $14.8 MILLION. SALES FOR THE
FISCAL YEAR'S THREE QUARTERS INCREASED ABOUT $1.2 MILLION.

     SALES INCREASES REFLECT THE SIGNIFICANT BACKLOG THAT DEVELOPED IN THE
PREVIOUS YEAR. ORDERS FOR FISCAL 2006 HAVE BEEN SLUGGISH, SAID EARL REFSLAND,
PRESIDENT AND CHIEF EXECUTIVE OFFICER. A MAJOR FACTOR IN SLOW ORDER VOLUME HAS
BEEN THE CONTINUING DOWNTURN IN THE CYCLICAL U.S. HOSPITAL CONSTRUCTION MARKET,
REFSLAND SAID.

     MEDICAL EXPENSES FOR THE NINE-MONTH PERIOD INCREASED MORE THAN $400,000
OVER THE PREVIOUS YEAR UNDER THE SELF-INSURED PORTION OF THE BENEFIT; $280,000
OF THIS INCREASE OCCURRED IN THE THIRD QUARTER. ALLIED'S MEDICAL COSTS PER
EMPLOYEE HAVE GROWN AT AN ANNUAL RATE OF ABOUT 9 PERCENT SINCE 2002, BUT IN
FISCAL 2006 MEDICAL COSTS PER EMPLOYEE INCREASED 21 PERCENT OVER THE PRIOR YEAR.
THIS INCREASE

<PAGE>

IS CONSIDERED AN ANOMALY, AND THE COMPANY'S MEDICAL COSTS ARE EXPECTED TO RETURN
TO PATTERNS THAT REFLECT MARKET TRENDS IN THE FUTURE, REFSLAND SAID.

     ALLIED HEALTHCARE PRODUCTS, INC. IS A LEADING MANUFACTURER OF RESPIRATORY
CARE PRODUCTS, MEDICAL GAS EQUIPMENT AND EMERGENCY MEDICAL PRODUCTS USED IN A
WIDE RANGE OF HOSPITAL AND ALTERNATE CARE SETTINGS.
