American-built ventilation since 1965. Tempered air, engineered to fit. Nearly six decades of make-up air expertise.

RuppAir (Rupp Air Management Systems) has been manufacturing tempered make-up air units and ventilation products since 1965, building nearly six decades of expertise into every unit. Application-first by design, RuppAir engineers heating, cooling, and ventilation systems that integrate seamlessly into a facility — whether that's warehouse heating, ventilation for a welding shop, or a fully integrated system for a paint booth. Their lineup spans direct-fired, indirect-fired, and electric make-up air units in horizontal or vertical configurations, packaged rooftop HVAC units with modulating refrigeration and humidity control, a full line of axial and centrifugal exhaust fans for roof, wall, ceiling, and inline mounting, HVLS fans for large-space destratification, and factory-built ductwork including listed grease duct, chimney, and gas vent. Every RuppAir unit is built to last up to 25 years with backward-compatible parts, backed by CASLink cloud-based remote monitoring and a nationwide factory service team. Whether you're tempering make-up air for a manufacturing plant, conditioning a rooftop for a hospital or hotel, or ventilating a commercial kitchen, CES is proud to represent RuppAir across the region, with the technical expertise to help you select, specify, and support the right ventilation solution for every project.
