Soundproof Fan Box Metallic Tornado (7000 m³/h) – Cyclone 450mm

The Metallic Tornado (7000 m³/h) Cyclone 450mm Mouth is the heavy artillery you need when standard ventilation just doesn't cut it. This is a high-performance soundproof fan box designed specifically to move massive amounts of air in large grow rooms or industrial setups, ensuring your climate remains stable and your operation stays discreet.

Why do you need this beast in your grow room?

Let’s be real: managing the climate in a large indoor setup is a constant battle. You are likely dealing with dozens of lights generating intense heat, and humidity spikes that threaten to ruin your crop with mold or botrytis. Are you tired of daisy-chaining multiple weak fans that vibrate, make a racket, and still fail to cool the room down?

There is nothing worse than walking into your grow room and feeling that suffocating wall of heat and stale air. It stresses your plants, stunts their growth, and invites pests. Plus, the noise of a standard industrial fan can be a dead giveaway to neighbors or prying eyes, turning your passion into a source of anxiety.

The solution is the Metallic Tornado. With a staggering flow rate of 7000 m³/h, this unit doesn't just move air; it completely replaces the atmosphere in your room in seconds. It combines the raw power of a Cyclone motor with a soundproofed housing that dampens vibration and noise, giving you the perfect balance of performance and stealth.

If you are scaling up: how this product helps you

Moving from a bedroom grow to a large facility or one of our large grow tents can be intimidating. You might worry about the complexity of installing industrial equipment. The Metallic Tornado is designed to bridge that gap, offering professional power with an installation process that is surprisingly straightforward.

• Plug & Play Logic: Despite its size, it comes with pre-installed crown sleeves, making duct connection intuitive.
• Forgiving Power: Its massive capacity gives you a huge margin for error; even if your lights run hotter than expected, this fan can handle the heat load.
• Instant Climate Correction: Beginners often struggle to dial in humidity; this fan clears moisture so fast that mold doesn't stand a chance.

If you are a pro: why it deserves a place in your kit

For the veteran grower, control is everything. You know that maintaining a perfect VPD (Vapor Pressure Deficit) requires consistent airflow that doesn't fluctuate. The Metallic Tornado offers the reliability and static pressure needed to pull air through long duct runs and heavy-duty anti-odor carbon filters without losing efficiency.

• Multiple Intake Points: With three 250mm inlets, you can draw air from different areas of the room or multiple tents simultaneously.
• Built to Last: The Cyclone motor is engineered for continuous operation, meaning you won't wake up to a burnt-out fan in the middle of flowering.
• Stealth Operation: The acoustic foam lining and MDF structure absorb the frequencies that usually penetrate walls, keeping your operation low-profile.

Advantages and benefits for any level

• Total Silence: The soundproof box drastically reduces decibels, allowing you to run high power without the noise pollution.
• Temperature Control: Evacuates heat from HPS or LED fixtures instantly, keeping your canopy at the optimal temp.
• Odor Management: Creates strong negative pressure, ensuring no smell leaks out of the room (when paired with a filter).
• Versatility: The 450mm outlet is compatible with standard industrial ventilation tubes (using reducers if necessary) or direct large-bore ducting.
• Durability: Heavy-duty sheet metal corners and moisture-resistant materials ensure a long lifespan in humid grow environments.

Typical mistakes this product helps you avoid

Many growers try to save money on ventilation, only to pay the price later. The Metallic Tornado prevents the most common environmental disasters.

• Heat Stress: Prevents the "hot spots" that cause foxtailing and fluffy buds.
• The "Jet Engine" Effect: Avoids the suspicion caused by loud, unboxed industrial fans.
• Air Stagnation: Eliminates dead air pockets where powdery mildew loves to breed.
• Under-powering Filters: Provides enough static pressure to ensure your carbon filter actually works 100%.

Frequently Asked Questions

Is the Metallic Tornado difficult to wire?

It requires a standard electrical connection, but due to its power (1500W / 12A), we recommend ensuring your circuit breaker can handle the load. If you are unsure, consulting an electrician is always a safe bet.

Do I need a speed controller?

While not strictly necessary, using a frequency controller is highly recommended. It allows you to dial down the 7000 m³/h power during the night cycle or winter months, saving energy and reducing noise even further.

How do I hang this box?

The unit weighs 70kg. Do not hang it from standard tent poles. It should be placed on a sturdy grow table, the floor, or suspended from a structural beam using heavy-duty chains or straps.

What size filter should I use?

You must match the airflow. Look for a carbon filter rated for at least 7000 m³/h or slightly higher to ensure air passes through the carbon bed effectively without strangling the fan.

Personal Experience of Pevgrow’s CEO (Alan)

"I've seen too many commercial grows fail because they underestimated their ventilation needs. They buy ten small fans instead of one big one, creating a nightmare of wiring and noise. If you are running a serious setup, the Metallic Tornado is a game-changer.

For the guys just scaling up, this box gives you peace of mind—you know heat won't be an issue. And for my pro friends, the ability to duct from three different sources (thanks to the 3x250mm inlets) into one central extraction point is a massive efficiency hack. It’s big, it’s heavy, but it’s the heart of a healthy grow room."
