High Efficiency, High Volume Capacities
Includes Proprietary Synergy Diffuser Wheel Models
Perfect for Custom and Site-Built Applications


Custom site-built air handlers, multiplex fan arrays, high temperature air circulation, and embedded installation are just a few of the design challenges that Peerless' Plenum and Plug Fan models easily solve.

Hot Air Circulation

Dryers, ovens, auto-claves, and similar process equipment often require consistent, reliable hot air recirculation as part of their design, which are exactly the type of tough applications that our Plug Fans are strategically designed to handle.

Direct Plenum Pressurization

Some of the world’s largest, most complex office buildings receive clean ventilation air from relatively simple air handling systems known as ‘fan arrays’. Our Plenum Fans are just the type of models intended for these arrays, where multiple stacked fans directly pressurize an air plenum, creating and distributing comfortable air throughout the facility.

Best-In-Class Performance

With larger diameter front- and backplates creating a unique diffusing area to smooth out discharge airflow, our Synergy Plenum and Plug Fan models utilize a proprietary diffuser wheel to convert kinetic energy into pressure energy at very high efficiencies and very low noise levels.
