Dampers for Coastal Installations: Moisture & Saltwater Resistance Options – Greenheck Model VCD-43
When it comes to HVAC systems in coastal environments, corrosion protection isn’t just a feature—it’s a necessity. Saltwater exposure, humidity, and moisture can significantly reduce the lifespan of standard galvanized steel dampers.
That’s why Greenheck designed the Model VCD-43, a best-in-class aluminum airfoil blade volume control damper engineered specifically for durability, energy efficiency, and long-term performance in harsh conditions.
The Greenheck VCD-43 meets AMCA certification for air performance and leakage and is built to comply with IECC efficiency standards. Its rugged 0.125-inch extruded aluminum frame ensures strength, while its low-leakage airfoil blades deliver precise airflow control even under high-pressure conditions.
Corrosion Protection Tailored for Coastal Applications
For installations near the ocean—or anywhere moisture and saltwater exposure are concerns—Greenheck offers multiple corrosion protection options to extend damper life.
Recommended Options for Coastal Installation:
Aluminum construction for superior corrosion resistance
Clear 215 R1 Anodized Finish
Type 316 stainless steel linkage, axles, and synthetic bearings for enhanced durability
TPE blade seals for maximum moisture protection
AMCA-certified low-leakage airfoil blades for high efficiency
Meets or exceeds IECC requirements and industry-leading pressure ratings
Engineered for coastal and high-humidity environments
Additional Options:
Stainless steel construction
204 R1 or custom colors
Type 316 SS bearings
Silicone blade seals
These features make the VCD-43 an ideal solution for coastal buildings, marine facilities, and other high-humidity environments, where long-term reliability and performance are critical.
Built to Perform – Even in the Harshest Environments
Greenheck’s corrosion-resistant design options are available across a wide range of control dampers, including the ICD-45 thermally broken aluminum damper and Severe Environment Stainless Steel Dampers (SEVCD-23 and SEVCD-33). Each model is engineered to meet demanding performance requirements while minimizing maintenance needs in corrosive environments.
Whether you’re designing a new HVAC system or upgrading an existing one, specifying corrosion-resistant dampers can significantly reduce downtime, improve energy efficiency, and extend equipment life.
