                                Pall Corporation

        Pall Corporation, incorporated in July 1946, together with its
subsidiaries, is a leading supplier of fine filters, principally made by Pall
Corporation or its subsidiaries using its proprietary filter media, and other
fluid clarification and separations equipment for the removal of solid, liquid
and gaseous contaminants from a wide variety of liquids and gases.

        We serve customers in two principal markets: Life Sciences and
Industrial. The two principal markets are further divided into five segments:
Blood and BioPharmaceuticals (which comprise the Life Sciences business) and
General Industrial, Aerospace and Microelectronics (which comprise the
Industrial business).

        During the past five years, we have continued our development and sale
of fluid clarification and separations products in a wide variety of markets.
Additionally, in fiscal 2002, we acquired the Filtration and Separations Group
("FSG") from United States Filter Corporation, significantly expanding our
presence in the Industrial market.


        Pall is a specialty materials and engineering company with the
broadest-based filtration, separations and purification capabilities in the
world. Our proprietary products are used to discover, develop and produce
pharmaceuticals, produce safe drinking water, protect hospital patients, remove
white blood cells from blood, enhance the quality and efficiency of
manufacturing processes, keep equipment running efficiently and protect the
environment. Requirements for product quality, purity, environmental
preservation, health and safety apply to a wide range of industries and across
geographical borders. We have a 57-year history of commercializing successful
products and continue to develop new materials and technologies for the Life
Sciences and Industrial markets and their increasingly difficult fluid
filtration, purification and separation challenges. We have an array of core
materials and technologies that can be combined and manipulated in many ways to
solve complex fluid separation challenges. These proprietary materials, coupled
with our ability to engineer them into useful forms, are the foundations of our
capabilities. Our proprietary materials enable us to provide customers with
products that are well matched to their needs, to develop new products and to
enter new markets. With the addition of FSG, we have enhanced our library of
proprietary materials and technologies with sophisticated offerings such as
asymmetric membranes, selective adsorption, melt-blown media, nano ceramic
membranes and metallic fiber media.


        Pall actively pursues only those applications in which its products can
make a substantial difference to the customer and especially targets projects
that will result in real gains in performance and economics. The products sold
are principally filters made with proprietary Pall filter media produced by
chemical film casting, melt-blowing of polymer fibers, papermaking and
metallurgical processes. Metal and plastic housings for our filters and a wide
variety of appurtenant devices are also made. Competition is intense in all of
our markets and includes many large and small companies in our global markets;
however, no one company has a significant presence in all of our markets.

        Pall's principal executive offices are located at 2200 Northern
Boulevard, East Hills, New York 11548, and its telephone number at that address
is (516) 484-5400.

                            The Selling Stockholders

        Pall issued and delivered the Shares to the Plans in satisfaction of all
or a portion of Pall's obligation to make annual contributions to the Plans.
Included in the Shares are 44,665 shares of Pall common stock which Pall issued
and delivered to the Plans in partial satisfaction of Pall's obligation to
contribute to the Plans or their predecessor plans with respect to Pall's fiscal
year ended July 28, 1990. Pall's board of directors, acting by its executive
committee, authorized the proper officers of Pall to deliver 210,000 additional
Shares to the Plans in partial satisfaction of Pall's obligation to contribute
to the Plans with respect to Pall's fiscal year ended August 3, 2002.

        During the past three years, the Plans have had no position, office or
other material relationship with Pall or any of its affiliates apart from
providing retirement benefits to the employees of Pall and its subsidiaries. In
addition, the Plans own no shares of Pall common stock apart from the 254,655
Shares. The Plans are offering all the Shares pursuant to the offering under
this prospectus and accordingly will own no shares of Pall common stock after
completion of this offering.

        Reed, Conner & Birdwell, Inc. acts as an investment adviser to the Plans
 (the "Investment Adviser") and has sole authority to direct The Bank of New
 York, as trustee of the Plans, to sell any or all of the Shares from time to
 time, and to make delivery of such Shares to the purchasers thereof.



                      The Offering and Plan of Distribution


        Pall will pay all expenses in connection with the sale of the Shares by
 the Plans. Depending upon market conditions, the Plans may, in the sole
 discretion and at the direction of the Investment Adviser, from time to time
 sell all or some of the Shares.

