Aeroseal Success at The Auckland International Airport
Auckland International Airport is the gateway by which the majority of visitors - both Kiwi and international, enter and leave New Zealand. It is the singular, best known location in the whole country.
When Econair Services Limited approached LIMS Aeroseal to ensure airtightness in a key section of the airport’s new terminal, we were thrilled at the opportunity to put our name on it. This case study highlights our involvement in Work Package Two (WP2) ofthe terminal project, showcasing howAeroseal technology delivered exceptional results in sealing ductwork and meeting stringent industry standards.
Project Overview
Client: Econair Services Limited
Reporting to: Josh Brunton (Mechanical Engineer)
Initial Scope: Seal and certify airtightness on three ductwork runs in the Arrivals Hall under construction. The target was to reduce leakage below 50L/s at an operating pressure of 500Pa.
Expanded Scope: Over the course of six engagements, LIMS Aeroseal performed 17 sealing events across various duct sections with tolerances ranging from 171L/s to 55L/s. Every tested section was brought into compliance by project completion on 28 March 2025.

Timeline and Execution
The project began with a purchase order issued on 29 July 2024. While initial engagements were brief one- or two-day affairs, the major push occurred over fifteen consecutive business days starting on 28 February 2025. During this period, our team worked tirelessly to meet expanded scope requirements and ensure airtight compliance across all duct sections.
Challenges and Achievements
The acceptable leakage tolerances ranged widely, from as high as 171L/s down to the stringent target of 55L/s. Using Aeroseal technology, we successfully sealed every duct section to meet or exceed these requirements. This achievement underscores the effectiveness of Aeroseal in tackling even the most demanding projects.
- The ductwork for AHU-T2-16 Service Spine has a measured leakage rate of 57l/s which is below the calculated maximum allowable leakage of 205l/s. This was measured with a test pressure of 503 Pa.
- The ductwork for AHU-T2-16 Plenum has a measured leakage rate of 55l/s which is below the calculated maximum allowable leakage of 58 l/s. This was measured with a test pressure of 500 Pa.
- The ductwork for AHU-T2-16 Plenum has a measured leakage rate of 55l/s which is below the calculated maximum allowable leakage of 58 l/s. This was measured with a test pressure of 500 Pa.
- The ductwork for AHU-T2-16 Plenum has a measured leakage rate of 55l/s which is below the calculated maximum allowable leakage of 58 l/s. This was measured with a test pressure of 500 Pa.
- The ductwork for AHU-T2-81 Immigration has a measured leakage rate of 23l/s which is below the calculated maximum allowable leakage of 35l/s. This was measured with a test pressure of 501 Pa.
- The ductwork for AHU-T2-81 Return has a measured leakage rate of 44 /s which is below the calculated maximum allowable leakage of 119l/s. This was measured with a test pressure of 506 Pa.
Conclusion
Completing WP2 at Auckland International Airport was a milestone for LIMS Aeroseal. Not only did we help Econair Services Limited meet industry standards for ductwork airtightness, but we also demonstrated the scalability and reliability of Aeroseal technology in high-profile projects. With the terminal forecasted for completion in mid-2025, our contribution ensures optimal performance and energy efficiency for years to come.
This project exemplifies how LIMS Aeroseal continues to set benchmarks for innovation and quality in duct sealing solutions. We look forward to future opportunities where we can bring our expertise to similar large-scale ventures!
