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.

Frequently Asked Questions – Silica Gel Breather
What is a silica gel breather used for?
A silica gel breather is used in transformers to absorb moisture from air entering the conservator tank. It prevents moisture contamination of transformer oil, improving insulation life and transformer performance.
What sizes of silica gel breathers are available?
Silica gel breathers are available in capacities ranging from 0.25 kg to 12 kg, including 250 gm, 500 gm, 1 kg, 2 kg, 5 kg, 6 kg, 8 kg, 10 kg and 12 kg models.
Which type of silica gel is used in transformer breathers?
We use self-indicating silica gel beads that change colour from blue to pink or orange to colourless when saturated, providing a clear visual indication for replacement.
How often should silica gel be replaced or regenerated?
Silica gel should be replaced or regenerated when the colour changes completely. Under normal operating conditions, this is typically every 6 to 12 months, depending on humidity and environmental exposure.
What materials are used in silica gel breathers?
Silica gel breathers are constructed with powder-coated aluminium top and bottom housings, a transparent acrylic or polycarbonate centre chamber, NBR rubber sealing and a polycarbonate oil cup.
Which transformers can use silica gel breathers?
Silica gel breathers are suitable for distribution transformers, power transformers, substations, bus ducts, railways and industrial electrical equipment.
Are custom sizes or OEM branding available?
Yes. We offer custom sizes, OEM branding and bulk manufacturing options. You may also explore our silica gel pouches for additional moisture control solutions.
Do silica gel breathers require maintenance?
Maintenance is minimal. Regular visual inspection of silica gel colour and oil cup condition is sufficient to ensure proper operation.
