Lau’s heavy duty commercial control damper is a ruggedly built damper designed especially for manual balancing applications. It offers an economical manufactured product alternative to the “shop built” items often installed.
Features available with other commercial control dampers are standard with the C305. Non-stick, non-corrosive bearings assure long damper life and ease of operation. Linkage is shake proof and low maintenance. Hex axles lock positively with blades, without screws or welds that might shake loose. Steel frame design interlocks without bolts, screws or rivets and features internally braced corners to reduce racking.
