3 wing and 4 wing automatic revolving doors (TAR300 or TAR600 from TSTC) dominate the market primarily because they strike an optimal balance across traffic efficiency, airtightness & energy saving, safety, structural stability, cost and maintenance. 2 wing doors (TAR200 from TSTC)are mainly used for high-end scenarios with narrow entrances, while 5 wing or 6 wing doors are rarely adopted due to poor cost performance.
1. Why 3 wing & 4 wing Designs Prevail Over Other Types ?
Two wing doors. Offer wider passages for luggage and wheelchairs, yet feature poor airtightness and energy efficiency with higher costs. They are mostly installed in luxury hotels and landmark buildings, not mainstream choices.
Three wing doors. Deliver the best overall balance among all indicators with the highest cost performance, suitable for 90% of commercial and office buildings.
Four wing doors.Boast superior traffic capacity. Ideal for high-traffic venues such as airports, railway stations and large shopping malls, they also provide excellent airtightness and a compact structure.
Five wing or six wing doors. Have overly narrow passages that easily cause congestion. They come with high costs and complicated maintenance, so they are barely used in civil buildings.
2. Three Wing Revolving Doors: Universal Choice with Well-Balanced Performance.
2-1. Core Features
▪ Structure. Three door panels arranged at 120° to one another with a central load-bearing shaft, featuring a simple and sturdy structure.
▪ Traffic Capacity. Approximately 12 people per minute in each direction for continuous two-way passage, fitting medium to high pedestrian flow.
▪ Airtightness. Form two air curtains to effectively block wind, dust, heat and noise, reducing heat and cold loss by around 70% compared with swing doors.
▪ Safety Configuration. Equipped with anti-pinch sealing strips, infrared/microwave sensors, emergency stop function, and can be pushed manually in case of power failure.
▪ Standard Size. Common diameters range from 2.4m to 3.6m, compatible with most building entrances.
2-2. Advantages
▪ Outstanding cost performance. Moderate price, simple maintenance and low failure rate.
▪ User-friendly passage. Passage width ranges from 1.2m to 1.8m, ensuring smooth access for pedestrians, luggage and wheelchairs.
▪ Remarkable energy saving. Air exchange volume is over 8 times lower than that of swing doors, cutting long-term energy costs.
▪ Elegant appearance. Timeless design matches the style of hotels, office buildings and shopping malls.
3. Four Wing Revolving Doors: Top Choice for High Traffic & Maximum Efficiency .
3-1. Core Features
▪ Structure. Four door panels arranged at 90° to one another with a compact symmetrical layout and the best airtight performance.
▪ Traffic Capacity. Around 16 people per minute in each direction, about 35% higher than 3-wing doors to avoid congestion during peak hours.
▪ Airtightness. Create three air curtains, delivering the best performance in wind resistance, dust prevention, heat insulation and sound insulation.
▪ Safety Configuration. Fitted with multiple sensors, anti-pinch and anti-collision devices, speed regulation, emergency stop and fire linkage systems.
▪ Standard Size. Available in diameters from 2.4m to 4.0m, perfect for large entrances and high-traffic buildings.
3-2. Advantages
▪ Highest traffic efficiency: The optimal option for venues with large pedestrian flow including airports, railway stations and commercial complexes.
▪ Superior energy efficiency: Excellent air isolation minimizes indoor temperature loss, ideal for buildings with high air conditioning and heating consumption.
▪ Space-saving design: More compact footprint under the same diameter for a neat entrance layout.
▪ High durability: Frames made of high-strength aluminum alloy and stainless steel can resist Grade 8 winds with a service life of over 15 years.
4. Selection Guide: 3 Wing vs 4 Wing Doors ?
▪ Choose 3-wing doors. For regular office buildings, hotels and medium-sized shopping malls; ideal for general budgets and comprehensive performance requirements.
▪ Choose 4-wing doors. For airports, railway stations, large commercial complexes and hospitals; recommended for high pedestrian flow and strict requirements on energy efficiency and passage capacity.
5. Summary
Thanks to the perfect balance of traffic efficiency, energy saving, safety and cost, 3 wing and 4 wing automatic revolving doors have become mainstream products. 3 wing doors are versatile and cost-effective, while 4 wing doors excel in efficiency and airtightness, fully meeting the core demands of modern building entrances.
