Dear Shareholders:
Bill Cook, Chairman, President and Chief Executive Officer
Donaldson is now deeply integrated into the global economy.
We are committed to growing our business on that basis –
addressing our worldwide end markets with sales, distribution
and manufacturing that allow a local response to our Customers’
needs. 2005 presented both global opportunities and global
challenges. The bottom line is, we had another great year and
our 16th consecutive EPS record.
This was also a year of transition for the leadership of our Company. My predecessor and mentor,
Bill Van Dyke, retired from the Company and Board. While he will be a tough act to follow, he also
leaves behind both a great company and a time-tested strategy.
We changed our strategy over 20 years ago with the objective of transforming ourselves from a cyclical
U.S. based company into a well diversified portfolio of filter businesses around the world. The theory
was that if we were in enough different filter businesses in different geographies running on different
cycles, that in aggregate we would have a stable platform for delivering consistent financials and above
average returns for our Shareholders.
That strategy has worked. 2005 represented another revenue record and our 16th consecutive earnings
record. The world around us will continue to change. We will adapt to these changes and continue to
execute our strategy to deliver the same goal. And that goal is the same one we have been focused on
since the mid-1980’s – providing superior returns to you, our Shareholders.
Operational Summary
Our revenue increased by $180 million to a new record of $1.6 billion. We saw solid strength on both
sides of our company with Engine Products sales up 14 percent and Industrial up 11 percent.
One of the challenges we encountered was in our gross margins. In the first half of the year, higher
steel prices affected margins. During the second half of the year, margins were again under pressure
from higher petroleum based raw materials and freight costs. In total, these were the most significant
inflationary pressures we have experienced since the early 1980’s. Fortunately, we were able to offset
these through a combination of selective price increases and very extensive cost reduction initiatives
with our Customers. Our people around the world did a magnificent job dealing with this challenge.
The bottom line is that we dealt with the challenges. Earnings per share were a record $1.27, up 8 per-
cent over the $1.18 reported in fiscal 2004, and net income was another record at $110.6 million.
Outlook
We enter fiscal 2006 on solid footing: The economic conditions in almost all of our end markets remain
good. As we started the year, our total order backlog was up 11 percent over the prior year.
In our Engine Products segment, our NAFTA heavy truck Customers are expecting strong build rates to
continue through calendar 2006. Our NAFTA construction and mining OEMs also continue to see robust
conditions. Our overseas Engine businesses also have good order backlogs. In summary, based on the
orders backlog we have in hand and the positive feedback from our Customers, we expect an increase
in Engine Product sales of about 10 percent in 2006.
Groundbreaking in Wuxi
We are building two new plants in
Wuxi, China in 2006. These plants
are our fifth and sixth manufacturing
facilities in China.
Czech Republic Plant
To meet European demand for our
industrial filtration systems, we will
build a new manufacturing facility in
Kadan, Czech Republic in 2006. This
plant will serve our Western European
customers while allowing us to better
serve the fast-growing Eastern
Europe market.
Two growth initiatives worth noting in our Engine Products segment: PowerCore™ filters and our diesel
emissions solutions.
PowerCore is a filtration technology breakthrough that allows us to offer our Customers a significant
innovation and value improvement. Using PowerCore, we now have won 36 new vehicle platforms at
our OEM Customers. In addition, we have made another 60+ PowerCore proposals for new platforms.
The bottom line on PowerCore: we expect to see continued strong PowerCore sales growth over the
next several years with sales up another 40 percent during 2006.
In diesel emissions, we’ve identified two significant growth opportunities. The first is related to the clean-
up of the exhaust of existing fleets of diesel powered vehicles. This is being driven by state and local
governments, whose main area of focus is school buses. In 2005, we sold $12 million in retrofit solutions
for existing fleets and expect to experience continued growth in ’06 and beyond. The second opportunity
is related to the upcoming 2007 federal regulations for the reduction of diesel emissions for all new heavy
duty diesel powered trucks. We have already won the emissions business for two major truck engine
platforms with several more of our proposals in the bidding process. All in all, we expect to see our
current $50 million truck exhaust and emissions business in North America grow to $150 million by 2010.
