Roxburgh EMC

Roxburgh EMC has manufactured EMC filter products for more than 50 years, and today trades as a division of Alpha 3 Manufacturing Limited following an August 2025 rebrand. The company designs and produces mains, IEC inlet and chassis-mount EMC/RFI filters, including low-earth-leakage variants for medical equipment, from its 40,000 sq ft facility in Scunthorpe. Alongside its filter range, Roxburgh offers a pre-compliance EMC testing service and EMC consultancy support to its industrial and healthcare customers.
