The DFA 127 is the powerhouse of automatic swing door operators.
Its versatility means it is perfect for providing an automatic opening in a wide range of environments, from busy shopping malls to healthcare facilities. It is compact and reliable with microprocessor technology allowing many additional programmed functions.
The adjustable spring force of the DFA 127 Full Power enables a range of door sizes from 50kg to 350kg to be used. Spring forces can be quickly and easily adjusted on-site using the adjustment screw. The sophisticated technology enables complex functions to be programmed with ease and optimum power deployment in the entire swing area.
The DFA 127 Full Power microprocessor controls every door movement evaluating the current door position, the door speed and the final position at every instant to precisely calculate the optimum motion. This eliminates any sudden end-stops, jerky braking actions, or creep speed increases.
Safety is also additionally increased by the use of a redundant force limitation option which comes into operation should power to the main operator be lost.
In addition, the operator can be programmed to stop and retract upon encountering an object in the entrance, which makes an ideal automatic swing door operator where elderly or physically impaired patrons utilise the doorway.
