Tubular Extractor VK Ø 315mm (1325 m3/h) – Powerful Air Renewal for Large Grow Rooms

The Tubular Extractor VK Ø 315mm (1325 m3/h) is the heavy-duty lung your indoor cultivation needs to guarantee explosive growth without climate interruptions. This device isn't just a fan; it's the definitive tool to move massive amounts of air, ensuring your plants always breathe fresh oxygen while expelling heat and humidity instantly, creating the perfect ecosystem for a record-breaking harvest.

Why are your climate parameters always fluctuating?

There is nothing more frustrating for a grower than checking the thermometer and hygrometer and seeing different values every day. One day the temperature spikes because the air isn't moving fast enough; the next, humidity pockets form in the corners of your room. This inconsistency makes it impossible to dial in your nutrient schedule or predict your harvest date, leaving you feeling like you're gambling rather than growing.

This lack of control doesn't just stress you out; it stresses your plants, stunting their growth and inviting pathogens like mold or powdery mildew. You waste hours tweaking passive intakes or oscillating fans, trying to guess why your environment won't stabilize, while the quality of your final product slowly degrades due to heat stress or poor air exchange.

The Tubular Extractor VK Ø 315mm is the solution to stop guessing and start controlling. With a flow rate of 1325 m3/h, this equipment ensures that the air in your room is completely renewed in minutes, eliminating heat pockets and stale air, providing the stability you need to replicate professional results cycle after cycle.

Why this product helps you get more consistent results

Consistency in cultivation comes from reliability in your equipment. The VK 315mm is built with a high-quality durable plastic casing that resists corrosion and damp environments typical of an Air Extraction System. Its centrifugal impeller design is engineered to maintain high pressure even when connected to long duct runs or carbon filters, meaning the airflow doesn't drop drastically just because you added a filter.

By having such a high power reserve (1325 m3/h), you are not running the fan at its absolute limit to barely scrape by. You have the muscle to clear out heat instantly when your lights are at full power. This capability allows you to maintain a "flat line" on your climate charts, which is exactly what cannabis plants love for maximum terpene and trichome production.

Factors that influence the result and how to control them better

• Temperature Spikes: With 1325 m3/h, you can evacuate heat from powerful HPS or LED fixtures instantly, preventing leaf burn.
• Relative Humidity (RH): Rapid air exchange prevents moisture buildup after watering, significantly reducing the risk of botrytis.
• CO2 Depletion: Plants consume CO2 rapidly; this extractor ensures a constant supply of fresh, CO2-rich air from outside.
• Odor Control: Its high static pressure makes it the perfect match for heavy-duty Can filters - Carbon filters, ensuring no smell escapes your room.
• Air Circulation: It eliminates dead zones where stale air accumulates, ensuring every plant gets the same breeze.

Recommended routine to achieve good results every time

1. Calculate: Ensure your room size requires this much power (ideal for spaces around 3x3 meters or larger).
2. Install High: Mount the extractor at the highest point of your room where heat accumulates.
3. Secure Connections: Use quality clamps to connect it to your ducting to prevent air leaks that reduce efficiency.
4. Check Pressure: When running, your tent walls should suck in slightly (negative pressure), ensuring no odors leak out.
5. Monitor: Use a Climate Control device to automate the fan speed based on temperature for total precision.
6. Clean: Wipe down the blades after every harvest to maintain maximum aerodynamic efficiency.

Advantages and benefits of that consistency

• Total Confidence: You can leave your grow room knowing the climate won't spiral out of control.
• Heavier Harvests: Stable environments allow plants to focus energy on bud production rather than survival.
• Equipment Longevity: A robust motor designed for continuous operation lasts years, saving you replacement costs.
• Scalability: This fan has enough power to handle upgrades in lighting or room size without needing to be replaced immediately.

Frequently Asked Questions

Is this extractor too powerful for a 1.2m x 1.2m tent?

Yes, for a standard 1.2m tent, 1325 m3/h is likely overkill and might create too much negative pressure (sucking the walls in too hard). This model is best suited for larger rooms or tents (e.g., 2.4m x 1.2m or 2.4m x 2.4m).

Does it come with a speed controller?

This specific model is single-speed. However, it is compatible with external voltage regulators or climate controllers if you want to adjust the flow rate based on temperature.

Can I use it as an intake fan?

Absolutely. While it's a beast at extraction, in very large setups, you can use it as an active intake fan to push massive amounts of fresh air in, provided you have an even larger extractor to maintain negative pressure.

Personal Experience of Pevgrow’s CEO (Alan)

"I've seen too many growers try to save money on ventilation, buying weak fans for big rooms, and they always pay the price with moldy buds or heat-stressed plants. When I'm setting up a larger space, consistency is the only thing I care about. I don't want to wake up to a sauna."

"The VK 315mm is one of those workhorses that just keeps going. I've used this specific flow rate (1325 m3/h) in setups with multiple 600W lights, and it keeps the temp perfectly in the sweet spot. It's loud because it moves a ton of air, but the peace of mind it gives you is worth every decibel. You plug it in, and you know your environment is locked in."
