4000 Steel Control Damper (Unsealed)
The Alumavent 4000 series is a standard performance unsealed steel control damper engineered with a rugged one-piece frame that locks together without bolts, screws, or rivets. The triple-vee blade design provides maximum strength, and non-corrosive bearings, concealed linkage, and a lock-together frame make the 4000 series very low maintenance. It is well suited for low to medium velocity and pressure commercial applications and is also ideal as a manual balancing damper.

The 4000 series is designed for general commercial HVAC applications where a reliable, low-maintenance steel control damper is required without the added cost of blade seals. The lock-together frame construction eliminates fastener-related maintenance issues common in traditional damper designs, and the triple-vee blade profile provides strong structural rigidity across the full range of panel sizes. Its wide operating temperature range and manual balancing capability make it a versatile choice for air handling systems in commercial and institutional buildings.
