The Camfil Group is a producer and developer of air filters and clean air products. Camfil is also a global air filtration specialist with 24 production units and R&D centres in four countries in the Americas, Europe and the Asia-Pacific region. The Group, headquartered in Stockholm, Sweden, has approximately 3,000 employees and sales in the range of SEK 4.3 billion. International markets account for more than 90 percent of sales. The company’s business is to provide customers with air filtration products and services within four main segments: Comfort Air, Clean Processes, Power Systems and Safety & Protection.


The global Camfil Group[1] started out as a family business in the town of Trosa, Sweden, located about 70 km (43 mi) south of Stockholm. Camfil was founded in Trosa in 1963 by the Larson family, still one of the company’s principal owners, as a joint venture with Cambridge Filtration Corporation in the United States. In 1983, the family bought Cambridge’s shares. Camfil was wholly owned by the family until 2000, when Ratos AB, a Swedish private equity company, received 29.7 percent of the shares in connection with the acquisition of Farr in the United States, which was then listed on NASDAQ.[2] Ratos sold its shares in 2010 to the other owners, families Larson and Markman.[3]

Camfil has always been profitable since the start of operations more than four decades ago. Today, the company is the global leader[citation needed] in clean air technology and air filter production with operations in more than 50 countries.

Comfort Air[edit]

The Comfort Air business area accounts for almost half of Group sales. Most air filters for this segment are installed in ventilation systems in schools, offices, homes, hospitals and airports, among other facilities.

Since the Comfort Air market consists mainly of replacement filters, operations in this segment are relatively insensitive to fluctuations in the economy. Customers include real estate management companies, local government agencies and buildings, as well as companies providing ventilation service to offices, hotels, restaurants, airports and similar public facilities.

In Europe, bag filters are dominant, with Hi-Flo being the most common product. In the U.S., compact filters with pleated filter media are more common. The best known[citation needed] is Camfil’s 30/30 pleated panel filter.

Clean Processes[edit]

Clean air is an important requirement in many production processes. There are stringent requirements for ultra-clean air in cleanroom applications. Semiconductors, pharmaceuticals, food and beverages have to be produced in strictly controlled environments, where very small and undesirable particles can be devastating and lead to biocontamination, spoilage and high costs. Paint spraying facilities for the automotive industry and hospital operating theatres are other applications in this business sector. Camfil supplies complete ceiling systems for hospital surgery and has also pioneered a range of supply and exhaust housings specifically for the biopharmaceutical industry, including high-temperature filters and bag-in, bag-out systems for containing contaminants.

In clean manufacturing processes, filtration often takes place in several stages, where pre-filtration is first carried out to protect the high-efficiency filters, which are much more complex and consequently more expensive. Pre-filters here are similar to those used in the Comfort Air sector. High-efficiency filters often cover the entire ceiling in a cleanroom environment. Megalam is a typical final stage filter for clean processes. The need for gas filtration is steadily increasing. Camfil has developed the Gigapleat for this purpose, among other molecular filters.

Power Systems[edit]

Protecting equipment such as gas turbines, compressors and diesel engines is a key Camfil segment. Air filtration and noise control equipment has been supplied to thousands of installations all over the globe.

Air filtration for air intakes, enclosures, silencers and cooling systems for gas turbines are one of the cornerstones of Camfil’s expanding international business.

Today, Camfil products are being used around the world to protect gas turbines from erosion and fouling. Land-based, offshore, and marine systems are supplied, as well as retrofits and upgrades.

Safety & Protection[edit]

Emissions from dirty and potentially dangerous processes, such as nuclear power generation, mining, laboratory research and chemical factories, can harm human beings and nature. Camfil's filter solutions are designed to prevent emissions of foul-smelling and unhealthy substances that constitute a direct threat to people and the environment.

The high-tech end of this market consists of biocontainment systems – a Camfil specialty – which include everything from systems for sterile and particle-free air in mini-environments, to special high-security housings for high-risk laboratories, buildings and environments, biosafety cabinets for hazardous materials, high-temperature filters for sterilisation processes, bag in-bag out systems for handling contaminants and specially designed terminal and exhaust housings. Biopharma facilities, highsecurity research labs, nuclear power plants and chemical factories use these systems, among other customers. Dust collection for pollution control and product recovery is another fast-growing area in this segment. The main markets are currently North America and Europe, where saving energy and increasing production efficiency, while controlling indoor air quality, is a challenging aspect of plant management. The metalworking, pharmaceutical and mining industries are typical customers.
