This product is intended for use in the return channel on the wall and due to the delicacy of the blade profile, it is placed in places away from the possibility of being hit. It is not recommended to use this type of valve in widths of more than 70 cm or outside the building. Airfoil return valve vanes are fixed and at a 40 degree angle, and when used in long widths, the column is used to create strength in the valve frame. The angle of the vanes is such that, at the same time as reducing the pressure, the visibility into the channel is also minimized.
Installation :
This valve is installed by automatic screws on the edge of the channel and on the wooden frame, so it can be used on walls such as brick, cement, plaster, wood, etc. Airfoil vane return valve can be installed with parallel and opposite valve back dampers.
