Nortek Knockdown Unit


DMR is proud to represent products from Nortek Air Solutions (Nortek), including Temtrol, Ventrol, and Huntair, brands that have perfected the design of knockdown units.

Energy Efficiency. Low Sound Levels. Superior Indoor Air Quality (IAQ).

Nortek’s custom flexibility and application expertise provides a wide variety of solutions for replacement and retrofit applications. Whether you need to replace an aging air handler or fan, require a unique configuration or shorter footprint on a retrofit project, or face access and installation challenges, together, DMR and Nortek’s high-performance solutions offer energy efficiency, low sound levels, and superior indoor air quality (IAQ).

If your replacement or retrofit project is facing space and access limitations as well as constraints on installation time and cost, Nortek’s knockdown air handler products offer a best-in-class solution. Knockdown construction means the unit is specifically designed and manufactured to fit through your field opening limitations and weight constraints. The result — faster field installation of a high-quality, site-built air handler.
