Prima Klima Extractor 2-Speed 160mm – Silent & Powerful Airflow

The Prima Klima 2-Speed Extractor (160mm) is the high-performance lung your indoor grow needs to breathe properly, offering you total control over temperature and humidity with a simple switch. This device defines what a professional Air Extraction System should be: robust, efficient, and capable of moving serious air volume without turning your room into a noisy factory.

Is it worth saving money on a cheap extractor fan?

We've all been there: trying to save a few bucks by buying a generic plastic fan that promises the moon. The reality? After two months, it starts rattling, loses power when you attach a carbon filter, and fails exactly when your plants are in full bloom and need it most. A weak extractor leads to heat pockets, mold, and stagnant air that suffocates your yield.

The real cost of "going cheap" isn't just the price of the fan—it's the risk of losing your entire harvest to Botrytis or having the smell of your crop leak out to the neighbors because the fan lacks the pressure to push through the filter. That frustration of seeing your electricity bill go up while your climate control goes down is a headache you don't need.

The Prima Klima PK160-2 is the solution that balances investment and performance. By paying for quality engineering now, you get a device that lasts for years, maintains constant pressure even with dirty filters, and actually saves you money on replacements and ruined crops. It earns its price tag every single day it runs silently in the background.

What value this product brings to your day-to-day life

The magic of this model lies in its versatility. Having two speeds (420 m³/h and 800 m³/h) means you essentially have two fans in one. During the vegetative stage or colder nights, you can run it on the low setting to maintain humidity and save electricity. When the lights turn on or the summer heat hits, flip the switch to high speed to instantly evacuate heat.

This adaptability translates to a much more stable environment inside your Grow tents. You won't have to constantly monitor the thermometer or buy speed controllers that often cause hum in AC motors. With the Prima Klima 160mm, you get consistent airflow that keeps your plants dancing and your stomata open for maximum growth.

Format, lifespan and efficiency

This UFO-style extractor is built with German engineering standards and a Swiss Mesan motor, designed for non-stop operation (24/7) without overheating.

• Format: Inline centrifugal fan with a 160mm flange (6 inches).
• Power: Adjustable flow rate of 420 m³/h (Low) or 800 m³/h (High).
• Durability: The backward-curved blades provide up to 15% more airflow efficiency than competitors, reducing wear on the motor.
• Housing: Made of fire-resistant polyamide (nylon), extremely impact-resistant.
• Efficiency tip: To extend its life, clean the dust from the blades after every harvest; a balanced fan lasts twice as long.

Advantages and benefits in terms of quality–price ratio

• Two-in-one functionality: You don't need to buy a separate controller; the integrated switch saves you money and setup time.
• High Static Pressure: Unlike cheap axial fans, this radial design pushes air forcefully through any Odor eliminator for weed without losing significant flow.
• Swiss Motor Reliability: The Mesan motor is legendary for its long life (up to 80,000 hours), meaning you won't be buying a replacement for years.
• Silence is Golden: Optimized aerodynamics mean less turbulence and noise, keeping your operation discreet.
• Energy Savings: Consumes only 108W at full power, which is highly efficient for the massive amount of air it moves.

Tricks to get the most out of it without overspending

If you want to make your setup even stealthier without buying a silencer, use sonoconnect (acoustic) ducting on both the intake and outtake. The Prima Klima is already quiet, but with insulated ducting, it becomes virtually inaudible outside the room.

Another pro tip: Use the low speed (420 m³/h) during the night cycle when lights are off. Plants transpire less and heat is lower, so you don't need the full 800 m³/h hurricane. This simple habit cuts your fan's electricity consumption significantly and extends the motor's lifespan.

Frequently Asked Questions

What size carbon filter do I need for this extractor?

You should always choose a carbon filter with a slightly higher capacity than the fan's maximum output. For this model, look for a filter rated at least 900 m³/h or 1000 m³/h with a 160mm flange to ensure no smells escape and the fan isn't choked.

Is it loud?

Compared to standard budget fans, it is very quiet due to its aerodynamic shape and quality bearings. However, at full speed (800 m³/h), the sound of rushing air is inevitable. Using acoustic ducting is the best way to silence the wind noise.

Can I use a dimmer or speed controller with it?

This model already has a built-in 2-speed switch, which is the most efficient way to control it. Using an external cheap voltage dimmer might cause the motor to hum. If you need precise percentage control, you might want to look at the Prima Klima TC (Temperature Controlled) or EC lines.

Personal Experience of Pevgrow’s CEO (Alan)

"I've seen plenty of growers try to cut corners on extraction, and it always ends the same way: panic in the middle of July when the temperature hits 35°C inside the tent. For me, the Prima Klima 2-Speed 160mm is the 'sweet spot' for 1.2m x 1.2m or even slightly larger tents. It's not the most expensive fan on the market, but it performs like a top-tier industrial unit."

"What I really appreciate is the peace of mind. You turn it on, and you know it's going to run for years. The 2-speed switch is a feature I use constantly—low for the seedlings and early veg, high for the heavy flowering stage. It pays for itself just by not having to buy a new fan every year."