        The Plans will not sell the Shares at any predetermined price or
 pursuant to any pre-arranged plan of distribution, the time, price and manner
 of sale, if any, being in the Investment Adviser's discretion. The Shares may
 be sold in brokerage transactions (which may include block trades and ordinary
 brokers' transactions) on the New York Stock Exchange, in privately negotiated
 transactions, in the over-the-counter market, in underwritten public offerings,
 and otherwise. The price at which the Shares may be sold will be the prevailing
 market price (plus customary or negotiated brokerage commissions) in the case
 of brokerage sales executed on the New York Stock Exchange or in the
 over-the-counter market, and the price plus brokerage commissions or discounts
 agreed upon by the parties in the case of privately negotiated transactions and
 underwritten public offerings.




        Any broker-dealers that act as principals in connection with the sale of
Shares will be "underwriters" within the meaning of Section 2(11) of the
Securities Act of 1933; the Plans, The Bank of New York as trustee of the Plans,
and any broker-dealer that acts as agent in connection with the sale of the
Shares may be "underwriters" within the meaning of Section 2(11); and any
compensation these broker-dealers receive, and any profit they realize from the
resale of the


                                       4





Shares while acting as principals, might be considered as underwriting discounts
or commissions. Because the Plans may be "underwriters" within the meaning of
Section 2(11) of the Securities Act, they will be subject to the prospectus
delivery requirements of the Securities Act for offers and sales of the Shares,
including delivery through the facilities of the New York Stock Exchange as
provided in Rule 153 under the Securities Act.

        The Plans also may resell all or a portion of the Shares in open market
transactions in reliance upon Rule 144 under the Securities Act, if the Plans
meet the criteria and satisfy the requirements of Rule 144.

        If either Plan notifies Pall that it has entered into any material
arrangement with a broker-dealer for the sale of Shares through a block trade,
special offering, exchange distribution or secondary distribution or a purchase
by a broker or dealer (including underwritten public offerings), Pall will file
a supplement to this prospectus, if required, pursuant to Rule 424(b) under the
Securities Act, disclosing

       o    the name of the participating broker-dealer(s),

       o    the number of Shares involved,

       o    the price at which such Shares were sold,

       o    the commission  paid or discounts or  concessions  allowed to the
            broker-dealer(s), where applicable,

       o    whether  the  broker-dealer(s)  conducted  any  investigation  to
            verify the  information in or  incorporated  by reference in this
            prospectus, and

       o    other material facts of the transaction.


                                       5





                          Common Share Purchase Rights

        On November 17, 1989, the board of directors of Pall Corporation,
pursuant to a favorable advisory vote of its shareholders, adopted a Shareholder
Rights Plan and pursuant thereto declared a dividend of one common share
purchase right (a "Right") for each outstanding share of Pall common stock. The
distribution was made to the holders of record of common stock outstanding on
December 1, 1989, and is being made with respect to all shares of common stock
issued thereafter until the earliest to occur of the Distribution Date (as
defined below), the date on which the Rights are redeemed, and the expiration
date of the Rights (December 1, 2009 unless the expiration date is extended
prior to that date).

        Each Right, when it becomes exercisable, will entitle the registered
holder to purchase from Pall one share of Pall common stock at a price of $80,
subject to adjustment in certain events, including stock splits, occurring
subsequent to the date of this prospectus. Until the Distribution Date, the
Rights (a) will not be exercisable, (b) will be evidenced by the certificates
for the common stock registered in the names of the holders thereof and not by
separate Right certificates, and (c) will be transferable with and only with the
common stock, and one Right will be associated with each share of common stock,
subject to adjustment in certain events.

        The "Distribution Date" is defined as the earlier to occur of (1) 10
days following a public announcement that a person or group of affiliated or
associated persons has acquired beneficial ownership of 20% or more of the
outstanding Pall common stock (such person or group being defined as an
"Acquiring Person"), or (2) 10 business days (or such later date as may be
determined by action of the Board prior to such time as any person or group
becomes an Acquiring Person) following the commencement of, or announcement of
an intention to make, a tender offer or exchange offer the consummation of which
would result in the beneficial ownership by a person or group of 20% or more of
such outstanding common stock.

        The Rights have certain anti-takeover effects. A description of the
Rights is set forth in Amendment No. 1, dated April 20, 1999, to Pall's
Registration Statement on Form 8-A for the registration of the Rights pursuant
to Section 12(b) of the Exchange Act, which Amendment is a document incorporated
by reference in this prospectus as provided below.


                                  Legal Matters


        The validity of the Shares has been passed upon by Carter Ledyard &
Milburn LLP, Two Wall Street, New York, New York 10005. Heywood Shelley, counsel
to Carter Ledyard & Milburn LLP, is a director of Pall.
