Greenheck QEI Upblast roof fan
In plain English
What it does
A fan moves air. In an electrical installation it can supply cooler air, exhaust warm air or support another planned ventilation duty.
A simple example
In a switchroom, an exhaust fan can remove warm air produced by switchgear and other equipment.
What the drawings help you do
Use the selected manufacturer's drawings to check the equipment's size, mounting points and cable connections. The layout helps you plan where it fits and how it can be reached for maintenance. An illustrative 3D preview does not establish product dimensions or required clearances.

How to read it
- QEI Upblast has its own geometry; the inline QEI envelope does not include the complete roof-mounted assembly.
- A shared QEI family name does not make an inline fan interchangeable with the upblast configuration.
Information to show or reference
- Select the upblast size and arrangement.
- Coordinate curb connections and discharge clearances.
- Reserve belt and motor service access.
A distinction that matters
A shared QEI family name does not make an inline fan interchangeable with the upblast configuration.
