R Series Transformer Breathers

‘R’ Series Transformers Breathers are used to keep and check desiccant condition with ease. Manufactured from UV stabilised polycarbonate, and can operate under high mechanical stress.

Made with UV stabilised and shatterproof polycarbonate window, ‘R’ Series Transformers Breather has a transparent, clear body that allows you to check the desiccant condition with ease.

With two-way, low-pressure valves fitted in the Breather base, it ensures that air only enters the breather when there is a negative pressure differential within the equipment.

Additionally, the unit is mounted from a ¾” female pipe thread connection at the top of the breather. It allows for filling and emptying the desiccant inside the breather with minimum effort.

Catering to different requirements, the R series comes in different sizes – R, R1, and R2. The R3 breather is made up of two R1 Breathers, fully saturating one before the other. This model gives handlers more time allowance as they will only need to replace the desiccants when both breathers are thoroughly saturated with moisture.
