Reduce air flow resistance to optimize fan performance and protects fan from rain.
Our application specialists are ready to help!
No-Loss Stackheads eliminate the back pressure that causes fan resistance while keeping rain out of the fan.
The Stackhead creates a straight shot outside for optimal fan performance – no more twists and turns – and consists of an inside duct and larger outer duct
This design allows the air to exhaust while keeping rain water outside of the inner duct. The rain water falls into the larger duct, drains down the side of the no-loss stack and discharges at the bottom.
