Annexair is a privately held North American company established in 1998. We are focused exclusively on designing and manufacturing high-quality, energy-efficient air handling systems. The majority of our product lines incorporate a variety of advanced energy recovery technologies which are designed for commercial, institutional and industrial applications.

Relying on our team of creative and qualified employees who are involved in everything from the design to the manufacturing of our products, Annexair continually strives to exceed customer expectations in terms of the quality and performance of our units. With 99% of our business sales performed in the United States, totalling 6,000 installed systems, we have built our reputation on innovation and customer satisfaction; we are experts in what we master.
Starting from a standard Energy Recovery Ventilator equipped only with a heat wheel and two fans, we have the ability to add any type of cooling or heating device and integrate the latest technologies of air-cooled condensers or water-source heat pump systems you may require. Our capacity range varies from 2,000 CFM to 80,000 CFM and can be combined with a condensing unit that provides between 10 to 200 tons of cooling.
Our elite sales team can quickly and effectively supply you with all the plans, performance documents, specifications you require and assist you every step of the way.
