Unique Construction Features Fabra Hood Style • Hinged Hood - All sizes feature a hood which may be hinged to provide quick access to the motor and drive assembly. Access may be gained by simply removing two of the four hood fasteners or all fasteners for complete removal.
Unique Construction Features FABRA HOOD STYLE - Models LD and LB have a rib-lock aluminum housing. Hood panels are interlocked and attached to sturdy aluminum rails. (Galvanized housings are optional). HINGED ACCESS - The entire hood assembly on models LD and LB can be hinged open for access to the internal fan components.
Options and Accessories BIRDSCREEN - Galvanized mesh is standard. Optional aluminum or stainless steel rigid wire are also available. HOOD INSULATION - Hood insulation is dual- density to minimize condensation, reduce thermal transfer, and enhance sound absorption at high and low frequencies.
Severe Duty Option SEVERE DUTY - Specifically designed for applications with extremely high structural design load requirements. The severe duty models LDP and LBP are far superior to any centrifugal roof exhaust fan currently in the market. Designed with structural steel supports and ESD-603D louver blades, the severe duty louver enclosure (SDLE) may be used in any application which requires a fan to endure high winds with the potential of wind blown debris.
