【Negative Pressure Structure】This product's fan draws away smoke above and in front of the water curtain. A stainless steel plate beneath the fan creates a negative pressure chamber. The fan boasts infinitely variable speed, with a 9-blade airflow of 443.31 m³/h 【LED Light】Two ultra-thin, high-CRI LED lights on each side minimize shadows and ensure true reproduction of spray colors, with a color rendering index of 92 【Reversible Water Curtain】The innovative removable water curtain provides the most convenient pull-out water change, eliminating the need to open side panels or lift the entire device 【Dual Filtration】As the paint spray passes from the water curtain to the air outlet, it undergoes multiple filtration processes: water flow, filter pads in the water tank, and a metal filter in front of the air outlet 【Dense Water Curtain】The cabinet forms a self-circulating water curtain, drawing paint mist into the water for a clean spraying experience
