Rhino Ultra Silenced EC Fan — Half the Noise, Full Power Extraction
Best for: Growers who need serious extraction but can't afford the noise — residential setups, shared homes, or anywhere discretion matters
Our thoughts
This is a proper workhorse fan that actually lives up to the "silent" claim. EC motor technology is genuinely quieter than older AC fans — no humming, no buzzing, just reliable extraction that won't keep your household awake. One we recommend a lot for first-time buyers in noise-sensitive spaces.
The Rhino Ultra Silenced EC Fan is a high-performance inline duct extraction fan built with electronically commutated (EC) motor technology and acoustic foam lining that cuts noise by up to 50% compared to non-silenced alternatives. It's designed for growers who need maximum airflow without the acoustic headache — whether you're running a bedroom grow, a shared flat, or anywhere neighbours come into the equation.
How it compares
This sits in the premium silent fan category, competing directly with Can-Fan Isomax and U-GO Silent models.
- EC motors run 30–40% more efficient than traditional AC fans, cutting your running costs noticeably
- Up to 50% quieter than standard non-silenced extraction fans
- Full variable speed control (0–100%) with no buzzing or humming at lower speeds
- Soft-start function protects your electrical system and extends the fan's life
- Sealed steel body with acoustic foam — no air leaks, proper pressure control
Simply put: you're getting serious extraction with the discretion growers actually need.
Usage guidance
Installation
Built-in eyelets and wall-hanging brackets make mounting straightforward. Hang horizontally and well-supported from your tent or wall frame. Use bungee cords if you're in a noise-sensitive space — they'll dampen any residual vibration.
System setup
Attach to your carbon filter using short ducting and jubilee clips. Ensure the airflow arrow points away from the filter and toward your outlet. Pair with acoustic ducting and a compatible EC controller (RJ45, 3-pin, or jack plug — adapters supplied) for complete climate control.
Speed control
Use a Varispeed or digital controller to dial in your exact airflow needs. EC motors respond smoothly across the full range without the stepping or buzzing you get with older resistor-based controls.
Temperature and odour management
Adjust speed to maintain negative pressure in your grow space and manage both climate and odour control. The soft-start function ramps speed gently, protecting both the fan and your electrical system.

Who this is for
- Home growers in shared accommodation — flats, terraced houses, anywhere neighbours matter
- Bedroom or office-based setups where noise disruption is a real issue
- Environmentally conscious growers wanting lower power consumption
- Serious hobbyists who need reliable climate control without the acoustic compromise
- Anyone running multiple grow spaces where energy savings stack up across systems
Works best when paired with Rhino Pro carbon filters and acoustic ducting to maximise noise reduction across your entire extraction system.
Our take
EC technology genuinely changes the game for silent extraction. This fan delivers the airflow you need with roughly half the noise you'd get from a standard fan — no buzzing at low speeds, no humming, just clean, quiet operation. Add the 30–40% power savings and you've got a fan that pays for itself over time.
If you're in a noise-sensitive space or just want extraction that won't drive you round the bend, this is worth picking up while clearance stock lasts. Does exactly what it should, day in, day out.
