Reducing ventilation costs
In the last issue, I talked about our goal to become sustainable and how important it
is to us. Leading efforts in this area is a way to maintain our global leadership posi-
tion, retain the respect of the market and strengthen our credibility as the greenest
air filtration company on the planet. This is summarized inside, but you can get all
the details about our programme, our progress and what we expect to accomplish
in Camfil Farr’s Sustainability Report, available for downloading on our website.
Energy conservation is closely linked to sustainability. In
today’s energy debate, governments are leaning heavier
on commercial and industrial building owners to master
the fundamentals of energy efficiency and increase
their greenness. Using the correct filters with the right
filter efficiency and lowest pressure drop will reduce
the energy consumption of HVAC systems sharply while
maintaining a healthy indoor climate for occupants and
enhancing the sustainability performance of buildings.
We recently hosted a series of well-attended national
seminars in Sweden on the theme of energy savings and caring for the environment.
Guest speakers and our experts focussed on energy efficiency and climate change,
energy classifications of filters, indoor air quality and related health problems, AHU
fan performance, and heat exchangers and energy recovery, among other topics.
The message was crystal-clear: building ventilation systems are energy-intensive
(see also “Saving energy” page 4). We calculated – in the case of Sweden – that as
much as 1.4TWh in energy is needed to move air through filters in all the country’s
air handling systems. And we know from experience that the right filters with the
right pressure drop can have a significant impact on this power consumption and
the carbon footprint of Sweden’s buildings.
This is only one example from one country, and we don’t have to mention the
health benefits of using better quality filters. At one of the seminars, an external
expert also noted how the use of poor quality filters reduces the efficiency of a
ventilation system: for example, if a substantial amount of dust accumulates in a
heat exchanger, its efficiency will fall about 50 percent, costing about 1,700 kWh
in extra energy per year and apartment unit in a building.
It’s no news to us – for years we have preached the benefits of certified filter
performance, LCC analyses and high-efficiency filters with low pressure drop.
Quality filters may cost a little more, but their longer term benefits – in terms of
reduced energy consumption, higher IAQ, fewer filter changes, and less waste – pay
off every time – and in many cases, several times over.
Enjoy this issue and read about the latest air filtration solutions we have
supplied to valued customers.

An industry first
Camfil Farr is the first air filtration company in the world to publish a corporate Sustainability
Report. The recently released report, describing the company’s initial sustainability actions, goals
and performance indicators, is available for downloading at camfilfarr.com in an easy-to-read and
environmentally friendly online version. Excerpts from the report can also be found on special pages
that you can link to from the start page.
The report is being published on a voluntary basis to describe our efforts to become a truly
sustainable enterprise. In Camfil Farr’s view, sustainability is vital for continuing growth as well as
essential for understanding the social and environmental concerns of customers, employees and
other stakeholders. As described in the report, the company is setting up a consistent approach to
communicating sustainability through five main directions: energy efficiency, indoor air quality, green
2008 products, the supply chain, and risk assessment and management.

Tests vs. real-life efficiency
“A number of filter manufacturers are promoting filtration products that use filter media that will not perform in service as well as it
performs in standard ASHRAE testing,” comments Danja McMillan, Camfil Farr’s Northeast Region Sales Manager in the U.S. “Because of
this discrepancy, filtration users think they are purchasing a product that will deliver a level of filtration based on an ASHRAE test report.”
“However, these products do not achieve the level of particle removal efficiency shown in the ASHRAE test report when the filters
are installed in the user’s system. Thus, the user needs reliable information on what the differences are between ‘real-life’ efficiency filter
efficiency and ‘test report’ filter efficiency. With our in-situ tests, customers get the proof they need, right in their own AHUs, right on their

a lower pressure drop
Hi-Flo XL combines cost efficiency, environmental thinking and low energy consumption all in the same filter
series. The Eurovent-certified Hi-Flo XL range has been streamlined and now features 36 models instead Standard filters
of 134, making selection and stocking easier for customers and distributors. Hi-Flo XL’s new one-piece
plastic frame and high-tech filter media are proprietary designs developed by Camfil Farr’s R&D Department.
The low-weight media and frame are also eco-friendly because they are completely incinerable and cheaper to
dispose of. When it is time to change the filter, you simply place the used filter in a burnable bag.
The energy saver
The new Hi-Flo XL generation is specifically designed for energy savings over a wide application range. The
Lower pressure drop development
filters are designed to fit virtually all types of air handling units used in commercial and industrial ventilation for greater savings
Compared with most standard pocket filters on the market, Hi-Flo XL can reduce the operating cost of Standard filters
a ventilation system by more than 20 percent since it keeps pressure drop low over a longer period. The
ventilation system operates more efficiently, over a longer period of time, and uses less energy as a result.
It has been estimated that Hi-Flo XL can save building owners more than 1 euro per Pa (pressure drop) per
filter and year.
When air flows as freely as possible through the pockets of an air filter, with no resistance, the filter will
perform better. In Hi-Flo XL, this is achieved with perfectly conical pockets based a newly developed seam
