40-FOOT CONTAINER ROOF VENT SYSTEM

Double Vent System for 40' Shipping Container Need a single-vent system for a 20' container? [Click here.] Give your 40-foot shipping container real airflow with a complete no-weld ventilation package built specifically for standard 3.5" corrugated container roofs. Shipping containers trap heat and moisture. Without proper ventilation, that trapped air can contribute to extreme interior temperatures, condensation, rust, mold, odors, and damage to tools, equipment, inventory, or personal belongings. This complete 40' package includes: Two AdaptAIR™ roof vent adapters Two 12" wind-powered turbine vents Twenty 2.5" intake vents — included free, a $100 value Installation hardware and step-by-step photo instructions Why Intake Vents Matter Roof turbines are designed to exhaust hot, moist air from the top of the container. But for air to move out efficiently, fresh air must also be able to enter. The included intake vents create dedicated entry points for replacement air, helping the turbine vents produce better airflow through the container rather than pulling only through small door gaps or random leaks. For a 40' container, the two-turbine and twenty-intake-vent setup is designed to provide airflow across the full length of the container. What’s Included Two (2) AdaptAIR™ Roof Vent Adapters Two (2) 12" Wind-Powered Turbine Vents Two (2) 10-packs of 2.5" Intake Vents — 20 total Two (2) Installation Kits, including: Drill bits Driver bits Self-tapping screws Abrasive pad Step-by-step photo instructions Sealant is not included. For proper installation, we recommend Chem Link M-1 Structural Adhesive/Sealant. M-1 is designed for exterior bonding and sealing applications involving metal flashing and roofing materials. Do not use standard silicone caulk, latex caulk, roof cement, or sealants not intended for exterior metal roofing and flashing applications. Important Fit Note Fits standard 3.5" shipping container roof corrugation only. The AdaptAIR™ roof adapter is not designed for 3", 5.5", or 6.5" ribs, and it is not intended for side-wall installation. Please check the measurement chart before ordering.
