Product Lines
Roof-Mounted Fans
Greenheck's roof-mounted fan product line covers centrifugal upblast, downblast, inline, and utility fan configurations for commercial and industrial rooftop exhaust. The line is specified for general building exhaust, laboratory fume exhaust, kitchen exhaust, and industrial process ventilation where the fan must mount at the roof deck. It spans light commercial through large industrial installations.
Energy Recovery Ventilators
Greenheck's energy recovery ventilator (ERV) line provides fresh outdoor air in compliance with ASHRAE Standard 62 while recovering energy from the exhaust air stream. ERV units transfer heat and moisture between incoming and outgoing airstreams, reducing the conditioning load on the HVAC system. The line is specified for schools, healthcare facilities, and offices where code-required fresh air ventilation would otherwise significantly increase energy use.
Kitchen Ventilation Systems
Greenheck has manufactured commercial kitchen ventilation components and systems since 1975. The line covers Type I and Type II exhaust hoods and make-up air supply hoods for restaurants and institutional kitchens. It is specified for commercial kitchen projects where listed hood performance and compliant makeup air balance are required.
Dampers
Greenheck's damper line covers UL-listed fire and smoke dampers for life safety applications. It also includes control dampers for airflow regulation, isolation dampers, balancing dampers, and relief dampers for commercial and industrial HVAC systems. The line is specified for commercial HVAC systems where rated fire separation or precise airflow control is required.
Louvers
Greenheck's louver line includes conventional, wind-driven rain-resistant, hurricane-rated, and operable louvers for commercial building facade and equipment screen applications, controlling rain infiltration while maintaining required free area for ventilation.
Why Contractors Specify Greenheck
Greenheck has been producing commercial ventilation equipment for over 75 years from its Schofield, Wisconsin headquarters. The product line covers the full scope of commercial air movement — fans, energy recovery, kitchen ventilation, dampers, and louvers — within a single manufacturer catalog. CAPS and eCAPS product selection software provides performance data, submittal documentation, and Revit output. Greenheck dampers carry UL listings for fire and smoke applications, and the kitchen ventilation line has been in production since 1975.
Frequently Asked Questions

What's the difference between Greenheck fire dampers and smoke dampers?
Greenheck fire dampers are UL listed devices installed in fire-rated assemblies to prevent the passage of fire through a duct penetration. Smoke dampers are UL listed devices that close in response to a smoke detection signal to limit smoke spread through ductwork. The specific required listing depends on the building's fire code and the damper's location in the HVAC system.

It is specified for general building exhaust, laboratory fume exhaust, kitchen exhaust, and industrial process ventilation. The line spans light commercial through large industrial installations.
Are Greenheck energy recovery ventilators compatible with existing HVAC systems?
Greenheck energy recovery ventilators are designed for integration into commercial HVAC systems that require outdoor air ventilation. Compatibility depends on the ductwork configuration, design CFM, and controls interface.
What Greenheck product is right for a commercial restaurant kitchen exhaust application?
For commercial restaurant kitchen exhaust, Greenheck's kitchen ventilation line covers Type I hoods for grease-laden cooking equipment and Type II hoods for heat and moisture removal. The specific hood type and matched makeup air unit depend on the cooking equipment's heat output, cooking processes, and local health department requirements.
