Why do you need Agrifan? Because farmers know that quality and construction of a product makes a difference. Northwest Envirofan designed the Agrifan specifically for agriculture. Industrial and Commercial fans are perfect for clean, controlled environments, but they are not made to stand up to the harsh demands of agriculture. There is a big difference between industrial, commercial, residential, and agricultural grade fans. Make sure you get what you pay for.
Be aware that there are substantial differences in quality in the brands and styles of ceiling fans on the market. Do your research and find the fan that best suits your needs, has a good warranty, and a company that will stand behind their product.
