3-Leaf Revolving Air Lock

Revolving air lock doors are typically the primary egress for pedestrian traffic into and out of the dome. These are designed to handle the pressure differential between the exterior and the interior of the dome. Theses doors are made from high-grade, anti-corrosive aluminum. 
Dimensions: 96"(W) x 84"(L) x 83"(T)

ADA-Compliant Personnel Air Lock

Personnel air lock (PAL) doors allow for wheelchairs and small cargo to pass into the dome, while maintaining the air seal.. Most often these doors are included in a tandem combination unit with the revolving door, since IBC (2018) 1010.1.4.1 requires every revolving door to have a swinging door within 10 feet of it on the same wall. 
Dimensions: 70"(W) x 84"(L) x 83"(T)

How Many Exit Doors Do You Need?

The amount of exit doors you need is primarily a function of your occupancy. IBC (2018) 1005.3.2 states, "The capacity, in inches, of means of egress components other than stairways shall be calculated by multiplying the occupant load served by such component by a means of egress capacity factor of 0.2 inch (5.1 mm) per occupant." Thus, your occupancy is multiplied by 0.2 inches, and this number helps the architect determine how many exit doors are required by code (our exit doors have a clear width opening of 43"). Note that your local AHJ may require a different amount, as they have the final say on matters related to fire codes and life safety codes. This is why pre-approving the dome layout--including number and location of exit doors--with your local fire marshal is an important step early on in the dome engineering process.
