Large Transformer Breathers

The transformer breathers are designed to provide optimal moisture protection for large-capacity tanks. Their sturdy construction allows these breathers to be mounted through a flange or pipe thread connection. Equipped with two-way pressure valves in their base plate, the breathers ensure that air enters only when there is a negative differential air pressure.

The desiccant container in these breathers is made of mild steel and is removable, while they are protected with a phosphate and powder coat finish. A shatter-proof and UV-stabilized polycarbonate window provides clear visibility of the orange silica gel, which changes colour from orange to green, visually indicating the need for replacement. Four metal tie rods with threaded nuts clamp the breather between the top and bottom endplates.

Replacing the indicating silica gel is easy – release the threaded nuts. In addition, all threads in these breathers conform to BS21 and ISO7-1 standards. The size V, W, and X transformer breathers have a ¾” female pipe thread, while the size Y and Z transformer breathers have a 1” female pipe thread.
