SMARTair® Electronic Knob Cylinder

Upgrade existing door cylinders with a SMARTair knob cylinder with integrated RFID reader. Easy to retrofit, in multiple finishes, and compatible with virtual keys in the SMARTair Openow app.

The new SMARTair knob cylinder is a door device improved in every way. Its world-class design is robust and resistant. The knob cylinder comes in more finishes and colours, upgrading aesthetics and functionality in equal measure. Suitable for any door, it quickly upgrades your existing mechanical cylinder to a real-time access-controlled cylinder – without any drilling or wiring at the door.

The new SMARTair knob cylinder is a wireless locking device designed for office and meeting room doors, as well as existing glass, aluminum or wooden doors where installing an escutcheon proves difficult.

Powered by a standard battery, it has an integrated RFID reader with LED (blue/red signal) combined with online or update on card. The device accepts RFID credentials, including HID iCLASS®, MIFARE® Classic and Ultralight, SKIDATA and DESFire®.

A SMARTair knob cylinder is available for almost any type of door, for easy retrofitting. Models are available in half-cylinder, cylinder with thumb turn, double electronic cylinder, double mechanical electronic cylinder and padlock formats. The hardware comes in profiles to fit any global market: European, Scandinavian, ANSI, Australian, and Finnish.

The SMARTair knob cylinder is offered in a range of finishes for any style or design scheme. It is suitable for usage on exterior and narrow profile doors.
The knob cylinder delivers convenience for building users. The cylinder is also compatible with virtual keys stored in the user-friendly SMARTair smartphone app, Openow, and with the TESA SMARTair app for remote opening.
