Mark 7 Transformer Breather

Mark 7 transformer breather is a moisture solution for protecting equipment operating under high mechanical stress. Made from mild welded steel, it is designed to withstand bumps, vibrations, and shock parameters commonly found in electric traction vehicles such as trains. The breather is filled with orange indicating silica gel and is fitted with an oil-seal bowl, a cost-effective way of controlling moisture.

The transformer breather is equipped with beaded desiccants with higher dust attrition resistance than standard granular material. Desiccant replacement is required only when the silica gel changes colour from orange to green, making it easy to maintain. With three different models, the transformer breathers come in varying body lengths to fit specific needs.
