Air domes are pressurized structures, with air blowers constantly inflating the dome. Our domes come with both a main inflation unit and an auxiliary inflation unit that is powered by a natural gas- or propane-powered engine, which automatically starts up when the inflation pressure goes down (in accordance with the International Building Code [IBC 2018] Section 318.104.22.168). The inflation units automatically adjust the pressure of the dome. Our mechanical engineers (licensed in all 50 states) determine the amount of CFM needed in your inflation units to maintain pressure, replace lost air, and provide needed air exchanges in the dome. Inflation units can also include enough CFM to replace air lost through open exit doors. This is required for domes with an occupancy of 50 or more, per IBC 2018 3102.8.3 and ASCE 55-16 C22.214.171.124. Broadwell also offers an advanced air filtration system that cleans and sanitizes the air in your dome.

Heating and Air Conditioning
We can provide natural gas-powered heating and air conditioning units, which can be incorporated into an all-in-one unit with the inflation blowers. Broadwell's domes are the most efficient air domes in the world due to our thicker, stronger fabric and our triple weld manufacturing method, increasing the overall R-value of the dome.
The inflation and HVAC units are located outside of the dome, with ducts going from the units to inside of the dome via ducts connecting to the dome wall, or via underground ducts coming up into the floor of the dome.
