The Imperial R2 Pro exhaust/intake hood solves a simple problem that plastic vents can’t touch — surviving Montana weather without cracking, warping, or letting pests move in. Made from durable painted galvanized steel to withstand harsh weather conditions; much stronger than plastic alternatives. At 4 inches diameter, it handles dryer venting, bathroom fans, range hoods, and HVAC fresh air intake with one convertible design.
Why Contractors Choose Galvanized Over Plastic
More durable and weather-resistant than plastic louvered vents (e.g., Deflecto, Dundas Jafine). That’s the core advantage. Plastic exhaust hoods crack after a few freeze-thaw cycles. UV degradation turns them brittle. The Imperial’s painted galvanized steel construction handles temperature swings from -30°F to 100°F without flinching.
Easily converts from an exhaust hood to an intake hood by removing the internal damper. This flexibility matters when you’re stocking a truck for different jobs. One SKU covers bathroom exhaust fans, dryer venting, range hood exhaust, and fresh air intake for HRVs or ERVs. Remove the damper for exhaust applications. Keep it installed for intake.
The fixed hood design beats louvered alternatives for weather protection. Fixed hood design provides better protection against pests and rain compared to some lightweight louvered designs. No moving parts to freeze shut. No gaps for wasps to build nests. The downward-facing opening sheds rain while maintaining airflow.

Designed for straightforward wall installation. The hood fits into a 4-inch wall opening. For dryer venting, the pest screen must be removed to prevent lint clogs. That screen removal requirement is critical — lint buildup on screens causes dryer fires. Requires manual screen removal for dryer applications to prevent lint buildup, whereas some ‘dryer-specific’ vents have wide-gap louvers.
Compatible with standard 4-inch rigid or flexible ducting (aluminum, semi-rigid, or plastic/foil). Suitable for wood, brick, or siding wall types with proper flashing/caulking. The 17-inch length provides enough depth for proper wall penetration while maintaining the downward angle that sheds water.
Energy efficiency comes from the tight seal. Designed to prevent back-draft and heat loss while allowing for maximum airflow efficiency. Constructed to be energy-efficient with an air-tight seal to reduce energy loss. In Montana’s heating climate, every air leak costs money. The Imperial’s solid construction and removable damper create a positive seal when closed.
The white galvanized steel surface can be painted to match the exterior color of the home. Unlike plastic that resists paint adhesion, the galvanized surface takes paint properly after light scuffing and priming.
1-year limited warranty from Imperial Manufacturing Group covering defects in material and workmanship. Standard warranty for a passive ventilation component.
Frequently Asked Questions
Can this hood handle Montana’s temperature extremes?
Galvanized steel handles freeze-thaw cycles better than any plastic alternative. The painted finish protects against corrosion, while the steel substrate won’t crack or warp from temperature swings.
Do I need to remove the screen for bathroom exhaust fans?
No. Keep the screen installed for bathroom fans to prevent pest entry. Screen removal is only required for dryer venting where lint accumulation creates a fire hazard.
How does the exhaust-to-intake conversion work?
The internal damper lifts out completely. For exhaust applications (dryers, fans), remove it for unrestricted airflow. For fresh air intake, keep it installed to prevent backdrafts.
What’s included with the hood?
The R2 Pro Hood assembly, integrated removable damper, and pest-control screen. No additional purchase required for basic installation.
Does this meet code for dryer venting?
Yes, when installed with the screen removed as required. The 4-inch diameter matches standard dryer duct sizing. Always follow local code requirements for termination height and clearances.
