Amana WS900QW-SC Seacoast Triple Protected Insulated PTAC Wall Sleeve | Heavy-Duty Galvanized Steel in Quiet White with Weather Board

Heavy-Duty Coastal Protection Built for Oceanfront Hospitality Properties

Coastal environmental conditions are notoriously brutal on HVAC infrastructure. Airborne salt spray, marine humidity, and ocean breezes quickly cause rust pitting and structural metal failure in standard un-coated wall sleeves. The Amana WS900QW-SC Seacoast Protected Wall Sleeve eliminates this vulnerability. Featuring factory-applied Seacoast Triple Protection, this sleeve combines a heavy-gauge galvanized steel core with specialized multi-stage protective coatings engineered to withstand continuous coastal exposure.

Rigid Galvanized Steel Construction & Weather Board Included

Constructed from 0.039-inch heavy galvanized metal, the WS900QW-SC maintains structural rigidity against exterior wall compression, brick weight, and coastal storm winds. The exterior surface is finished in Amana's Quiet White powder coating, establishing an exact aesthetic match with the front cabinet covers of Amana J-Series and K-Series units.

Each sleeve includes a heavy-duty temporary weather board fitted into the frame. This allows general contractors to seal wall openings against salt wind, rain, and construction dust during framing, drywalling, and exterior painting—weeks before final mechanical equipment arrives on site.
