When Econair Services Limited needed to ensure peak HVAC performance for the new Arrivals Hall at Auckland International Airport, they turned to LIMS Aeroseal. Our mission was clear: achieve airtightness certification for critical ducting runs in Work Package Two (WP2) using our industry-leading nanotech sealing technology.
What began as a targeted scope to seal three ductwork runs quickly evolved. Thanks to the efficiency of the Aeroseal process, our team—led by Lucas Scott James and Alan Baird—successfully executed 17 sealing and certification events over the course of the project.
During a concentrated 15-day push in February 2025, our technicians worked around the clock to meet rigorous compliance standards across various duct sections, with tolerances ranging from 171L/s down to a highly demanding 55L/s.
We didn’t just meet the targets; we consistently outperformed them. By sealing from the inside out, we achieved the following verified results:
| Duct Section | Target Max Leakage |
| AHU-T2-16 Service Spine | 205 L/s |
| AHU-T2-16 Plenum | 58 L/s |
| AHU-T2-81 Immigration | 35 L/s |
| AHU-T2-81 Return | 119 L/s |
Traditional sealing methods often struggle with the complex geometries and high-pressure requirements of international airport infrastructure. The Aeroseal nanotech compound bridges gaps that manual sealing simply cannot reach, ensuring that every cubic meter of air goes exactly where it’s intended.
This project underscores our commitment to providing commercial HVAC solutions that are not only effective but also certified to the highest industry standards.