In the Industrial side of our business, global conditions are good, and we continue to execute our
growth plan around the combination of our industrial air filtration and Ultrafilter™ product lines. We
acquired Ultrafilter three years ago and are very pleased with how it has fit into our existing Industrial
businesses. In our Special Applications business, we are expecting a strong ’06 due to the continued
strength in both our disk drive filter and membrane businesses. Finally, conditions in our gas turbine
business are improving modestly, as we see good growth opportunities internationally. Combining all of
our Industrial related businesses, we’re expecting 2006 sales growth in our Industrial Products Segment
in the high single-digits.
Donaldson’s Global Presence
Three years ago, our mix of international versus North American sales passed the 50 percent mark.
This was a major milestone. We now have more than 11,000 Donaldson employees in 35 countries around
the world, supporting our global OEM, aftermarket and industrial Customers.
In North America, our 4,500 employees serve our Customers in the U.S., Mexico, and Canada. Our main
global R&D center is in the U.S. We now have 14 production plants within NAFTA in addition to distribu-
tion centers and sales offices.
Farewell to Bill Van Dyke
In the 10 years Bill Van Dyke led Donaldson
Company as its President, CEO and Chairman,
our company grew into a $1.6 billion international
enterprise with operations in 35 countries and
more than half of its revenue originating outside
the U.S.
Even more important, Bill built an organization
that delivered unprecedented financial results
to our Shareholders: 16 consecutive years of
record earnings growth, a 21 percent average
annual return to our Shareholders. If he had one
mantra, it was always, “if we take care of the
Shareholders, the company and its people will
prosper.”And they most definitely have.
Bill’s definition of what ‘good’ looked like was
setting earnings records – each and every year.
He vowed that we would never take a year off,
and that Shareholders would reward us for that
consistency.
To that end, under his thoughtful leadership,
Bill built a management team who brought depth
and seasoned business acumen to the company.
Bill was a leader who gave people a chance to
succeed – or fail – and who surrounded himself
with top talent, then allowed them to do their
jobs. He was all about results, and had little
patience for excuses.
Bill demanded the same of himself as he did of
others. He worked tirelessly as a leader and a
coach and demanded excellence in everything
he did as a manager, a CEO and as Chairman
of our Board. At the same time, Bill always kept
things in perspective, drawing clear distinctions
between those things the company could control
and those it couldn’t.
Bill, for all that you did to build this great
company – thank you! Best wishes for a
wonderful retirement!

Our Europe, Middle East and Africa regions now employ more than 2,800 employees. We cover this area
through an extensive network including 37 sales offices, 14 production plants and five distribution centers.
Our Asia Pacific region employs more than 3,700 employees in 19 sales offices, eight production plants
and three distribution centers.
From a long-term strategic standpoint, 2005 was distinguished by the number of significant investments
to further grow our International businesses. Some highlights include:
• Significant expansion of our existing plants in Australia and Italy. At our Australian plant, where
we manufacture engine air filters and industrial air filtration equipment, we doubled the facility size.
At our Italian plant, we also doubled the size of the plant to meet demand for our liquid filters for the
European market.
• We opened our first plant in Thailand. This Class 100 clean room will supply filters for the rapidly
growing disk drive industry. We expect to produce almost 200 million disk drive filters in our first
year of production in Thailand.
In fiscal 2005, we spent more than $50 million in capital expenditures – the majority to support the growth
in our international operations. And in fiscal 2006, we expect an even bigger year – $85 million to $95
million as we continue to invest in our future. Our plans include two more plants in Wuxi, China. One
will be dedicated to the production of air filters to support our Engine Customers throughout Asia. The
second new plant will help expand our industrial air filtration production. In Europe, we are building our
second plant in the Czech Republic; this plant will manufacture industrial air filtration equipment. We
are also building a new distribution center in South Africa to help serve our Customers’ growing need for
replacement filters throughout the African continent. And finally, we are working on several other major
expansion projects that are in the proposal stage. Stay tuned.
The filtration markets we participate in represent a great business opportunity. There is a growing need
for improved filtration throughout the world – we see examples of this in the news daily. Fortunately, we
have the right technology to apply to many of those critical needs, so it is easy to be excited about our
opportunities. To achieve our goals, we will continue to execute our strategy, leveraging both the out-
standing capabilities and commitment of our Employees. Finally, our goals remain the same – by taking
good care of our Customers, we provide for our Shareholders and our Employees.
Sincerely,
Bill Cook, Chairman, President and Chief Executive Officer
