The AIR CURTAIN ceiling fan heater silently beams down heat from above. This unique model is ideal for rooms where wall space is limited. In bathrooms, the AIR CURTAIN can be installed just outside the shower or bathtub. With its ceiling-recessed casing, the AIR CURTAIN is an excellent way to provide discreet air circulation. The result: uniform heating and air movement, and reduction in mirror and window fog. By adding a wall timer, you can use it on demand.
