Single Column Breather


Our new Single Column Breather (SCB) is the economical solution for all your breather needs! Using the same technology as our proven dual column design, this breather efficiently dehydrates the air coming into your transformer then regenerates the desiccant while the transformer is not “inhaling,” thereby keeping moisture out.


  • Sealed/Latching solenoid for improved reliability
  • Aluminum and stainless steel construction for durability
  • Borosilicate glass globe resists weather-related etching
  • Sealed, super bright 10,000 mcd LED indicators on control box provide easy visual indication of breather status, even in direct sunlight
  • Time-based regeneration settings included
  • Standard alarm contacts for remote alerts
  • Adapter plate enables easy upgrade from ARDB2
  • Conduit wiring does not require adapter box
  • All of our breathers ship with an environmentally-friendly and enhanced performance clear silica gel



Our single column breather utilizes vacuum switch technology to sense when the transformer is inhaling, ensuring that moist air is not introduced into the oil. If this interruption occurs, the control firmware “teaches” the breather to shift the next regeneration to an ideal time. A vertical mounted latching solenoid in the breather will not overheat the electronics inside and ensures that the airflow stops when regeneration of the silica is safe.
