Why we stock the KDK.
The KDK 3509UA is a 90cm air curtain with a long 3.5-metre projection and high air velocity (up to ~11 m/s) — a strong barrier for tall single doorways. Sirocco fan, durable resin housing, 2-speed control. Air curtains mount above the doorway and are hardwired — SparkFlow's appropriately qualified electricians supply, install and wire it (shopfronts, F&B, cold rooms, loading bays), with installation included in the quote rather than charged as an add-on. WhatsApp us your door width and height for a fixed supply + install price.
