Stop right there! Achieving zero leakage when it matters most Manual butterfly isolation dampers I n high end, sensitive ventilation systems such as those found within nuclear, biotechnology, pharmaceutical, research and hospital facilities it is usually vital that the plant is kept running, often 24 hours a day, 7 days a week. In these instances one of the hardest things to accomplish is isolating part of the system completely and efficiently for vital maintenance or other necessary processes. Incorporating secure and reliable isolation mechanisms in order to make stopping as safe as running is therefore a key factor in improving 10 PECM Issue 18 plant design and installation efficiency which is essential in these facilities, and favourable in any engineering or manufacturing plant. Zero leakage has become the mantra of specialists M C Air Filtration in helping engineers at key sites across the UK to achieve complete shutdown at key stages throughout their facilities. For over 30 years the firm has been at the forefront of air movement and filtration technology associated with high end industries. They are now market leaders in the manufacture of standard and bespoke high integrity isolation dampers suitable for use in a wide range of critical ventilation and process applications. The firm’s range of high efficiency ( EP ) filters and the associated housings have become the product of choice within nuclear power generation, reprocessing and decommissioning as well as being extensively used in biotech and pharma both in the UK and overseas. The MC circular butterfly type isolation damper was initially developed to provide positive isolation to their own range of high integrity bag
