Direct Drive Ventilation Fan Upgrade
GE’s Direct Drive Ventilation Fans eliminate belts and tensioning maintenance, which can cause over-tensioning, overloaded bearings and fan failure. These direct drive fans are designed to replace the current fans with limited disruption – and are a drop-in replacement upgrade for belt-driven fans for GE packages.

How we get you there

- Grease fittings are located outside of the fan assembly for easy access when lubricating the fan shaft bearings and the motor bearings.
- Air vents were added to the fan casing to utilize ambient air to maintain adequate motor cooling.
