For release:       IMMEDIATELY

                   AIRGAS REPORTS THIRD QUARTER EPS OF $0.28

RADNOR, PA - January 28, 2004 -- Airgas, Inc., (NYSE: ARG) today reported
earnings for its third quarter ended December 31, 2003.  Net earnings for
the quarter were $20.9 million, or $0.28 per diluted share, compared to
$16.7 million, or $0.23 per diluted share, in the same period a year ago.
The results for the recently completed quarter include a non-recurring
after-tax gain of $1.7 million, or $0.02 per diluted share, at National
Welders Supply Company, a joint venture affiliate.

Third quarter sales increased 3.8% to $451.9 million, and total same-
store sales were up 1% compared to the same quarter a year ago,
reflecting some improvement in manufacturing and other industrial
segments.  Same-store sales in the Distribution segment were up 1%,
driven by a 3% gain in hardgoods and a slight gain in gas and rent.  Same-
store sales for the Gas Operations segment increased 1%.

Net earnings for the nine months ended December 31, 2003 were $0.79 per
diluted share compared to prior year results of $0.69 per diluted share.
The nine months ended December 31, 2003 include insurance-related losses
of $2.8 million ($1.7 million after tax), or $0.02 per diluted share, for
previously announced incidents at two of the Company's facilities, offset
by the gain of $0.02 per diluted share mentioned above.  The nine months
ended December 31, 2002 included charges of $2.9 million ($2.2 million
after tax), or $0.03 per diluted share, primarily related to a special
charge for the integration of the Air Products acquisition ($2.7
million).

"I was pleased to see the sales momentum in the third quarter," said
Airgas Chairman and Chief Executive Officer Peter McCausland.  "We saw
clear evidence of industrial recovery with good growth in our hardgoods
business.  The recovery is still in its early stages, so our outlook
remains cautiously optimistic.  However, as the industrial economy
continues rebounding, we expect our higher margin gas business to respond
as well, contributing favorably to overall profitability.  Fourth quarter
earnings are expected to range from $0.26 to $0.29 per diluted share."



Free Cash Flow for the nine months ended December 31, 2003 was $57
million compared to $71 million in the prior year.  The year over year
decline is attributable to inventory build related to the economic
recovery and capital expenditures in growth areas including medical,
microbulk and bulk gases.  The Company reduced adjusted debt by $51
million through the third quarter.  The definition of free cash flow and
a reconciliation to the attached Consolidated Statement of Cash Flows, as
well as the definition of adjusted debt and a reconciliation to the
balance sheet are attached.

McCausland continued, "Earlier this week, we announced our intent to
acquire the majority of BOC's U.S. packaged gas business.  This is a good
opportunity for Airgas, one which fills in some gaps in our national
network and which will bring additional specialty gas capabilities.  This
proposed acquisition, which is expected to close in mid 2004, will build
on our strengths and will help us meet our commitment to build value over
the long term.  We are positioned well financially to execute this
transaction."

29, 2004, beginning at 11:00 a.m. Eastern Time.  Access the

See attached notes.




Notes:

(a)  Special charges of $2.7 million ($1.7 million after tax) for the nine
     months ended December 31, 2002 consist of a restructuring charge related
     to the integration of the business acquired from Air Products in the
     fourth quarter of fiscal 2002 and costs related to the consolidation of
     the Company's procurement functions.  The special charges include
     facility exit costs associated with the closure of certain Airgas (the
     "Company") facilities and severance for approximately 130 employees.

(b)  Equity in the earnings of unconsolidated affiliates for the
     quarter and nine months ended December 31, 2003 reflects a $1.7
     million non-recurring after-tax gain.

(c)  The Company participates in a securitization agreement with two
     commercial banks to sell up to $175 million of qualified trade
     receivables.  Net proceeds from the securitization were used to
     reduce borrowings under the Company's revolving credit facilities.
     The amount of outstanding receivables under the agreement was
     $156.2 million and $158.9 million at December 31, 2003 and March
     31, 2003, respectively.

(d)  Since October 1999, the Company has leased certain real estate and
     equipment from a grantor trust (the "Trust") established by a
     commercial bank under a sale-leaseback arrangement.  The Trust was
     not consolidated for financial reporting purposes.  Effective July
     1, 2003, the Company elected to early adopt Financial Accounting
     Standards Board Interpretation No. 46 ("FIN 46") with respect to
     the Trust, which requires the consolidation of the Trust.  The
     consolidation of the Trust resulted in the Company recording
     assets of $29 million and debt of $42 million, while eliminating a
     deferred gain of $13 million that was previously carried on the
     balance sheet as a long-term liability.  Consolidation of the
     Trust was a non-cash transaction.

(e)  Since June 1996, the Company has participated in a joint venture with
     National Welders Supply Company, Inc. ("NWS"), a producer and distributor
     of industrial gases based in Charlotte, North Carolina. Ownership
     interests in the joint venture consist of voting common stock and voting,
     redeemable preferred stock. The Company owns 100% of the joint venture's
     common stock, which represents a 50% voting interest. The Company does
     not hold a majority voting interest in the joint venture and, therefore,
     historically has used the equity method to account for its interest in
     the joint venture.



(e)  continued

     The Company has determined that NWS meets the definition of a
     "Variable Interest Entity" under FIN 46 and that the Company is
     the primary beneficiary of the joint venture.  Therefore,
     effective December 31, 2003, the Company elected to adopt FIN 46,
     as it applies to the joint venture, and consolidated NWS.  At
     December 31, 2003, the consolidation of NWS only affects the
     balance sheet.  There was no impact on net earnings or cash flows
     as a result of the consolidation.  The consolidation has the
     effect of eliminating the Company's $62 million investment in NWS
     and recording the joint venture's assets, liabilities and a
     corresponding minority interest liability.  The summarized impact
     of the consolidation of NWS at December 31, 2003 is reflected in
     the table below.  Beginning January 1, 2004, NWS' operating
     results will no longer be reflected as "Equity in Earnings of
     Unconsolidated Affiliates."  Rather, the operating results will be
     reflected broadly across the income statement with minority
     interest expense representing the after-tax portion of the
     operating results applicable to the preferred stockholders.
