During Heating and cooling process of transformer oil Air pressure comming out and going inside the transforemer, This process is called BREATHING of Transformer. Silica Gel Breather helps to avoid entry of humidity and dust inside the transformer oil, humidity is main causes of fluctuation of DIELECTRIC STRENGTH, which is damaging the transformer functionality and out put of current flow. To maintain Humidity Silica Gel Breather plays a very important role in TRANSFORMER.
Silica Gel Breather is made from the finest quality raw material of Orange Silica Gel. We are Silica Gel Breather Supplier and Exporters.

Function of Silica Gel Breather :
The sole function of Silica Gel Breather is to dehydrate (remove moisture) the air & to remove dust particles of the air breathed in by the transformer.
Operation & Working of Silica Gel Breather :
Silica Gel (Air dehydrating) breathers are transparent hollow cylinder tubes which contain chemically pure silicium salt (Silica Gel) with cobalt indicator. This grade of Silica Gel is called as indicating grade of Silica Gel.
The indicating grade of Silica Gel, which is filled in the breather, is hard blue crystals, which has considerable absorption power for moisture. Silica Gel absorbs moisture signaling the saturation degree by changing color as follows.
- Deep Blue Silica Gel completely dry
- Light Blue Silica Gel partly humid. (Absorbed water for about 15% of its weight)
- Pink Silica Gel saturated with moisture. (Absorbed water for about 30 - 40% of its weight)
