Guizhou ventilation duct

Single layer adjustable louver vents are commonly used for suction and supply air in pipelines. They can also be equipped with herringbone gates (multi leaf open control valves) according to actual situations to control air volume or install aluminum alloy filters for matching use. The blades can be divided into two types: horizontal and vertical, and can be flexibly rotated left and right or up and down to control the direction of airflow.
