What Is a Double Skin Eyeball Type Jet Nozzle? Specs and How to Specify One
A double skin eyeball type jet nozzle has a movable outer shroud that swivels like an eyeball, letting the throw direction be adjusted after installation. Specs, applications, and how to specify one.
A double skin eyeball type jet nozzle is a jet diffuser variant built with a movable outer shroud that swivels within a fixed outer shell, letting the throw direction be aimed and re-aimed after installation, unlike a fixed single skin spot type. Goodwind manufactures the Double Skin Eyeball Type Jet Nozzle (model GT-EB) in extruded aluminum with a durable coating, using the same long-throw principle as its general jet diffuser range.

What "Double Skin" and "Eyeball" Mean
"Double skin" refers to the two-part construction — a fixed outer shell plus an inner shroud that moves independently, the way a ball-and-socket joint does. "Eyeball" describes how that inner shroud swivels within the outer housing, similar to an eyeball rotating in its socket, letting the installer or occupant redirect the airflow target without repositioning the whole unit.
How to Specify a Double Skin Eyeball Jet Nozzle
For MEP Consultants at the Design Stage
Specify this nozzle type where the target zone may need to change after installation — seasonal occupancy shifts, reconfigurable spaces, or applications where exact aim can't be finalized until commissioning. Where the target is fixed and known, the simpler single skin spot type is the more economical choice.
For Contractors at Procurement Stage
Confirm mounting method and neck size against the drawing before ordering. Since the swivel mechanism is a moving part, check the specified range of motion matches what the design actually needs before installation.
FAQ
What is a double skin eyeball jet nozzle used for?
It's used for long-throw air distribution where the target zone needs to be adjustable after installation, in large spaces like stadiums, airports, and exhibition halls.
What does "eyeball" mean in this context?
It describes the swivel action of the inner shroud within the outer shell, similar to how an eyeball rotates in its socket, allowing the throw direction to be redirected.
Is this more expensive than a fixed jet nozzle?
The adjustable double-skin construction is a more complex mechanism than a fixed single-skin design, so it's the choice when adjustability is actually needed rather than a default.
What material is it made from?
Extruded aluminum with a durable coating.
