RVK Tubular Extractors – Systemair · Silent & Durable Air Extraction for Grow Tents

The RVK Tubular Extractors by Systemair are the ultimate solution for growers who demand professional-grade reliability and silence in their ventilation system. This centrifugal duct fan is designed to run 24 hours a day without losing power, ensuring that your indoor garden maintains the perfect air exchange rate to maximize yields while keeping noise levels to an absolute minimum.

Why inconsistent airflow ruins your harvest

There is nothing more frustrating for a grower than seeing your plants suffer from heat stress or mold just because your extraction system couldn't handle a hot day or a humidity spike. When you rely on cheap, unstable fans, the environmental conditions inside your tent fluctuate constantly, leading to irregular growth, airy buds, and unpredictable harvest times.

This inconsistency doesn't just affect the plants; it takes a toll on you. You end up constantly checking the thermometer, worrying about noise leaking out, or stressing that the motor might burn out while you're at work. Instead of enjoying the process, you become a slave to your equipment, trying to guess why your parameters are never stable.

The RVK extractor eliminates this uncertainty completely. By providing a constant, powerful, and reliable airflow, it acts as the heartbeat of your grow room, stabilizing temperature and humidity automatically. With an RVK, you stop guessing and start controlling, ensuring that every crop gets the exact environment it needs to thrive.

Why this product helps you get more consistent results

The secret to the RVK's legendary consistency lies in its construction. Unlike generic fans, the RVK is built with fiberglass-reinforced plastic (polypropylene). This material is not only practically indestructible but also absorbs vibrations, making it significantly quieter than metal alternatives. This stability means the motor can run at optimal revolutions for years without the wear and tear that causes other fans to fail.

Furthermore, the backward-curved centrifugal blades are engineered to maintain high pressure even when connected to long runs of ducting or dense filters. This ensures that the air volume you calculate is the air volume you actually get, allowing you to repeat your successful growing conditions cycle after cycle without degradation in performance.

Factors that influence the result and how to control them better

• Temperature Control: Heat buildup is the enemy of quality. The RVK removes hot air efficiently, allowing your Climate Control systems to work less and last longer.
• Humidity Management: By ensuring constant air exchange (recommended 30 times per hour), it prevents the high humidity pockets that lead to Botrytis and powdery mildew.
• Odor Elimination: These fans have high static pressure, making them perfect for pulling air through dense Can filters - Carbon filters without losing suction power.
• Stealth: The low noise level (dB) allows you to run the fan at full power without alerting neighbors or roommates.
• Durability: Designed for continuous operation, you won't face the disaster of a fan failure mid-flowering.
• Versatility: Available in standard (A1) and high-power (L1) versions, allowing you to match the fan exactly to your tent's volume.

Recommended routine to achieve good results every time

1. Calculate: Measure your room (Width x Depth x Height) to get the volume in m3. Multiply by 30 to find the required m3/h flow rate.
2. Select: Choose an RVK model that slightly exceeds your calculation to account for the resistance of the carbon filter.
3. Install: Hang the extractor high up using bungee cords or straps to minimize vibration transfer to the structure.
4. Connect: Attach your Ventilation tubes securely, ensuring there are no sharp bends that could restrict airflow.
5. Check: Turn it on and check for negative pressure (the tent walls should suck in slightly).
6. Maintain: Clean the blades after every couple of harvests to maintain maximum aerodynamic efficiency.

Advantages and benefits of that consistency

• Peace of Mind: Knowing your environment is stable allows you to focus on feeding and training your plants.
• Higher Yields: Stable VPD (Vapor Pressure Deficit) leads to faster growth and denser flowers.
• Energy Efficiency: The motors are designed for low electrical consumption relative to their airflow output.
• Stealth Operation: The acoustic design keeps your operation discreet.
• Long-Term Savings: You won't need to replace this fan for years, unlike cheaper models that burn out quickly.

Frequently Asked Questions

How do I know which RVK model I need?

Use the formula: Room Volume (m3) x 30 = Required Flow (m3/h). For example, a 1.2x1.2x2m tent is roughly 3m3. 3 x 30 = 90 m3/h. However, always oversize to account for the carbon filter resistance. An RVK 125 A1 (220 m3/h) would be perfect for this space.

Is the RVK extractor loud?

RVK fans are among the quietest on the market due to their casing and motor quality. However, the sound of rushing air is inevitable in any powerful fan. Using soundproof ducting can make it almost inaudible outside the room.

Can I use a speed controller with the RVK?

Yes, RVK motors are compatible with voltage-based speed controllers, allowing you to dial down the speed (and noise) when full power isn't needed, such as during the vegetative stage.

What is the difference between A1 and L1 models?

The A1 models are the standard version, perfect for most setups. The L1 models are the "high power" versions with stronger motors, designed for setups with longer ducting runs or larger carbon filters that create more resistance.

Personal Experience of Pevgrow’s CEO (Alan)

I've been in this game for a long time, and if there's one piece of equipment I never gamble with, it's the extractor. I've seen too many crops ruined because a cheap fan died in the middle of a heatwave. For me, the RVK series is the "Kalashnikov" of extractors: it just works, no matter what.

In my personal tests, I've found that the RVK 150 L1 is a sweet spot for 1.2m x 1.2m tents when using high-intensity lighting. It has enough torque to pull air through a heavy-duty filter without whining, and the fiberglass casing really does dampen that annoying motor hum. It gives me that "set it and forget it" confidence that is priceless when you're busy.

One tip from my experience: don't skimp on the installation. Hang it properly to avoid vibrations. Once you dial in an RVK, you can literally run it for years non-stop. It's the best investment for stability you can make.
