What are the functions of automatic door closers?

1.Damping and buffering function - generates damping and buffering when the door is quickly opened to a certain position, and the damping and buffering force and range can be adjusted according to usage requirements; This function is used to prevent the door or lock from colliding with the wall when forcefully opening the door quickly, or to prevent people from losing weight and tilting forward and falling to the ground during emergency evacuation.

2. Delayed slow door closing - The door closes slowly and uniformly from the maximum position of the door opening, and can be adjusted infinitely according to requirements. Suitable for frequent and crowded places, especially hospitals, with doors and passages for the elderly, children, and people with disabilities.

3. Adjustable closing force - can be installed on doors with a wide range of weight and width, as well as in places with high closing resistance due to environmental reasons. Random and stepless adjustment can achieve satisfactory closing force, especially when used in coastal cities, vehicles and ships where the resistance to closing the door (force on the door) often changes due to wind influence.

4. Temporary closing performance of damping reset function (vertical door closer) - When opening at any angle, closing the speed control valve should temporarily suspend the damping reset function.

5. Safe and fast super damping closing performance (vertical door closer) - When sudden external force is applied during the closing process at any angle, it should be able to close safely and quickly.
