The advantages of a glass panel unit are:

• They impart an open "hi-tech" look.
• Easy ADA and cargo throughput.
• Physical barrier instead of a "beep"
• Optomechanical "anti-tailgating".
• Good two-way traffic control

Portal is the name we gave to the third of This Century's Turnstiles!

Aeroturn's Portal principal features are:

• Zero-Maintenance through a minimum of 10,000,000 cycles.

• Compound Barrier Movement unique to Aeroturn!

Panels rotate and translate keeping the edge of the barrier midway along the pas-sageway (like a pocket type) while storing the panels parallel to the passageway (like a saloon door type). This gives the safest and widest passageway with the narrow-est cabinet. Unprecedented ADA compati-bility, particularly with the footrests of wheelchairs and in bi-directional traffic.
