Revolving Door Air Shower
Product Overview
A revolving door air shower replaces hinged doors with a four-leaf revolving door. Personnel push through and step out one segment later; at every angle at least one leaf blocks the passage, so there is no instant at which both sides are open — the airlock is guaranteed by geometry rather than by an interlock circuit.
It suits entrances with continuous foot traffic where queuing is unwelcome. The rotation itself provides the shower period, so nobody has to stand and wait for a door to release, and the flow of people is smoother than with hinged doors.

Detailed Description
Structure instead of interlock
A conventional air shower relies on an electrical interlock to keep both doors from opening together; if that interlock fails or is bypassed, the airlock is gone. A revolving door turns the problem into a geometric one: whatever angle the four-leaf door sits at, at least one leaf lies across the passage, so a straight path physically cannot exist. The trade-offs are that throughput is limited by rotation speed, and that bulky material cannot pass — the sector-shaped space will not take a pallet or a trolley. Entrances that also handle goods need a separate cargo shower tunnel.Selection References
