Air volume damper with gasket is used for adjusting air flow rate and pressure in air handling units, air ducts and similar systems. The width of blade is 108 mm and with the help of the aerodynamic structure of blades the resistance occuring against air flow is reduced to minimum. Blades are driven oppositely by the gear mechanism manufactured from PVC material. This feature simplifies the flow rate control. Maximum impermeability is provided by gaskets on blades. Also flow rate adjustment is made with the metal command handle as OPEN-CLOSE and interval values written on the handle.
