Louver Dampers - Opposed and Parallel Blade
 |
 |
 |
These dampers are suitable for flow modulation and effective isolation when blades are closed. Opposed blade dampers offer the least disturbance to flow patterns in ducts. Each blade is carefully fitted for precise operation in parallel or opposed motion and thus creates highly controlled passages for gas. The blades are designed to adequately handle all loads for the specified upset conditions. |

A maximum center span deflection is determined by our engineering department, so as to ensure smooth and trouble free operation. The drive shafts are carried in practically maintenance free, sealed, self aligning Joiner Systems™ "Freelub" bearings. The shaft passage throught the damper frame is sealed by means of a floating packing gland. |
