Transformer Breathers

Regenerable in service — heat for two hours and refit

Any oil-filled or vented plant breathes as it heats and cools, and every breath pulls humid air across the oil. A breather intercepts that air. The indicating gel is visible through the body, so a maintenance walk-round is enough to judge condition, and the charge can be regenerated at about 150 °C for two hours rather than replaced.

Key features

  • Clear view bodies in polycarbonate or transparent acrylic with aluminium caps
  • Aluminium bodies with inspection window and die-cast caps
  • Thread and flange connection options
  • Crystal 4–6 mm and 6–8 mm; beads 1–2 mm and 2–4 mm
  • Indicating blue or orange charge

Why customers specify it

  • Condition assessed visually during routine inspection
  • Charge regenerates at ~150 °C for ~2 hours — low running cost
  • One design covers transformers, hydraulics, gearboxes and fuel storage
