Plug Fan
Plug fans move air without a scroll housing, so the wheel and drive install directly into a plenum, or duct run where a conventional centrifugal fan will not physically fit. We represent plug fan lines from Hartzell, Cincinnati Fan, IAP, and Daniels Fans, matched to your static pressure, temperature, and material requirements.
- CFM: capacities up to 145,000 CFM
- Static Pressure: 40” WG
- Temp Range: Up to 900°F (higher with specialized materials)

How Do Plug Fans Save Space in Air Handling Units?
Adding airflow capacity to an existing air handler usually means there is no room left for a scroll housing, an inlet box, or a discharge transition. Plug fans install directly into the plenum or duct run, which removes the housing footprint and keeps the fan inside the existing cabinet envelope.Common applications include:
- Cleanroom ventilation where precise airflow control is critical
- Drying systems and process air handling in industrial facilities
- Dust collection and high temperature operations
Why Source Plug Fans From JEPCO?
Four represented fan lines mean selection starts with your duct geometry and process conditions instead of a single manufacturer catalog. We have represented industrial air movement manufacturers across California and Western and Southern Nevada since 1969.
- 55+ years in business: application history spanning California and Nevada industry
- Four represented manufacturers: cross compare models before committing to one line
- Factory engineering access: fan curve review and system design consultation available
Frequently Asked Questions
What is the difference between a plug fan and a housed centrifugal fan?
A plug fan has no scroll housing and mounts directly into a plenum or duct, while a housed fan requires its own casing plus inlet and discharge transitions.
Can plug fans handle high temperature process air?
Represented models operate to 900°F, with higher ratings available when specialized materials are specified.
Which plug fan wheel type fits my system?
Backward inclined wheels suit clean air at higher static pressure, forward curved wheels suit high volume at lower pressure, and radial wheels are used where the airstream carries particulate.
What materials are available for corrosive or washdown environments?
Wheels and panels are offered in aluminum, carbon steel, and stainless steel depending on the manufacturer and model selected.
