Silenced Mammoth EC Fan Move a LOT of air as quietly as possible with the Mammoth S-Max. This powerful EC fan uses half the energy of a standard AC fan while delivering incredible levels of static pressure. It also comes with an integrated controller, allowing users to change the airflow levels without needing purchase of a separate unit. Silent Running Featuring aluminium casings with integrated noise dampening foam, S-Max fans operate extremely quietly, keeping your grow space as discreet as possible. This design reduces sound levels to as low as 50dB, which is roughly equivilent to the noise level found in a quiet office environment. 50% More Energy Efficient EC fans are by far the most cost efficient duct fans on the market. On average, they use just half the energy of regular AC fans! This means that you can recoup the initial outlay costs through energy savings. As electricity costs gets more and more costly, it makes sense to invest in equipment that will save you tons of cash in the long-run. Built-In Fan Controller The S-Max also comes with a fully adjustable speed controller, meaning growers can operate the fan at a level that best suits their plants' environmental requirements, as well as their budget. Supreme Levels of Static Pressure Don't be fooled by the low energy consumption rates - Mammoth S-Max fans are extremely powerful. The largest fan in the range can move an incredible 2987 cubic metres of air per hour. This pulls fresh air into the grow space (even if you're not using an intake fan), keeping conditions cooler while controlling moisture levels and drawing in fresh CO2 for your plants to use in photosynthesis.
