World leader in air filtration – “Clean air – a human right?

Camfil1

“By the end of the world”, in Trosa, you´ll find the world leader in manufacturing air filters – Camfil. The Swedish family owned company with more than 5 billions of turnover on a global market is unknown outside the business, but was on the space shuttle together with Christer Fuglesang because of it´s world leading filtration technique.

Camfil was founded 1963 because of nuclear power. The Swedish government had established a nuclear power research center in Studsvik. Nuclear energy was something new,a research area that attracted the sharpest of brains. Gösta Larson, the founder of Camfil, realized an opportunity and became an agent for American manufactured industria filters. He figured out that nuclear power plants need air filters – filters of a new technology. Mr Larson went and convinced the technicians and researchers to sign a contract. He kept his promises and started the production with three employees.

Camfil of today has 3700 employees, 25 manufacturing plants around the world, sales companies in 25 different countries, agents and representatives in more than 50 countries. The turnover is 5,5 billion SEK (2014).

The research and development is built up with a new Tech-Center in Trosa, Sweden, where Camfil has the test and research equipment to investigate the pollutants in the air and with the SEM microscope look at nano particles, smaller than 0,1 µm. This is extremely important to be able to see when one is developing new filters for different applications. Within the TechCenter in Trosa there´s also the one and only full scale molecular laboratory, for this business, in the world. It´s built up to be able to test the efficiency and the lifetime of full sized filters by different gases that affects filters in real environment. Select the right carbon impregnation for a certain air cleaning purpose, and calculate it´s efficiency and life time. To be able to know what´s needed in different parts of the world Camfil has built eight 40´ containers with possibility to measure and compare four different filters in each container. The measurements of particle concentration, humidity and temperature are transferred to a computer in Trosa. The eight containers are placed in various cities around the world. In total Camfil has 70 persons around the world working with research to improve the indoor air quality (IAQ) for people’s health.

Camfil is segmented in different business units, Comfort air, Clean Processes, Power Systems, Air Pollution Control, Airborne Molecular Contamination.

Camfil is a member of all technical committees, as for example ASHRAE in the US and Eurovent, the European branch organization, around the world and takes initiative to improve the standards and methods to guarantee the performance of air filters in all types, from coarse filters to fine air filters, micro filters and molecular filtration.

Camfil6Camfil is an active member of the European branch organization, Eurovent, where all standards and new development regarding fine air filters are discussed and promoted. The latest project was to improve the European Energy Efficiency Classification for fine filters. The guide line, Eurovent 4/21-2014, is decided and the program, with classifying  filters in A+  –  E,  from January 2015.

 

 

 

 

Camfil8Indoor Air Quality
People drinks 2-3 liters of water, eats about 1 kg of food and breathe around 25 kg of air every 24 hours. We are very keen on food and beverage but do we know what we breathe? We need good air filters to remove the particles and pollution the ventilation unit brings in by the air. Not all filters are the same – even when they are in the same class. The new European standard for air filters (EN779:2012) came into force in 2012. Its purpose is to classify air filters based on their lowest filtration efficiency, Minimum Efficiency (ME). The standard is an initiative that we welcome and a step towards better indoor environments. The new standard will help to eradicate a number of problems. One of these is presented by electrostatic charged synthetic filters. While such filters can demonstrate good initial filtration efficiency, they discharge extremely rapidly. This entails a considerable deterioration in their air cleaning ability. Unfortunately, one result of the foregoing is that far too many European properties are now using F7 class filters that have ME values of between 5 and 10 percent. This means that as much as 90 to 95 percent of the contaminants in the outdoor air find their way into buildings and pollute the indoor environment. By basing classification on ME value, the new standard will force these filters out of the market. At the same time, it will contribute to the development of synthetic filter materials offering considerably higher particle separation.
