Technology

OPTIMIZE VENTILATION.
CUT ENERGY.
LOWER EMISSIONS.


Daikin delivers gas-phase air cleaning through a breakthrough, non-toxic ventilation solution that removes carbon dioxide (CO₂), ozone (O3), and a wide range of volatile organic compounds (VOCs), including formaldehyde.

When paired with ASHRAE 62.1’s Indoor Air Quality Procedure (IAQP), gas-phase air cleaning reduces outside air requirements by up to 80% and cuts HVAC energy use by up to 40%, while still delivering clean, comfortable air to the space. That means clean air, lower operational costs and a optimized carbon footprint.

What Is Gas-Phase
Air Cleaning Technology? 

Gas-phase air cleaning is more than just a filter; it’s a fully integrated solution. Daikin’s system includes:

  • Advanced sorbent filters engineered to selectively capture key indoor air contaminants
  • Optimized air mixing and control integration for precise airflow management
  • Automated regeneration process that controls CO2 in the space by capturing and moving it to the outdoors without manual intervention

The U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) found that Daikin’s Sorbent Air Cleaning offering can reduce cooling energy use by up to 37%.

Why Gas-Phase
Air Cleaning Is Different 

Sorbents have been used for decades in environments like space stations, submarines, odor control systems and hazardous workplaces. But Daikin’s gas-phase air cleaning solution takes this technology further. Our sorbents were developed through cutting-edge     material science in collaboration with national labs, universities and R&D teams.



How It Works:

 

SVT-Adsorption

Scrubbing Mode
(Adsorption) 

During normal operation, gas-phase technology pulls air through sorbent filters. Contaminants – like CO₂, VOCs, and formaldehyde – bind to the sorbent, effectively removing them from the air. The result is clean, healthy indoor air and reduced need to dilute contaminants by ventilating with outdoor air.

Regeneration Mode

To maintain CO2 removal performance, the filters periodically regenerate. This involves gently heating the filters to 130–150°F, causing the sorbent to release trapped CO2, which is then vented outside via the building’s exhaust. Once regenerated, the filters resume capturing pollutants. Other contaminants such as VOCs that are not purged through the regeneration process stay trapped in the filter throughout its useful life of up to 2 years.

The regeneration cycle is fully automated and set during initial system configuration.

What Gas-Phase
Air Cleaning Targets

Gas-phase air cleaning ‘s multi-sorbent technology is designed to capture a wide range of airborne contaminants commonly found in indoor environments, including:

  • Carbon Dioxide (CO₂)
  • Volatile Organic Compounds (VOCs)
  • Formaldehyde
  • Inorganic Compounds
  • Ozone (O3)

SVT-Long-Filter-Life

Safe, Regenerative,
and Efficient 

Sorbent filters offered by Daikin are the first to regenerate at temperatures below 1,000°F, making them safe for continuous indoor use. This low-temperature regeneration allows the filters to retain their efficiency over and over again, reducing replacement needs and increasing system longevity.

Long Filter Life
and Maintenance 

Sorbent filters offered by Daikin deliver reliable performance for up to two years before replacement is needed.

Filter replacement is quick and easy, and replacement filters can be ordered through your Daikin Manufacturer Representative or Daikin Parts Stores.
