A roof exhaust system should not become an energy penalty every time the sun rises. Edmonds ecoPOWER hybrid roof-mount exhaust fans are designed to use wind energy first, then automatically draw supplemental grid power when site conditions demand dependable airflow. For facility managers, engineers, and contractors balancing ventilation performance against operating cost, that hybrid operating principle is the point: ventilation continues when wind output alone is not enough. These units are not …

Heat does not wait for ideal weather, operating schedules, or a utility-rate break. That is why Edmonds ecoPOWER Ventilation is a true Hybrid: it combines wind-driven rooftop exhaust with an efficient EC brushless DC motor to maintain ventilation when natural wind alone is not enough. The result is not a solar fan with limited daylight operation. It is a purpose-built hybrid ventilator designed to use wind energy when available and powered airflow when conditions require it. For architects, …

A fan rated at 20,000 CFM does not deliver 20,000 CFM in every building. That published number only applies at a stated static pressure, air density, fan speed, and test condition. Commercial Ventilation 101: learn how static pressure and temperature affect CFM before selecting exhaust, supply, roof-mounted, or wall-mounted equipment for a warehouse, manufacturing plant, grow facility, agricultural building, or equipment room. The practical issue is simple: if the real system creates more resist …

A home that is still 82°F at 9 p.m. after a hot day presents a different cooling problem than a home that is 82°F at 2 p.m. That distinction is central to the whole house fan vs ac decision. Air conditioning removes heat from indoor air regardless of outdoor conditions. A whole house fan uses cooler outdoor air to flush stored heat out of the living area and attic, making it exceptionally effective when evenings and mornings cool down. Neither system is automatically the better …

A poultry house can have enough installed fan CFM on paper and still struggle with wet litter, uneven bird comfort, ammonia odor, and poor tunnel air speed. The request, "Poultry Farming Ventilation & Light Deprivation - Talk with an Expert," is usually not just about buying exhaust fans. It is about making the entire house operate as one controlled air system. For broiler, breeder, pullet, and layer operations, ventilation must remove heat, moisture, dust, ammonia, and carbon dioxide withou …
