We recently acquired a large inventory of overstock items. These items are missing the manufacturer’s original packaging. They may also have minor cosmetic blemishes from storage (See Photos).
Product Identity: Delta T Systems 11" 24V DC Ignition Protected Axial Fan assembly.
Model Number: 500-311242IP (Distributed via Centek Marine).
Primary Function: High-performance marine engine room ventilation supporting active air intake or heavy exhaust cycles.
Input Voltage: 24V DC.
Amperage Draw: 7.4 to 8.5 Amps continuous load.
Volumetric Airflow: Yields up to 1,424 CFM (Cubic Feet per Minute) under zero-resistance, free-flow conditions.
Core Fan Footprint: Features an 11-inch internal shroud diameter.
Blade Geometry: Outfitted with a high-pitch, 5-blade fan hub assembly designed to maximize air movement at low noise thresholds.
Safety Classifications: Certified ignition-protected under marine standards SAE J1171, ISO 8846, and ISO 9097, making it entirely safe for volatile fuel vapor compartments.
