Silica Gel Breather — 0.25kg to 12kg
Seyon Enterprises manufactures high-performance industrial silica gel breathers designed to protect transformer oil from moisture contamination. Available in capacities ranging from 0.25 kg to 12 kg, our breathers are engineered for long service life, reliable moisture absorption, and clear visual indication of silica gel condition.
Each breather is built using premium-grade self-indicating silica gel beads for accurate moisture monitoring, combined with powder-coated aluminium top and bottom housings for superior durability. The transparent centre chamber (Acrylic or Polycarbonate) allows maintenance teams to visually inspect the silica gel without dismantling the unit, making it ideal for distribution and power transformer installations.
Our breathers are widely used by utilities, transformer OEMs, railways, substations, bus ducts and industrial plants across India. They are designed to handle fluctuating environmental conditions while ensuring efficient moisture control and smooth transformer breathing cycles.
