What Is a Pan Diffuser? Specs and How to Specify One
A pan diffuser uses a shallow pan-shaped face to spread supply air in a wide, gentle pattern, suited to lower ceiling heights and lower air volumes. Specs, applications, and how to specify one.
A pan diffuser is an HVAC air terminal with a shallow, pan-shaped face that spreads supply air in a wide, gentle pattern close to the ceiling, suited to lower air volumes and lower ceiling heights than a cone-style diffuser typically handles. Goodwind manufactures the Pan Diffuser in aluminum, with powder-coated, anodized, or custom color finishes, matching the material and finish options used across its wider diffuser range.
Pan Diffuser Specifications
| Spec | Detail |
|---|---|
| Material | Aluminum |
| Finish | Powder coated, anodized, or custom colors |
| Mounting | Ceiling, typically integrated into a suspended ceiling grid |
| Applications | Low-height rooms and lower-volume supply air applications |
Pan Diffuser vs. Plaque Diffuser
Both are flat, low-profile ceiling diffusers, but they solve different problems. A plaque diffuser is chosen for its minimal, no-visible-pattern appearance. A pan diffuser's shallow pan shape is chosen for how it spreads air — a wide, gentle pattern that works well in rooms with lower ceilings, where a stronger cone-style throw could create noticeable drafts at head height.
How to Specify a Pan Diffuser
For MEP Consultants at the Design Stage
Specify a pan diffuser where ceiling height is limited and a wide, gentle air spread is preferred over a directed cone throw. Confirm the airflow volume suits the diffuser's pattern, since pan diffusers are generally matched to lower-volume applications rather than high air-change spaces.
For Contractors at Procurement Stage
Confirm finish and ceiling grid module size against the drawing before ordering, and double-check the schedule calls for a pan diffuser specifically rather than a plaque or square diffuser, since all three can look similar at a glance from below.
FAQ
What is a pan diffuser used for?
It's used in lower-ceiling rooms or lower air-volume applications where a wide, gentle air spread is preferred over a directed throw.
How is it different from a plaque diffuser?
A plaque diffuser is chosen for its minimal appearance. A pan diffuser's shallow pan shape is chosen for its gentle, wide airflow pattern.
Does it fit standard ceiling grids?
Yes, it's typically sized to match standard suspended ceiling grid modules.
What material is it made from?
Aluminum, with powder-coated, anodized, or custom color finishes.
