HVLS Fans: The Most Energy The relationship between speed (rpm), diameter, airfoil shape, and the resul-tant size and momentum of a fan's air column yields exponential efficiencies an air column can sustain movement longer by leveraging its own momen-tum allowing air to entrain, circulate and reach corner to corner encom-passing circulation diminishes areas of unhealthy air. By operating at very low rpm, torque and wear are mini-mized and fan mechanical efficiencies are increased for a longer life cycle. Low rpm's equates to a highly efficient fan using very little power to operate pennies an hour! Thirty one 36 1hp high speed fans equal the cfm's of just one 24' HVLS 1hp fan saving over $20,000/year in electrical cost. Air and Water Systems: HVLS High Volume Low Speed Fans (pg 2) move large air masses without creating turbulence reducing thermal loads, electricity use, and mechanical cooling and heating times thermostat settings can be adjusted higher in summer and lower in winter to yield significant cost savings lowers overall maintenance and extends system life expectancies. Continuous mixing of incoming fresh air with stale processed air lowers amount of total ventilation - reduce the number of high speed exhaust fans. A fans large column of air pushing downward builds a comfortable deep floor jet of air that entrains outward requires no need for air speed velocities just 3-5 miles an hour for optimized cooling ef-fect reducing higher cost of heat cycling.engineered to ensure optimal acceleration, speed, and longevity (Multiple fans can be run off a single control panel).
