ENVIRONMENTAL TECTONICS CORPORATION
                   ANNOUNCES FIRST QUARTER FISCAL 2005 RESULTS

         Southampton, PA: July 14, 2004 - ENVIRONMENTAL TECTONICS CORPORATION
(AMEX: ETC) (the "Company") today announced financial results for the fiscal
first quarter ended May 28, 2004.

         For the fiscal first quarter ended May 28, 2004, ETC had a net loss of
$1,461,000 or ($.19) per share (diluted), versus net income of $70,000, or $.01
per share (diluted) for the corresponding period of fiscal 2004. Sales for the
first quarter of fiscal 2005 were $6,175,000, an increase of $45,000 or 0.7%
from the first quarter of fiscal 2004. Increased sales were evidenced in our
Aircrew Training Systems (ATS) (up $2,008,000, 91.4%) and Environmental (up
$744,000, 338.2%) business units, with a partial offset being across-the-board
decreases in the other business units. ATS benefited domestically by the sale of
two Gyro-IPTs and by increased work on a centrifuge project in Malaysia.
Environmental evidenced higher sales both domestically and in the international
market.

         Geographically, domestic sales in the first quarter of fiscal 2005 were
$2,050,000 as compared to $2,824,000 in the first quarter of fiscal 2004, a
decrease of $774,000 or 27.4%, as a significant reduction in Sterilizer sales
(down $1,567,000, 92.1%) was only partially offset by increases in ATS (up
$776,000, 611.0%) and Environmental (up $475,000, 399.2%). The decrease in
Sterilizers reflected reduced activity for a large domestic Ethylene Oxide
("ETO") sterilizer project. Domestic sales represented 33.2% of the Company's
total sales in the first quarter of fiscal 2005, down from 46.1% for the first
quarter of fiscal 2004. U.S. Government sales in the first quarter of fiscal
2005 were $447,000, 7.2% of total sales, as compared to $335,000, or 5.5% of
total sales in the first quarter of fiscal 2004. International sales for the
first quarter of fiscal 2005 were $3,678,000 as compared to $2,971,000 in the
first quarter of fiscal 2004, an increase of $707,000, 23.8%, and represented
59.6% of total sales in the current period versus 48.4% for the prior year
period. The increase in international sales represented the aforementioned
centrifuge work in Malaysia.

         Gross profit for the first quarter of fiscal 2005 was $994,000 as
compared to $2,287,000 in the first quarter of fiscal 2004, a decrease of
$1,293,000 or 56.5%. This decrease reflected a 21.2 percentage point decrease in
the gross profit rate as a percent of sales. The reduced gross profit rate as a
percent of sales reflected across the board reductions in all business areas,
most notably Simulation and Hyperbaric. Environmental gross profit suffered from
installation cost overruns totaling $333,000 for projects in China and Italy.
ATS experienced unbudgeted expenses of $163,000 to upgrade an airplane simulator
in Egypt. Simulation expended additional development funds of $131,000 for two
international projects.

         William F. Mitchell, ETC's President and Chairman, stated, "The results
for the first quarter of fiscal 2005 primarily reflected the negative impact of
the following significant factors:

         o  negative gross margins on some long-term international projects that
            experienced difficulties during installation and completion in the
            field
         o  additional development funds not covered in the selling price for
            some simulation projects, although it is anticipated that the extra
            functionality will make the products more flexible and marketable to
            fire schools and academies throughout Europe
         o  continued selling, general and administrative costs for litigation
            and contract claims
         o  higher cost of capital reflecting the February 2003 refinancing

         Since the end of the fiscal quarter a few of the problem jobs have been
completed which should allow for improved gross margins going forward.

         Despite the difficult world conditions, during the first quarter we
managed to book over $5 million in new contracts. This included five monoplace
chambers, mostly for sites in the local Philadelphia area, a $2.2 million order
for two multiplace hyperbaric chambers for an international customer, and
approximately $650,000 in new sterilizer orders. We expect a large portion of
the revenue from these contracts to be reflected in this fiscal year.

         An additional major milestone was achieved last week when we concluded
negotiations with a major U.S. defense contractor for a significant contract to
build aircraft simulators in our Polish subsidiary. These will support a major
acquisition of U.S. aircraft by the Polish Air Force. While the impact on this
fiscal year's results will be minimal, the financial impact on Poland's results
for the next two fiscal years should be very favorable.





         As was announced on June 2nd, we successfully factory tested and the
customer accepted the first G-FET II equipped as an Authentic Tactical Flight
Simulator. This device combines the latest available flight simulation
technology with tactical flight maneuvering to provide high performance aircraft
pilots with realistic air combat training. We are seeing serious interest from
several International customers.

         Our Simulation division has received preliminary indications from a
major airport for the purchase of software services to simulate airport
certification and emergency drill training exercises in addition to the ones
already implemented.

         Finally in April EnTCo, our entertainment subsidiary, announced its
first international installation in Blackpool, England and its first domestic
sale to the Incredible Pizza Company. Potential customer interest in this
subsidiary's products remains strong.

         The impact on ETC in the past two years of global economic and
political factors has been significant. However, I and your Company's management
remain firmly committed to developing the best product at a competitive price."

ETC designs, develops, installs and maintains aircrew training systems, public
entertainment systems, process simulation systems (sterilization and
environmental), clinical hyperbaric systems, environmental testing and
simulation systems, and related products for domestic and international
customers.
