Mark 7 Transformer Breather


The Mark 7 Transformer Breather is made to protect equipment that operates under high mechanical stress. Manufactured from weld mild steel, the Mask 7 Transformer Breather is capable of withstanding shock parameters, bumps and vibrations found in electrical tractions such as trains and other similar vehicles.

An economical yet effective way to control moisture, the Mark 7 Transformer Breathers are fitted with oil-seals bowls and filled with Envirogel (Orange-Indicating Desiccant) instead of regular granular material to give the breather a much higher dust attrition resistance. Designed for easy maintenance, the breather only requires periodic inspection of oil level and replacement of Envirogel when it changes colour from orange to green, indicating saturation.

The Mark 7 Transformer Breather comes in three different models, with different level of body length to suit your application needs.
