HVLS Fans for Airports & Hangars



In a large open space, it is difficult to achieve ideal air distribution. Cold air tends to settle while warm air rises, resulting in stratified layers that tend to stagnate. In addition, it is not uncommon for the temperature difference to result in the formation of cold down-drafts along vertical surfaces. These can cause uncomfortable cold spots in the building.

For these reasons, it is often a good idea to incorporate an air distribution solution, such as large industrial HVLS (high-volume, low-speed) ceiling fans, into the design.


High-Volume, Low-Speed (HVLS) fans are large fans that move a significant amount of air. We intentionally designed our HVLS fan with symmetrical blades that allows for true reversibility during the winter months. The benefit is the fan will effectively de-stratify uneven temperatures that can be in excess of 30 degrees from floor to ceiling and can successfully provide up to 40,000 square feet of destratification coverage.

In the warm months of the year, because of our patent-pending technology, the Z-Tech™ fan blankets a massive area, moving air to create an expansive comfort zone of up to 30% more coverage than our competitors. As a result, an evaporative cooling effect of up to 10 degrees is achieved. You can feel the difference!


Installing a Z-Tech™ HVLS fan will help reduce the utility bills by mixing the air within the facility and creating a more even temperature at floor and ceiling helping a HVAC system cycle less frequently.

GFY® Z-Tech™ fans are specifically designed to:

  • Circulate airflow from one area to another
  • Provide evaporative cooling effect in the summer
  • Warm spaces in the winter using recommended winter rotation
  • Decrease airborne pollutants
  • Save money on heating and cooling costs and HVAC equipment repairs
  • Protect the planes and equipment from humidity


Hangars – Buildings that demonstrate excessive outside air infiltration are especially prone to high energy costs. In the case of hangars, the large doorways, potential inadequate air sealing and insulation, and poor heat distribution all contribute to energy loss.

In the summer, high-volume, low-speed hangar fans provide welcome and cost-effective relief from accumulated heat inside an aircraft hangar. Their ability to move massive amounts of air over and around objects creates a cooling effect of up to 10 degrees. In addition, these fans can help keep aircraft clean by repelling pigeons and other birds that like to roost in hangar rafters.

In cool weather, temperature differentials in a hangar can vary by as much as 30 degrees from floor to ceiling. Conventional heating methods often fall short because the high ceilings in a hangar simply trap large amounts of heated air where it is not needed. At the same time, drafts from hangar doors and other air leaks lead to uncomfortable working conditions for hangar personnel. Hangar fans can help by redistributing heat from near the roof down toward the floor where it is needed most.

Airports – The last thing stressed travelers want or expect is having to endure hot, stuffy air at the airport. Yet, airport terminals can be notoriously difficult to heat and cool efficiently. Large high-volume, low-speed airport fans can greatly improve energy efficiency in these buildings by gently moving large amounts of air throughout the facility — even over and around obstacles such as consoles and support pillars, and through the irregular spaces of concourses and terminals.

Another airport challenge is maintaining air quality. The constant need to open doors combined with the presence of aircraft fumes is an HVAC double whammy that airport fans can help to alleviate.

Maintenance – Overheated workers usually will mean less productive workers. Studies show that in an environment over 77°F, productivity will decrease 2 percent for every increased degree. Go Fan Yourself's Z-Tech™ Fans will provide consistent air movement that is needed to keep airport employees feeling cool and staying productive, to keep those flights safe and on schedule.
