Superflo Bearing

The Superflo Bearing System represents a mechanical advancement in sleeve bearing systems, featuring a permanently lubricated spinning mechanism for Delta fans. The Superflo system includes an anti-gravity oil pump that re-circulates and recycles the oil in a sealed chamber with dual labyrinth seals. Superflo fans can be used in many of the Delta fan series*.

The Superflo bearing system:

  • Prevents oil leakage
  • Greatly prolongs the life of any fan
  • Runs longer than standard fans

*In the Delta fan naming system, the second digit “U” signifies a Superflo fan.

The Superflo AUB Series fan L10 life is guaranteed for 50,000 hrs @ 40
compared to regular sleeve bearing L10 life of 30,000 hrs @40
