Advanced and scalable CO₂ capture for industrial decarbonization

Dair's innovative Direct Air Capture process is more performant, more scalable, and cheaper than existing technologies

Direct Air Capture (DAC) has the highest carbon removal potential

But the DAC industry has a delivery problem due to unscalable process design

That's the problem Dair is built to fix.

Dair’s process built different from the inside out

Process Innovation
Concentration Swing Adsorption (CSA) works with multiple commercial off-the-shelf sorbents. No proprietary material dependency, no supply chain lock-in.
Energy Efficient
~3x lower energy than conventional DAC systems. CSA operates at low temperature using available industrial waste heat.
Low CapEx
Eliminating the vacuum pump and high-heat equipment removes the most capital-intensive components in conventional DAC.
Modular Units
Factory-manufactured units designed for replication. Deploy one or deploy a thousand, no bespoke engineering per site.
Scalable
Modular “scale-out” approach reduces scale-up risk. Replicating proven units enables faster, more reliable commercial deployment.
Water Positive
Dair’s CSA process captures water from air as a secondary output alongside CO₂, every unit produces water while removing carbon.

A cleaner and cheaper path to CO₂

Our Concentration Swing Adsorption (CSA) system uses mild/waste heat and near-ambient pressure, producing CO₂ at up to 3-5x lower energy

CSA outperforms every TVSA system

Temperature Vacuum Swing Adsorption (TVSA) powers today’s DAC. CSA delivers lower cost, faster scale, and simpler systems.
3-5x
lower cost per ton
30-45° C
less temperature required
3-5x
faster scale up through modular units
Zero
dependency on new material development

Modular by design. Scalable by default.

Meets the gigaton climate model.
