Refurbished 1-speed air extractor: efficient ventilation at a smart price

A refurbished 1-speed air extractor is the perfect solution to ventilate your grow space without breaking the bank. These devices have been tested, serviced, and restored by us. They offer the same performance as a new model but at a much more accessible price. Frankly, for starting out or complementing an existing setup, it's a smart move.

Why choose a refurbished 1-speed air extractor

Ventilation is the heart of your indoor setup. A refurbished 1-speed extractor guarantees a constant and reliable flow, generally between 150 and 800 m3/h depending on the model. These devices have already proven their worth in the field before being refurbished. We disassemble them, check each component, replace what needs to be replaced, and test them again. The result: you get a perfectly functional extractor at 30-50% of the new price.

The advantage of 1-speed is its simplicity. No electronic variator that can break down, just a robust motor that runs at a constant speed. These refurbished extractors maintain their original efficiency: same airflow, same ability to evacuate heat and humidity. For a grow tent from 60x60cm to 120x120cm, a refurbished 250-400 m3/h model is more than sufficient.

How to choose your refurbished 1-speed extractor

The flow calculation is the basis: volume of your space x 60 for air renewal per minute. For a 100x100x200cm tent (2m3), aim for a minimum of 120 m3/h, but rather 200-250 m3/h to compensate for the resistance of the carbon filter. Refurbished 150mm models are perfect for medium spaces, while 125mm models are suitable for small setups.

Carefully check the condition of the casing and blades. A refurbished extractor must have been thoroughly cleaned and balanced. Bearings are often replaced during refurbishment, which guarantees silent operation. In terms of noise, expect 35-45 dB for a good refurbished model, equivalent to a whisper.

For installation, these extractors are mounted exactly like new ones: mounting flange, flexible duct, and clamps. Most accept an upstream carbon filter without issue. Just expect a 10-15% reduction in flow with a new, dense filter.

Frequently Asked Questions

What is the exact power of this refurbished 1-speed air extractor and is it sufficient for my 1m x 1m x 2m tent?

For a 2m3 tent, a refurbished 200-300 m3/h extractor is more than sufficient. Most refurbished 1-speed models develop between 150 and 500 m3/h depending on their diameter (100, 125, or 150mm). With 250 m3/h, you renew the air 125 times per hour, which is perfect for maintaining stable temperature and humidity. These extractors generally consume 35-65W depending on the size.

How do I install it in my indoor grow box with a carbon filter without losing airflow?

Installation is identical to a new one: fix the extractor at the top of the box with its flange, connect the carbon filter on the suction side with a short, rigid duct if possible. Avoid 90° elbows which reduce flow by 20-30%. A new filter causes a 15-20% flow loss in the first few months, then stabilizes. With a refurbished 300 m3/h extractor and a suitable filter, you maintain an effective 240-250 m3/h.

Is this refurbished extractor as quiet as a new one, especially at night?

A well-refurbished extractor regains its original sound level, i.e., 35-45 dB depending on the model. Bearings are often replaced during refurbishment, which eliminates parasitic vibrations. To further reduce noise, mount it on silent blocks and use an acoustic duct. At night, with these precautions, it will be almost inaudible from the next room.

What is the difference with a variable speed extractor for temperature and humidity regulation?

The refurbished 1-speed extractor runs continuously at the same speed, which guarantees constant ventilation but less precision in regulation. A variable speed model allows you to adjust the flow according to conditions, but costs 2-3 times more. For starting out or with a separate climate controller, the refurbished 1-speed does the job very well. You just need to correctly size the initial flow.

How do I maintain it regularly, especially since it's refurbished, to avoid breakdowns?

Maintenance of a refurbished extractor is identical to a new one: cleaning the blades every 3-6 months with a dry brush, checking the fixings and balancing. Avoid water on the motor; a damp cloth on the casing is sufficient. Monitor for abnormal vibrations that could indicate an unbalanced blade. With minimal maintenance, these refurbished extractors easily last 3-5 years in intensive use.
