Lau’s high performance airfoil, low leakage control dampers offer sturdy, steel construction with interlocking frame design. The damper locks together without bolts, screws, or rivets that could shake loose. Frame corners are internally braced to reduce racking.
Axles positively lock to blades without screws or welds. Non-stick, non-corrosive bearings assure long life and ease of operation. Axles and bearings combine with a shake proof linkage for low maintenance operation.
The airfoil blade design and linkage is concealed in the frame out of the air stream to reduce turbulence for low pressure drop and noise generation.
Ruskiprene blade edge seals mechanically lock into the blade for superior low leakage in the closed position.
