Tubular Extractor VK 250 (1150 m3/h) – Powerful Air Renewal for Indoor Growing

Meet the Tubular Extractor VK 250 (1150 m3/h), the heavy artillery your indoor grow needs to breathe properly. This device isn't just a fan; it’s the heart of your climate control system, designed to move massive amounts of air ensuring your plants always have the fresh oxygen they need to explode in size and resin production.

Is your grow room turning into a sauna?

We've all been there: you open the tent and a wave of hot, heavy, stale air hits you in the face. You worry that your plants are suffocating, that the humidity is spiking at night, and that you have absolutely no control over the environment. It feels like you are just winging it, hoping mold doesn't show up to ruin the party.

If you don't fix this fast, that heat stress will stunt your buds, turning them airy and weak, or worse, botrytis will rot your harvest from the inside out. The anxiety of checking the thermometer every hour is exhausting, and let's be honest, a small clip fan isn't going to save you when the lights are blazing.

The Tubular Extractor VK 250 is the tool that puts you back in the driver's seat. With a massive flow rate of 1150 m3/h, it sucks out heat and humidity instantly, replacing it with fresh CO2-rich air. It transforms a chaotic, stifling environment into a perfectly tuned ecosystem where you call the shots.

Stealth and efficiency in one robust design

When you are moving this much air, you might worry about drawing attention. However, the VK 250 is designed with a high-quality durable plastic casing that helps dampen the vibrations often found in metal equivalents. While a fan of this power will always make wind noise, its engineering focuses on airflow efficiency to keep mechanical noise to a minimum.

To maximize discretion, this unit is the perfect partner for a high-capacity carbon filter. By pairing them, you ensure that not only is the air renewed, but no unwanted smells escape your grow space. It allows you to run a high-performance setup without broadcasting it to the entire neighborhood.

Total control over your climate

• Massive Airflow: 1150 m3/h is enough to clear the air in large grow tents in less than a minute.
• Temperature Management: It rapidly removes the heat generated by HPS or powerful LED fixtures, keeping your VPD (Vapor Pressure Deficit) in the sweet spot.
• Humidity Regulation: Prevents moisture buildup during the dark cycle, which is the number one cause of mold.
• Durable Motor: Designed for continuous operation, so you don't have to worry about it failing mid-flower.
• Versatility: While usually used for extraction, in massive rooms it can serve as a powerful intake fan.

How to use it for maximum performance

Installing the VK 250 is straightforward, but doing it right makes all the difference. Follow these steps to ensure your plants get the best environment possible:

1. Positioning: Always mount the extractor at the top of your grow room. Heat rises, and you want to suck it out from the source.
2. Secure Connections: Use quality clamps to connect your ducting. Air leaks reduce efficiency and can let smells escape.
3. Filter Setup: If you are using a carbon filter (highly recommended for odor eliminator for weed), place it inside the tent connected to the intake side of the VK 250.
4. Vibration Check: Use bungee cords or suspension straps to hang the fan; this prevents vibrations from transferring to the ceiling or walls, keeping things quieter.
5. Maintenance: Wipe down the blades after every couple of harvests to prevent dust buildup from unbalancing the motor.

Benefits of a stable environment

• Peace of Mind: Stop stressing about heat waves; this fan handles them.
• Heavier Harvests: Plants that breathe better, eat better and grow bigger.
• Pest Prevention: Stagnant air invites bugs and mold; moving air keeps them away.
• Consistency: Achieve the same professional results crop after crop.

Frequently Asked Questions

Is the VK 250 loud?

With 1150 m3/h of power, there is wind noise—it's inevitable with this much air movement. However, the motor itself is smooth. We recommend using insulated ducting or a fan speed controller if you need to dial it down during the night cycle.

Can I use this with a speed controller?

Yes, the VK series works well with most voltage-based speed controllers, allowing you to adjust the Climate Control precisely according to the season or growth stage.

What size grow room is this for?

This model is a beast. It is ideal for spaces ranging from 1.5m x 1.5m up to 2.4m x 2.4m (or roughly 240x240cm tents), depending on your lighting heat load.

Personal Experience of Pevgrow’s CEO (Alan)

"When I moved from a small closet to a proper room setup, heat became my biggest enemy. I underestimated how much air I needed to move. The VK 250 changed the game for me. It's not just about cooling; it's about the 'freshness' of the plants. You can see them praying to the light because they have fresh CO2 constantly."

"My trick? I oversize my extraction slightly and run this fan with a controller at 70-80% power. It runs quieter, lasts longer, and I have that extra 20% of power in reserve for those super hot summer days. It's a lifesaver."
