The R series transformers breathers are designed to provide ease of use for checking and maintaining the desiccant condition. The breather’s body is made of UV-stabilised and shatterproof polycarbonate windows that enable quick checks. The unit has two-way, low-pressure valves in the base that allow air to enter the breather only when there is a negative pressure within the equipment.

The transformer breather is mounted on a ¾” female pipe thread connection at the top of the breather, allowing for easy filling and emptying of the desiccant. The R series breathers are available in different sizes – R, R1, and R2 – to cater to various transformer requirements. The R3 breather includes two R1 breathers, saturating one completely before the other, providing more time for handlers to replace the desiccants only when both breathers are thoroughly saturated with moisture.
