Hot-water centrifugal air curtain machine


The centrifugal air curtain is a high-performance air-separation device specifically designed for tall, spacious lobbies, industrial facilities, cold storage rooms, warehouses, and the main entrances of large shopping malls. Compared with conventional cross-flow (horizontal‑flow) air curtains, it employs a forward‑curved, multi‑blade, dual‑inlet centrifugal fan, offering superior advantages such as high static pressure, long airflow reach, and high outlet air velocity. It can create a dense, continuous air barrier across doorways exceeding 4 meters—or even 6 meters—in height, effectively preventing indoor–outdoor air convection while blocking the ingress of dust, insects, and odors, thereby delivering substantial energy savings and enhanced environmental cleanliness.
