Extractor Fans

What Do Extractor Fans Do?

Extractor fans are essential for regulating air quality and temperature in grow rooms or enclosed spaces. They remove stale air, excess moisture, and unwanted odours while providing fresh air to promote plant growth. For hydroponic setups, extractor fans play a key role in controlling humidity and preventing mould or mildew.

How Does an Extractor Fan Work?

Extractor fans use a motorized fan blade to draw air out of space and push it through ducting or a filter system. In grow rooms, in-line extractor fans are common because they connect directly to ventilation ducts, creating a streamlined airflow path. The fan pulls air through a carbon filter (if attached), eliminating odours before expelling it outside.

How Much Are Extractor Fans?

Prices for extractor fans vary depending on size, power, and features. Box extractor fans, which are compact and easy to install, typically cost between £250 to £650. For larger setups, high-powered in-line extractor fans with advanced features like speed control or noise reduction can range from £10 to £350.

EC vs. AC Fans: Comparison

When choosing the best extractor fans, understanding the difference between EC (Electronically Commutated) and AC (Alternating Current) fans is crucial. EC fans are more energy-efficient, offering precise speed control and lower running costs. In contrast, AC fans are more affordable but less efficient. Although they are often noisier, AC fans are still popular for basic setups due to their reliability and lower upfront costs.

Are Extractor Fans Expensive to Run?

Running costs depend on fan efficiency, usage time, and energy rates. EC extractor fans are cheaper to run long-term because they consume less energy and can be adjusted for optimal performance. AC fans, though cheaper upfront, often lead to higher energy bills. Investing in an EC fan with variable speed control can save growers money over time.

How Long Do Extractor Fans Last?

The lifespan of an extractor fan largely depends on the quality of the fan and its maintenance. On average, the best extractor fans last 4-6 years, however, as electrical goods this can be highly variable. Regular cleaning and maintenance, such as clearing dust from fan blades and replacing worn filters, can extend the life of your fan. Proper installation and avoiding overloading your fan by using it beyond its rated capacity are also critical for longevity.
