In addition to the main innovation hub in Trosa, the Group has local R&D facilities in Germany for comfort air filters and clean room filtration; in France and the U.S. for comfort air systems; in Malaysia for comfort air, clean room and AMC filtration, and in China for comfort air filters. “From these global R&D bases we can research and develop products for the worldwide air filtration market, including filters for the gas turbine industry,” says Anders Sundvik, Vice President for R&D. “We also have a number of mobile lab stations around the world to test filters right on the customer’s premises, in virtually any type of industry. Our filter research includes the development of filters using the most modern filter media, such as nano-fibres. We also design and build our own filter production equipment.” This global R&D network ensures that the product portfolio is steadily maintained, improved and advanced across all Camfil Farr business areas. It also drives the development of new innovative filters and solutions.

OUT Exhaust fumes, diesel particulates and ozone are making city air worse and lowering air quality considerably. As described in this issue, sulphur dioxide, nitrogen oxide and other air contaminants are creating serious health problems. At the same time, regulations are becoming stricter. Camfil Farr’s “City” series of molecular filters for urban pollution – City-Flo XL®, CityCarb ®, City-Flo ® and CitySorb ® – represent the ultimate filtration solution for indoor air quality control. These filters combine a highperformance particle filter and highly effective broad-spectrum carbon filter in a single device. For example, CityCarb and City-Flo are used for enhanced IAQ and odour control in comfort ventilation applications. The extra

Six energy-saving collectors instead Roche Spain contacted Camfil Farr, which proposed one dust collector per room. With this design, Roche could use the dust collectors independently, as required by production in each room, to save energy. Roche is now using six Gold Series GSC02s with explosion vents, the BIBO safe change system for cartridges, and double butterfly valve continuous line discharge for dust containment. The distance from the collection point to the dust collectors, and the relatively small air flow, required only medium-pressure fans for greater energy savings.

filters in the dust collectors for the coating line. Since replacement filters for dust collectors were an area that Camfil Farr has not worked with AstraZeneca before, a comparison test was arranged with our cartridge filters, which feature state-of-the-art HemiPleat pleating technology and a nano-fibre layer. HemiPleat filter media use synthetic beads to hold the pleats of the cartridge open. The pleat spacing is therefore wider than in competitive cartridges, which are packed too tightly to maximize media use. In HemiPleat 2/2012
Hospital delivery with surgical precision Cardiothoracic surgery is highly complex and requires the most sterile operating conditions to prevent post-operative infection. Camfil Farr’s CamHosp-R ceiling for operating theatres is specially designed to meet the highest surgery standards, as exemplified by a recent precision delivery to a hospital centre near Paris, France. The hospital needed a new operating theatre ceiling with a vertical, unidirectional air flow. Other requirements included fast delivery – a new surgical team was about to join the staff – and a comfortable, noiseless and no-draught work environment. Low energy consumption was important.

As the air supply is extremely clean, the filters have a long life expectancy and their very low pressure drop also reduces energy consumption.
