The Imperial R2 Pro is a convertible exhaust and intake hood that transforms between functions by removing its internal damper. Built from painted galvanized steel rather than plastic, this 4-inch venting solution targets HVAC contractors and homeowners who need versatile, durable venting that withstands Montana’s temperature extremes while maintaining energy efficiency.
Convertible Design and Energy Efficiency
The R2 Pro easily converts from an exhaust hood to an intake hood by removing the internal damper. This flexibility matters for contractors juggling multiple venting needs — clothes dryer venting (must remove screen), bathroom exhaust fan venting, kitchen range hood (through-the-wall), fresh air intake for HVAC systems, and general mechanical ventilation.
The energy efficiency comes from multiple design elements working together. The unit prevents back-draft and heat loss while allowing for maximum airflow efficiency. More specifically, it’s constructed to be energy-efficient with an air-tight seal to reduce energy loss. The weighted damper serves double duty — blocking cold air intrusion when closed while maintaining smooth airflow when operating.
For Montana’s heating-dominated climate, these efficiency features translate to real savings. The air-tight seal prevents the constant heat loss that plagues cheaper vents, while the weighted damper stops that annoying backdraft rattle during chinook winds.
Material Durability: Why Galvanized Steel Beats Plastic
Made from durable painted galvanized steel to withstand harsh weather conditions, the R2 Pro is much stronger than plastic alternatives. The comparison matters because it’s more durable and weather-resistant than plastic louvered vents (e.g., Deflecto, Dundas Jafine), and the fixed hood design provides better protection against pests and rain compared to some lightweight louvered designs.

The galvanized steel construction handles Montana’s freeze-thaw cycles without cracking like plastic vents do after a few winters. The white galvanized steel surface can be painted to match the exterior color of the home — critical for maintaining curb appeal on custom builds where every detail matters.
Installation and Compatibility
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 isn’t optional — lint buildup against a screen creates a fire hazard and blocks airflow. Some ‘dryer-specific’ vents have wide-gap louvers to avoid this issue, but the R2 Pro’s convertible design means you configure it for each specific use.
Compatible with standard 4-inch rigid or flexible ducting (aluminum, semi-rigid, or plastic/foil), the unit works with wood, brick, or siding wall types with proper flashing/caulking.
It can be painted post-installation to match home exterior — useful when the siding color doesn’t show up until after rough-in.
The Bottom Line
The Imperial R2 Pro earns its place through versatility and durability. The warranty covers 1 year limited from Imperial Manufacturing Group covering defects in material and workmanship. No specific customer reviews were found on major retailer sites for this specific SKU, and no specific certifications (UL, CSA, etc.) were explicitly listed on manufacturer or retailer pages for this passive metal vent component.
For contractors tired of callbacks from cracked plastic vents or homeowners dealing with backdraft issues, the R2 Pro’s galvanized steel construction and convertible design solve real problems. It costs more than disposable plastic alternatives, but in Montana’s climate, paying once for steel beats replacing plastic every few years.
Frequently Asked Questions
Q: Can I use the Imperial R2 Pro for both dryer venting and fresh air intake?
A: Yes, but not simultaneously. The unit easily converts from an exhaust hood to an intake hood by removing the internal damper. For dryer use, you’ll also need to remove the pest screen to prevent lint clogs. Each installation serves one purpose — you’d need separate units for concurrent exhaust and intake applications.
Q: How does the R2 Pro compare to plastic dryer vents in cold weather?
A: The painted galvanized steel construction withstands harsh weather conditions and is much stronger than plastic alternatives. While plastic vents crack during freeze-thaw cycles, the steel construction handles temperature extremes without degrading. The design prevents back-draft and heat loss while allowing for maximum airflow efficiency — features that matter more in cold climates.
Q: What sizes does the Imperial R2 Pro come in?
A: The available research only covers the 4-inch model (VT0517). The hood fits into a 4-inch wall opening and is compatible with standard 4-inch rigid or flexible ducting.
Q: Do I need special tools or materials for installation?
A: The unit is designed for straightforward wall installation. You’ll need standard venting installation tools and materials. It’s suitable for wood, brick, or siding wall types with proper flashing/caulking. The ability to paint it post-installation means you can match it to your siding after installation using standard exterior paint.
