The balanced door, colloquially known as the "door that opens with a finger", is widely used as the main entrance of buildings facing outdoors. When there is strong wind outside, ordinary doors require a lot of force to open due to the need to resist the wind. However, the balanced door, featuring a physical door shaft, utilizes the pressure difference generated by the wind on the door. A hidden sliding door shaft balance arm is installed between the door and the door frame. Based on the principle of leverage, the pressure difference between the inside and outside generated by the wind can be used to open the door with little force in strong wind conditions. When closing, the balanced door hardware ensures a smooth operation. The balanced door consists of a door panel, a door frame, a shaft assembly, fasteners, a balance arm, guide rails, locks, etc. Utilizing the principle of wind pressure, it can be easily opened under both positive and negative wind pressures. When the door leaf is opened and closed, the pressure on the inside and outside of the door leaf can be effectively released. It meets the required height and width for passage in building spaces, greatly enhancing the comfort of door leaf opening and closing, while also being safer than traditional floor-spring doors.
The electric balance door not only possesses the relevant characteristics of manual balance doors, but also can be matched with various electronic devices (such as probes, access control systems, door openers, etc.) to achieve automated opening, making it suitable for special places such as disabled access routes.
It meets the national evacuation door specifications and can be installed independently as a building entrance, or installed as a side door in conjunction with other door types.
Scope of application:
- In public places with large pedestrian flow, such as venues and the outer doors of shopping malls, emergency situations can be quickly evacuated.
- For buildings with wind tunnel effects, due to the aerodynamic design of the balance door, it slides and opens in a balanced manner, allowing ordinary people to easily open it with just one finger.
-AD Disabled access, allowing wheelchair users to easily pass through.
-Resistant to Category 11 typhoons, suitable for areas with frequent typhoons and snowstorms
- Airtight and energy-saving, with adjustable sealing strips to reduce internal heat loss.
- Standard outdoor door, best used for door openings with a height of up to 4 meters and a width of up to 1.2 meters.
-An outdoor door with an oversized design is required, with a height within 5 meters and a width within 1.5 meters.
Product Features:
- Meet the design appearance and dimensional requirements, and enhance the overall appearance grade of the building
- Opening the door with the help of wind power reduces the resistance caused by wind pressure and the self-weight of the door; the stronger the wind, the less force is required to open the door, meeting the needs of all users
- The structure is safe and reliable, and complies with the specifications for evacuation doors
- Excellent material
The pivot arm and the fulcrum of the door utilize self-adjusting ball bearings, ensuring low noise and stable operation of the door. The main shaft is made of high-quality alloy seamless steel tube, providing stronger load-bearing capacity.
The rotating shaft arm is made of high-quality stainless steel, providing higher strength and more stable performance
- The door body rotates around the pivot point, saving space and maximizing the peripheral door-opening space; the door body is positioned at 90°
- The main shaft and the door body rotate synchronously, the positioning shaft of the door body moves laterally along the guide rail slot of the chassis, and the concealed door-closing device automatically resets, ensuring smooth and stable operation of the balanced door
- All rotating and door-closing devices are installed in a concealed manner, meeting the aesthetic requirements of the building.
