The J&D Manufacturing 72" Mega Storm II Exhaust Fan is engineered for exceptional airflow performance and energy efficiency in large-scale barn ventilation systems. Built with a UV-resistant smooth-molded fiberglass housing, a reinforced triangle X-frame, and twin AX85 heavy-duty belts, the Mega Storm II delivers high-volume airflow up to 47,330 CFM at 0.10" static pressure. Available in high-performance and high-efficiency models with or without a performance-boosting cone, it's the go-to choice for dairy, poultry, and livestock operations demanding reliable, low-maintenance ventilation.
Features & Benefits
- Reinforced Triangle X-Frame: Improved triangle X-frame design delivers greater structural strength and long-term durability compared to standard frame configurations.
- Thick UV-Resistant Fiberglass Housing: Smooth-molded fiberglass resists chipping and corrosion far better than competitive models, ensuring reliable performance in harsh agricultural environments.
- Twin Belt Drive System: Twin AX85 heavy-duty industrial notched belts are easily accessible and require no tools for replacement - swap belts in seconds.
- High-Performance & High-Efficiency Models: Choose the model that best fits your operation - up to 47,330 CFM for maximum airflow or over 21 CFM/Watt for maximum energy savings.
- Optional Performance-Boosting Cone: Available with or without a cone to optimize airflow projection for your facility layout.
- Drainage Holes: Bottom housing drainage holes prevent moisture buildup, maintaining performance in wet or high-humidity environments.
- VFD Compatible (3-Phase Models): Three-phase models support Variable Frequency Drive operation for variable speed control and energy savings.
