System Overview

Cross-Flow Air Curtain B series 13m/s is built for entrances that need a stronger air barrier than basic doorway ventilation.

Operating an open-door policy often introduces operational challenges, including conditioned air loss, ambient heat infiltration, and the entry of flying insects and airborne dust. The B Series Cross-Flow Air Curtain (13m/s) provides a reliable solution. By creating a powerful yet invisible 13m/s air barrier, it effectively isolates indoor and outdoor environments without obstructing traffic. This mature commercial solution maintains a stable indoor climate and a clean environment while ensuring a seamless, welcoming experience for customers and pedestrians

Core Engineering Features

Built for stronger commercial doorway separation, B series combines 13m/s-class airflow, practical sizes and stable operation.
