Gen 1 to Gen 3 System Upgrades

Are You Using Outdated UFAD Systems and Want to Benefit From The Latest Advances in Comfort, Air Quality & Cost Savings?

Upgrading from older MT1 or other Underfloor Air Distribution Systems can significantly improve your environmental air efficiency while reducing your energy costs.

Upgrading Your UFAD Systems to
MIT3 Can:

  • Reduce energy usage
  • Deliver improved efficiency through “time modulation” tech
  • Improve ventilation efficiency
  • Boost occupant comfort & productivity
  • Offer better architectural options


In 1998, York introduced the first generation Modular Integrated Terminal (MIT-1), designed to provide constant velocity air supply in variable-air-volume UFAD applications. Although York’s first generation MIT design was the best technology available at the time, due to various deficiencies in its controls and mechanics, a high percentage of the active systems placed in operation between 1998 and 2008 have since become inefficient and unreliable. In fact, new technology is the very reason why AirFixture took it upon themselves to develop its own patented system, resulting in the release of the MIT2 in 2004 followed by the most current revision – MIT3.

MIT3 units incorporate AirFixture’s patented “Time Modulation” technology and are provided with a standard 18-month warranty (with extended warranties available at very low cost). Since the introduction of the direct drive time modulation air valve and its simplified and robust design, virtually zero failures have been reported relative to the hundreds of thousands of systems currently in operation worldwide. MIT3 presents a number significant benefits to existing building owners who currently operate MIT1 or other UFAD systems.

Many existing UFAD systems don’t provide consistent temperature control if any at all. Outdated manual controls are stuck or non-functioning. Many older systems do not meet current ASHRAE ventilation standards. Some are noisy and require constant maintenance.

Other manufacturers do not have a robust parts business to support these aging installations – AirFixture’s experts can help you get the most out of your UFAD system.

What our clients say about us

“Recently my firm was working with a high-profile financial services client requiring an Under-Floor Air Distribution (UFAD) solution in One of New York City’s most Premier buildings. Before we were even awarded the project, I knew I had to call AirFixture. Their Unit specification and construction is the top of the line and they are the quietest units in the industry. Their Air Towers remove the need for ductwork and their zoning/controls are some of the simplest I have ever seen. That coupled with the fact that the company leadership contains two of the most senior and knowledgeable leaders in the UFAD industry is simply something the competition cannot match.”
