The innovative electronics in the ASSA ABLOY SW300 automatic swing door operator ensure minimal energy consumption for optimal door performance. It is safe to use for all, despite age and physical ability. In case of an obstruction by a person or object, the obstruction control ensures stop on stall and reverse operation. Furthermore, the ASSA ABLOY SW300 Swing Door Opener is fully compliant with European standards and fire approved, making it ideal for creating and maintaining security, smoke and fire zones. An entrance equipped with a ASSA ABLOY SW300 opener is always accessible due to battery backup. The ASSA ABLOY SW300 also monitors the battery for power and function, and gives an electronic indication if it is not working properly and needs to be replaced.

The opener is truly reliable during all weather conditions as it is not affected by stack pressure and wind load when opening and/ or closing. For a convenient, safe and quick exit, the ASSA ABLOY SW300 can easily be manually opened, despite extended closing torque, due to sensor detection ensuring lowest manual opening force. In addition to the standard version, there is a Double Acting (DA) function with possibility for manual opening in both directions with automatic reset.

Protection class:



ASSA ABLOY SW300’s intelligent locking features are designed for peace of mind. Double doors are precisely controlled to prevent jamming and increase security. The ASSA ABLOY SW300 opener can also sense when the door has not closed completely and will prompt the door to open again and close fully, even under heavy wind load and stack pressure.


The 70 mm slim ASSA ABLOY SW300 swing door requires a minimum of space while providing maximum performance. The door system operates silently despite its capability to handle heavy doors up to 250 kg. ASSA ABLOY SW300 can be retrofitted with existing doors and thereby keeping the overall door system design and environment aesthetically intact.
