These units are filled with Envirogel Orange to Green colour changing silica gel which visually show when the unit needs replacing or refilling. Units can also be supplied with thread adaptors and different fill materials if required.
The 'R' Series Transformer Breathers are manufactured from UV stabilised polycarbonate and are available in three different sizes. 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 pressure 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.
High performance plastic construction.
