When looking for a fan with high air output, low energy consumption, and the ability to withstand harsh, corrosive environments (such as pig houses), our Fiberglass Cone Fan is the right choice.High Stable Negative Pressure Range: Thanks to its unique design, these fans have a high negative pressure range. Very suitable for use in applications such as evaporative cooling, air filtration, and agricultural drying.Energy-saving Vplus Models Available: Save energy with optional Vplus technology. Vplus fans are among the most energy-efficient fans in the world.Withstands the Harshest Corrosive Environments: These fans are made entirely of corrosion-resistant materials, such as high-tech synthetic plastics, fiberglass, and treated metals, making them ideal for use in harsh environments.Efficient Ventilation, Large Air OutputWith its aerodynamic design, the Multifan Fiberglass Cone Fan is one of the most energy-efficient fans in the world. Most importantly, due to the use of high-tech engineered plastic components, these fans can also withstand some of the harshest climates. This makes the Fiberglass Cone Fan the best choice in many ways. This type of fan is typically used in large buildings, such as pig and cattle houses, to effectively keep the air fresh. These fans can also be combined with light traps or air filters.Advantages:Withstands corrosive climatesMost energy-efficient fan typeHigh airflowTechnical Data:MetricImperialAvailable Ø45 - 140cm18" - 54"Maximum Airflow67,500 m³/h37,700 cfmMaximum Pressure125 Pa0.5 S.P.VplusYesYesApplication Areas: This type of fan is suitable for the following segments:Pig farming: Fresh air not only improves animal welfare but is also crucial for pigs.Poultry: Improves the living environment in poultry houses, making poultry healthier and grow faster.Dairy: Regularly updating the air in cattle houses to prevent humidity problems or creating a constant flow of fresh air to prevent heat stress.Greenhouses: Mechanical ventilation during the day helps cool horticultural greenhouses and reduce humidity.Save More Energy with Vplus Technology: Our fans with Vplus technology are among the most energy-efficient fans in the world. With their extremely durable controllers and permanent magnet technology, they can save up to 85% energy compared to standard fans.Short payback periodBest performance/efficiency ratioMaximum energy savingsCustomer Testimonial: Clint Jaeger, Jaeger Farm, Keota, Iowa, USA: “We have a pig house on our farm that can accommodate 7,500 pigs. The effect after using the Multifan fan is very good. These projects started smoothly, were easy to install, and saved costs, which solved a big problem. When choosing a fan, what I value most is the initial investment cost of the fan itself and the cost of replacing parts. This Vplus fan also has a significant effect on the growth of livestock. This fan allows a large amount of air to circulate, providing a very dry environment for the pigs in the pig house.”Key Features / Technical Specifications:Available diameters: 45 - 140 cm (18" - 54")Maximum airflow: 67,500 m³/h (37,700 cfm)Maximum pressure: 125 Pa (0.5 S.P.)Vplus energy-saving technology availableCorrosion-resistant materials: high-tech synthetic plastic, fiberglass, treated metalApplications: pig farming, poultry, dairy, greenhouses
