High-Capacity Airflow & Aerodynamic Design
The RAJA Roof Ventilating Fan (R834) is engineered to tackle high-demand ventilation needs. Installed at the terminal point of your exhaust system, its high-efficiency centrifugal impeller draws out heavy volumes of warm, humid, or contaminated air. The contoured metallic weather hood redirects exhaust downward and away from the building, preventing wind blow-back and maintaining optimal static pressure even in adverse weather conditions.

Heavy-Duty Weatherproof Construction
Built to withstand continuous exposure to the elements, this unit features a reinforced metallic housing with an anti-corrosive finish. Beneath the weather dome sits a 360-degree protective wire safety cage that prevents birds, rodents, and airborne debris from entering the ventilation ductwork. This ensures long-term operational safety and dramatically reduces maintenance overhead.

Precision Engineering & Electrical Stability
Operating on a standard 220V / 50Hz power frequency, the fan’s 197W motor balances maximum exhaust volume with energy efficiency. Precision-balanced internal rotors minimize mechanical vibration, ensuring quiet, smooth operation throughout the ventilation shaft. The wide square mounting base with pre-drilled corner anchor points allows for fast, secure attachment to flat or sloped roof structures.
