Product Description

Transformer Moisture Absorber, also known as silica gel breather, is a key protective device installed on the conservator tank of oil‑immersed transformers. It effectively adsorbs moisture, dust and harmful gases from air entering the transformer, preventing insulation oil from emulsification, deterioration and reduced dielectric strength.The device is filled with high‑performance color‑changing silica gel, which visually indicates its saturation state for timely maintenance.

Key Features

• Efficiently absorbs moisture and filters air impurities
• Visible color‑changing silica gel (blue to pink/white) for easy monitoring
• Good air permeability, low resistance, stable breathing performance
• Oil‑proof baffle design to prevent oil splashing and backflow
• Corrosion‑resistant metal or plastic housing, durable for outdoor use
• Simple structure, easy to install, replace and refill
• Suitable for various temperature and weather conditions
• Effectively extends service life of transformer insulation oil
