    The blade can be adjusted to any angle between 0° and 180°. Different angles result in different air delivery distances and diffusion angles. 
    The blade is connected to the outer frame using a special rivet shaft, ensuring that the blade remains firm at any angle while allowing for flexible and convenient adjustment. 
    The neck is designed with four fasteners, allowing for direct connection to a pre-installed air volume control switch or mounting frame using bolts, making installation faster and easier. 
    The blade is designed in an airfoil shape, offering advantages such as low wind resistance and low noise. 
    Made of aluminum profile, with an oxidized surface. Electrostatic spraying can also be applied to meet decorative requirements. 
    Can be used as a return air vent. 
    Optional accessories: G1 air volume control switch, G3 air guide plate. 
    Face dimensions = Neck dimensions + 36
