The ‘R’ Transformer Breather provides an economic and efficient means of controlling the level of moisture entering the conservator tank during the change in volume of the cooling medium and/or airspace caused by temperature gradients.

All our Transformer Breathers are filled with Envirogel, which is a self-indicating silica gel desiccant. This desiccant is orange/yellow in colour when active, but turns green when saturated.

The ‘R’ Transformer Breather is manufactured from UV stabilised poly-carbonate. The clear polycarbonate body allows for clear visibility of the desiccant charge and enables users to check desiccant condition with ease.

The unit is mounted from a ¾” female pipe thread connection at the top of the breather. This connection point is also used for filling and emptying the desiccant within the breather. Two-way, low pres-sure valves are fitted in the base of the breather to ensure that the atmospheric air enters the desiccant when a negative pressure differential occurs within the equipment being protected.
