Founded in 1996, GMT specialises in the environmental protection of oil immersed electrical transformers. Our solutions include the FILTRELEC range of filters, designed and assembled 100% in France, for treating rainwater contaminated by hydrocarbons.
Based in the south of France, we distribute our products worldwide. However, we are very keen to keep our know-how in France and Europe.
We have therefore made the choice to design and assemble our strategic products in France. This choice is fully in line with our commitments:


FILTRELEC filters ensure the continuous evacuation of run-off water from the retention tanks placed under electrical transformers. The filtered water is discharged into the natural environment in compliance with the requirements of the Clean Water Act.
Designed and manufactured in France, our F5, F15 and F6 Green filters undergo rigorous on-site checks by our R&D and quality teams. Each product is checked before dispatch to guarantee optimum performance.

France is recognised internationally for its high standards of quality and safety. Within the GMT Group, our teams are fully committed to continuous improvement. Innovation and quality are at the heart of our missions, in order to offer ever more reliable and high-performance solutions.
In fact, we are ISO 9001 certified, in recognition of the quality of our products and services. Our internal processes are designed to meet current standards and the most demanding expectations of our customers.

We offer environmental protection solutions for electric power transformer stations. Our services include: consultancy, design and assistance.
