Rhino Ultra Silent EC Fans

Serious airflow, half the noise

The Rhino Ultra Silent EC Fan range packs over 20 years of Rhino ventilation experience into an energy-efficient EC motor inside an acoustically dampened, sealed steel body, used in hundreds of thousands of grow rooms worldwide. Available in 6", 8", 10" and 12", it delivers from 530 up to 2987 m3/h of extraction while running far quieter than a standard fan, so you get strong airflow without your setup announcing itself.

Key Benefits

• EC technology for energy-efficient running with no phantom power drain
• Acoustic dampening foam and sealed steel body for roughly half the noise of the non-silenced Ultra
• Up to 2987 m3/h airflow across four duct sizes
• No air leaks, so the room reaches target temperature quickly
• Built-in eyelets for straightforward mounting anywhere
• Varispeed control compatible, and pairs with Rhino Pro Filters

Need strong extraction without the fan noise giving your grow away?

Loud extraction is one of the most common complaints for growers running a tent in a residential space, and standard AC fans waste energy at full speed when they don't need it. The Ultra Silent's EC motor and acoustic foam cut both energy draw and noise, while the sealed steel body stops the air leaks that slow how fast a room hits temperature.

How to Use

• Pick the size for your room and target air changes (6" to 12").
• Mount using the built-in eyelets and connect ducting to a carbon filter such as a Rhino Pro Filter.
• Run continuously, using the Varispeed or a compatible RJ45/3-pin controller to hold your target temperature and humidity.
• Keep intake and extraction balanced for a slight negative pressure in the tent.
