Keeping the city

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.

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. Technical constraints were
