Warm air curtains
TL-3 / TL-3 EC
The TL-3 door air curtain creates an effective air barrier in entrance areas and reliably prevents cold air, draughts, dust and insects from entering. It is ideal for shops, industrial halls, offices and public buildings – anywhere where doors are regularly open or remain open for long periods of time.
