Helfer System (Y-Duct Design)
Helfer System (15" Full Round Duct)
- The Helfer duct rocket penetrates the center of the bin to release air into the core
- Fan efficiency is increased by as much as 20%
- Static pressure is lowered
- Drying time is reduced by as much as 50%
- 15" round floor ducts push air up from the floor and out towards the bin walls
All of the systems below come standard with a 48" Helfer duct. Add 24" or 48" extension for all tall bins.
