Built-up Systems and Self-Contained Unit Ventilators

Quiet Classroom Comfort and Low Operating Costs

unit ventilatorsFor nearly a century schools have relied on unit ventilators to keep classrooms comfortable. Students learn more readily in a quiet, well-ventilated environment. That is why Herman Nelson invented the unit ventilator in 1918.

Today Daikin remains committed to continuing the Herman Nelson-AAF-McQuay legacy as the industry leader and meeting the changing requirements of schools with the highest quality unit ventilator products available.
