Extractor

Extraction fans for controlled indoor growing

Effective air extraction prevents heat build-up, excess humidity and CO2 depletion in your grow space. A properly sized extractor fan creates slight negative pressure, drawing stale air through a carbon filter to neutralise odours before exhausting it outside — a must for discreet urban grows across Belgium.

Browse inline duct fans from trusted brands such as Prima Klima, Vents and RVK, available from 100 mm to 200 mm and beyond. Speed-controllable models let you fine-tune airflow per growth stage, while EC-motor extractors cut energy use by up to 30 percent with quieter operation.

Our extractor range

At Plant & Flower, your Belgian grow shop since 2011, we stock a complete range of extractor fans from Prima Klima, Vents Quietline and other renowned brands for indoor cultivation. Air extraction is essential for a healthy grow climate: without sufficient extraction, heat, humidity and CO2 depletion compound rapidly and tank your yields. Combined with a carbon filter, your extractor also neutralises odours and creates the negative pressure needed for fully discreet cultivation. It's the heart of any well-functioning ventilation system.

Types of extractors and their characteristics

Inline duct fans are the standard for grow spaces: cylindrical, installed directly into the ducting system with minimal footprint. Three main families dominate the market: traditional AC motors (budget-friendly upfront), AC dual-speed like the Prima Klima 2-speed range (simple flexibility), and EC motors with electronic commutation (up to 30 % lower consumption, quieter, longer lifespan).

Technical specifications that matter

Capacity 100-1000 m³/h: choose based on tent volume × 60 + 20 % margin
Standard diameters: 100, 125, 150 and 200 mm to fit existing ducting
Noise level: 28-50 dB depending on model and speed (Vents Quietline and RVK among the quietest)
EC vs AC motor: EC more expensive upfront but 25-40 % energy savings, lifespan 50,000+ h vs 30,000 h
Speed control: separate controller for AC, integrated for EC (potentiometer or 0-10 V)
Built-in thermostat: Prima Klima Thermostat models adjust automatically based on temperature

Choosing the right extractor

The sizing rule is simple: tent volume (L × W × H in m³) × 60 + 20 % margin for the resistance of the carbon filter and duct reducers. For a 1 × 1 m tent, an inline fan Ø100 mm 105 m³/h is enough. A 1.2 × 1.2 m tent calls for a Ø125 mm 185 m³/h or the Ø150 mm 300 m³/h with margin. For a 2.4 × 1.2 m tent, the Prima Klima 800 m³/h covers the requirements. Want integrated speed control? The Prima Klima 2-speed 420-800 m³/h adjusts extraction to the growth phase. For maximum noise discretion in a residential setting, the Vents Quietline Ø125 197 m³/h ranks among the quietest on the market. Use quality hose clamps to prevent air leakage that compromises efficiency.

Installation and noise control

The standard installation order: carbon filter → ducting → extractor → ducting → exhaust. This pull configuration ensures the extractor processes clean, filtered air, extending its operational life. Mount the extractor on rubber suspension brackets or elastic hangers to dampen vibrations transmitted to the building structure. Use insulated ducting on sections close to living areas to minimise sound transmission. For maximum discretion in residential environments, place the extractor in a soundproof enclosure or separate room.

FAQ - Frequently asked questions about extractors

Which extractor do I need for my grow tent?

For a standard 1.2 × 1.2 × 2 m grow tent, you need an extractor of 200-250 m³/h to achieve 60 air changes per hour including filter compensation. Larger 2.4 × 1.2 × 2 m tents require 400-500 m³/h capacity. Always factor in 20-30 % extra capacity for resistance from carbon filters and ducting.

What's the difference between AC and EC motors?

EC motors (electronically commutated) are 25-40 % more energy-efficient than traditional AC motors and produce less heat and noise. They feature built-in speed control and a longer lifespan of 50,000+ hours versus 30,000 hours for AC motors. The upfront premium pays back within 1-2 years.

How much noise does an extractor produce?

Modern inline fans produce 35-50 dB depending on capacity and speed setting, comparable to a refrigerator. Quiet models like Vents Quietline or Prima Klima at low speed reach 28-35 dB. Use sound-dampening ducting and rubber mounting brackets to minimise vibrations transmitted to the structure.

How often should I replace my carbon filter?

Carbon filters last 12-18 months under continuous use, depending on humidity. High humidity (> 70 %) significantly shortens lifespan. Replace the filter as soon as you perceive odours or the extractor becomes louder due to the extra resistance of a saturated filter.

Can I dim an extractor without a speed controller?

Traditional AC motors cannot be safely dimmed without an appropriate controller — always use a compatible transformer dimmer or triac dimmer. EC motors usually feature built-in speed control via potentiometer or 0-10 V signal. Speed control lets you reduce noise at night and save energy during less intensive periods.

How do I install the ventilation chain correctly?

The standard order is: carbon filter inside the tent → ducting → extractor (outside the tent or in a soundproof box) → ducting → exhaust. This pull configuration creates negative pressure inside the tent so odours cannot escape. Check all connections with aluminium tape and hose clamps: every leak drastically reduces system efficiency.
