Automatic revolving doors generally come with 2 to 4 wings, depending on the clients' requirements. The 2 wing revolver is designed for gurneys and large deliveries. The 3 wing works well for wheelchairs, parents with children or people carrying luggage or packages. The automatic revolving doors have all the great advantages that the manual revolving doors boast, which are showed as below.

Energy Efficient

The most attractive feature with automatic revolving doors is that they are always open to clients and at the same time, always closed to the weather, which make the revolving door a significant energy saver.

Prevent Drafts

When employees must stand near the entrance they are continually assaulted by drafts as customers enter and exit the building. This can cause much sick leave and job turnover. A door that is always closed, can't let in drafts.

Keeps From Noise

This would be much more attractive to a serious businesses or businesses which need the quiet situation situated in areas of town where there is a lot of activity. Banks, law firms, libraries, schools, etc. couldn't tolerate the noisy distractions. Revolving doors are always closed even as people are coming in.

Stop From Wind, Snow, Sand, Dust etc.

This is attractive for businesses whether they have opened business in "the windy city" or whether they are situated in the small towns of the flat desert or the seaside, where sand and dust blow freely. Revolving doors will reduce energy and maintenance cost, as well as relieve the eyes of both clients and employees alike.

When revolving doors are automatic they have some additional benefits as following.

Hands Free

Clients and employees carrying children or packages can concentrate on what they are holding rather than juggling them to manipulate the entrance. The disabled can easily enter and exit them.

Customized Controls

The doors can be programmed to correspond to your building traffic, they can be programmed for speed to prevent the doors from spinning too fast, risking injury. 

Detective Sensors

Sensors start the door revolving when a person approaches and stop it when the person exits or when there is an obstruction.

Security

Businesses that require ID cards for employees only, have doors that fit only one person, so no-one can tailgate in , this function will be more workable for the revolving door with 4 wings . Airports, theme parks and other businesses use the revolving door for the exits to prevent people from entering through the common exit doors and thereby avoiding security or entrance fees. Sensors detect objects that have been put or tossed into the door to be pushed through to the secure side of the building.
