Uses:

The silica gel breather‌ is an air purification device, which is installed at the end of the air inlet of the oil storage cabinet of the transformer and transformer, which can effectively filter the dust and moisture in the air to maintain the cleanliness and electrical performance of the transformer oil.

Features:

1. The clean room uses a fully transparent and lengthened tempered glass tube to extend the filtration time, which is significantly higher than the conventional silica gel breather‌ by 30%.
2. The bottom adopts double-layer transparent tempered glass structure. After the oil cup is refueled, the suction and exhalation of the silica gel breather‌ can be directly observed when the transformer is operating.
3. The red protective cap at the bottom can prevent the silica gel from being contaminated during transportation. (The protective cap is for transport only, the moisture protection cap must be removed when filling the glass with oil)
