The DFA 127 Inverse enables doors to open securely and reliably, even without a power supply.

Its versatility means it is perfect for providing an automatic opening in a wide range of environments, from busy shopping malls to residential entrances and healthcare facilities. It is compact and reliable with microprocessor technology allowing many additional programmed functions.

Characterised by sophisticated technology, compact design and RECORD’s legendary smoothness of operation, the DFA 127 Inverse is ideal for escape routes and where heat and smoke build up is likely.

When the door drive motor operates to close the door, it simultaneously tensions a spring integrated in the drive housing. The shutting movement uses energy stored in the spring, which, depending on requirements, is also motor-assisted. Even without motor assistance, thanks to ingenious mechanics, optimum power deployment is achieved in the entire door swing area which is necessary to move the door reliably to its end position against, for example, draft resistance.
