Dospel WK Metal Air Extractor – High Power Inline Fan

The Dospel WK Metal Extractor is the robust, industrial-grade solution for growers who are tired of flimsy plastic fans and need serious airflow to keep their indoor garden thriving. This centrifugal inline fan is designed to move large volumes of air efficiently, ensuring your plants get the fresh CO2 they need while exhausting excess heat and humidity instantly.

Is your grow tent turning into a sauna every time the lights go on?

Heat pockets and stagnant air are the silent killers of a heavy harvest. If you ignore proper ventilation, you are inviting mold, powdery mildew, and heat stress that will stunt your plants and ruin the flavor of your buds. A weak fan just can't keep up with the pressure of a carbon filter and long ducting runs.

The Dospel WK Metal is the answer. With its galvanized steel body and high-torque motor, it pushes air with authority, ensuring your environment stays dialed in so your plants can focus on stacking weight rather than surviving the heat.

Maximum ventilation power for your indoor crop

This isn't just a fan; it's the heart of your Air Extraction System. The Dospel WK is built to withstand the harsh conditions of a grow room, running 24/7 without breaking a sweat. Its metal construction acts as a heat sink, cooling the motor and extending its lifespan far beyond that of cheaper plastic alternatives.

Whether you are running a small closet grow or a large room, this extractor ensures that the air exchange rate is high enough to replenish CO2 and remove stale air. It is specifically engineered to maintain pressure even when connected to ducting and filters, making it a reliable workhorse for any serious cultivator.

Key features and benefits in a nutshell

• Galvanized Steel Body: Unlike plastic, this metal housing is impact-resistant and dissipates heat, ensuring maximum durability and safety.
• High-Pressure Airflow: The centrifugal design moves more air against resistance, making it perfect for use with carbon filters and long duct runs in your Grow tents.
• Versatile Sizing: Available from 100mm to 315mm, allowing you to match the perfect airflow (up to 2100 m3/h) to your specific space size.
• Innovative Motor: Designed for power, it delivers higher RPMs to clear out heat faster than competitors of the same size.
• Included Supports: Comes with mounting brackets, making it easy to hang or mount to a wall right out of the box.

How to use it in a few steps

Setting up your ventilation shouldn't be a headache. Here is how to get your Dospel WK running smoothly:

1. Check the wiring: These units often come without a pre-wired plug. You will need to connect a standard power cable (available in our accessories section) to the terminal box.
2. Mount the fan: Use the included brackets to secure the fan at the top of your grow space. This is where heat accumulates, so it's the most efficient spot for extraction.
3. Connect the ducting: Attach your aluminum or acoustic ducting to the flange. Secure it tightly with a metal clamp or duct tape to prevent air leaks.
4. Add filtration: If you want to be discreet, connect an Odor eliminator for weed (carbon filter) to the intake side of the fan.

Frequently Asked Questions

Is the Dospel WK Metal Extractor loud?

Because it has a metal body and a powerful motor, it can be slightly louder than insulated plastic fans. However, the noise is a trade-off for superior power and durability. Using acoustic ducting can significantly reduce the sound.

Does it come with a power cable?

No, like many industrial-grade extractors, it does not include a cable. You will need to purchase a standard cable and plug separately and wire it to the terminal block.

Can I use a speed controller with this fan?

Yes, the Dospel WK motors are generally compatible with standard voltage-based speed controllers, allowing you to dial down the power when you don't need maximum airflow.

Which size do I need?

Calculate the volume of your room (Length x Width x Height). Multiply that by 60 to get the air exchange per hour. Choose the model that exceeds that number to account for the resistance of filters and ducting.

Personal Experience of Pevgrow’s CEO (Alan)

I've always been a fan of metal gear because it just feels like it's built to last. When I held the Dospel WK for the first time, I knew it wasn't a toy. It’s heavy, solid, and when you turn it on, you can feel the torque. In my setups, I use these when I have a lot of lights running and I need to be 100% sure the heat is getting pulled out.

One thing to keep in mind is the wiring—it takes five minutes to hook up a cable, but once it's done, you have a beast of a fan. I prefer these over the cheap plastic axial fans any day of the week because they actually handle the pressure of a carbon filter without choking. If you want reliability, this is a solid choice.
