Air Travel Case Study

Portland International Jetport

Portland International Jetport is a public airport two miles west of downtown Portland, Maine, United States. It is owned and operated by the City of Portland. The airport is the busiest in the state, handling more than one-and-a-half million passengers annually.


Airport terminals require a substantial amount of ventilation air to satisfy code requirements for 24/7 operation. The air must be properly cleaned with high-efficiency air filters to not only assure good indoor air quality per code but also protect the HVAC equipment for efficient operation.


Substituted conventional filters with powered minimum MERV 14 final filters. Biotronic filters were selected for use in the two new large custom air handlers. The filters were arranged in a V-bank configuration, which significantly extends the duration of the filter and reduces the labor hours required to maintain these large units.


Reduction in filtration total cost of ownership.
