Our Multifan fiberglass cone fans are the right choice for high air output, low energy consumption, and resistance to harsh and corrosive environments, such as pig houses.Pressure Range: Thanks to their unique design, these fans have a high-pressure range. Perfect for use in panel cooling, air filters, and agricultural drying applications.Vplus: Save energy with optional Vplus technology. Vplus fans are among the most energy-efficient fans available in the world.Resistant to Hostile Environments: These fans are made exclusively from corrosion-resistant materials such as high-tech plastics, fiberglass, and treated metals, making them highly suitable for use in hostile environments.Efficient ventilation with high air performanceThanks to their aerodynamic design, Multifan fiberglass cone fans are among the most energy-efficient exhaust fans in the world. Additionally, they are resistant to some of the most extreme climates, thanks to the use of high-engineering synthetic parts. This makes them unique in their class in many aspects.This type of exhaust fan is commonly used in large buildings, such as pig and cow farms, to efficiently refresh the air. These fans can also be combined with light traps or air filters.Resistant to corrosive environmentsThe most energy-efficient exhaust fanHigh airflowTechnical DataMetricImperialAvailable in Ø45 - 140 cm18" - 54"Maximum air volume67,500 m³/h37,700 cfmMaximum pressure125 Pa0.5 S.P.VplusyesyesApplicationsPig farming: Fresh air not only improves animal welfare, but is also essential for pigs.Poultry: Improves living conditions for birds so they are healthier and grow faster.Dairy cattle: Regularly refresh barn air to prevent humidity problems, create a constant flow of fresh air, and avoid heat stress.Horticulture: Mechanical ventilation during the day can help lower the temperature inside greenhouses and reduce humidity.Customer TestimonialJaeger Farms in Keota, Iowa, USA, owned by brothers Dane and Clint Jaeger, uses 10 Multifan VPlus 54-inch fiberglass cone fans in one of their finishing houses for pigs. Clint Jaeger: “We have centers for pigs with 7,500 pigs on our farm. My experience with Multifan is very positive. They have a good start-up, are easy to install, and allow cost savings, which solves a big problem. When selecting a fan, the features I look for most are the initial costs of the fan itself and the replacement parts costs. The effects of these VPlus fans on the animals are significant. The fans move a large amount of CFM, which makes the environment very dry for the pigs inside this barn.”Resistant to corrosive environmentsMost energy-efficient exhaust fanHigh airflowAvailable diameters: 45 - 140 cm (18" - 54")Maximum air volume: 67,500 m³/h (37,700 cfm)Maximum pressure: 125 Pa (0.5 S.P.)Vplus technology available
