Econair Services Limited approached LIMS Aeroseal to seal and certify three runs of ducting in WP2 (Work Package Two) at the Auckland International Airport. We were able to help our customer attain satisfactory airtightness on all counts due to the innovative nature of the Aeroseal nanotech compound and applicators. LIMS Aeroseal performed seventeen seals/certifications at the Auckland International Airport.

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.
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.
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.
