DA - Venkonair

Multiple leaf air volume control damper for installation in square or rectangular air ducts. The frame is made by galvanized sheet steel. With simultaneously, opposite rotated, aerodynamically shaped blades made by anodized aluminium. Every blade is rotated by two plastic gears. The plastic gears are inside the frame to avoid pollution. The blades in the length they have seals in rubber for better air-tightness. The blades angle is manually regulated. Air leakage when closed: CLASS 2 according to the standard ΕΝ 1751:1998. The connection of two dampers DA (in same or opposite rotation) is possible by using connection elements. The blades are parallel to the first mentioned dimension.

Also is available in the following executions:

DA-ON/OFF 220V: Adjustable with electric actuator on/off 220V.

DA-ANALOGUE 24V: Adjustable with electric actuator analogue 24V.
