Direct Fired Makeup Air

Direct-fired makeup air units fire a burner directly in the airstream, delivering very high thermal efficiency because nearly all the combustion heat enters the space. They're specified where a building needs large volumes of tempered replacement air and the application allows adequate dilution.

This collection carries replacement controls and components for direct-fired makeup air systems. For complete units, we produce the equipment selection and system design for the project — learn more about makeup air and industrial ventilation, or see Energy Jet unfired makeup air for buildings with significant ceiling stratification.
