Thank you for taking an interest in Roxburgh EMC. Since 1969 we have been designing and manufacturing EMC filters and noise suppression products, even before the 89/336/EEC legislation of January 1996. Our first ever EMC filter was of a unique cylindrical shape, the SDC range, which were sold to the market for almost 40 years before being replaced by the PC3 range; smaller and more economical… but we digress. Since 1969, much has changed in the EMC filter world especially at Roxburgh, not least our company name which has changed from Deltron Emcon to DEM Manufacturing. However, our brand Roxburgh EMC, remains strong and respected as the United Kingdoms largest manufacturer of EMC filters.
