Hyperfans are a quiet, smooth and efficient hydroponic fan that has the highest CFM per watt of any fan in the industry. They also use half of the power and produce half of the heat when compared to traditional EC and DC motored fans. They have two ranges including their regular Hyperfan models and their stealth Hyperfans which produce little to no noise. They also have speed and temperature controllers which are extremely handy when dealing with environmental control within an indoor garden.
