Can-Fan RK 250/830 Extractor Fan 1 Speed

Buy Can-Fan RK 250/830 1 Speed Extractor

The Can-Fan RK 250/830 1 Speed Extractor belongs to the range of centrifugal extractors with backward-curved impeller, a geometry that improves available duct pressure and reduces perceived noise. The unit is housed in robust technical plastic that dampens vibrations and makes it easy to mount on a wall, ceiling, or cabinet structure.

The 250 mm outlet allows direct connection with carbon filters, silencers, and flexible or rigid ducts. It integrates a thermal switch that disconnects the motor if the temperature exceeds the safety threshold, a key feature for installations that operate for many hours at a time.

This is a 1 speed model that allows regulation via a compatible voltage regulator, useful for fine-tuning airflow in different seasons or time slots. With 100 W nominal power and 0.5 A current, it offers reliable and efficient performance. Available at Hydroponics Blanes, Grow Shop in Spain, with discreet shipping and advice for sizing ventilation, filtration, and climate control along with other cannabis growing accessories and options for cheap indoor grow tents.

Indoor Growing Can-Fan RK 250/830 1 Speed Extractor

In indoor growing environments, proper extraction makes the difference: it stabilizes temperature, reduces excessive humidity, provides CO₂ renewal, and helps with odor control. The Can-Fan RK 250/830 1 Speed Extractor moves 830 m³/h, an ideal value for compact rooms or large tents with medium thermal loads, especially when the circuit includes a carbon filter and duct sections with bends.

What is the Can-Fan RK 250/830 1 Speed Extractor for?

• Extract stale air loaded with heat, humidity, and aromatic compounds.
• Maintain a stable climate during growth and flowering phases.
• Work with carbon filters without drastic loss of airflow thanks to the backward-curved impeller.
• Increase gas exchange improving transpiration and assimilation.

Indoor growing accessory Can-Fan RK 250/830 1 Speed Extractor

Among cannabis growing accessories, this extractor stands out for its easy installation, balanced dimensions for 250 mm, and low noise level of ≈47 dB(A) in well-sealed setups. Approximate weight 3.1 kg, stable continuous operation, and compatibility with controllers that allow ventilation to be adjusted to the actual needs of the crop.

What is the Can-Fan RK 250/830 1 Speed Extractor used for?

It is used to evacuate heat from lights, lower relative humidity at night or after heavy watering, renew CO₂, and help with odor filtration. It works very well in large tents and rooms with medium duct lengths, where extra pressure is needed to overcome losses in filters, silencers, and bends. Perfect for projects seeking a homogeneous environment and fewer hot spots.

How to use Can-Fan RK 250/830 1 Speed Extractor

1) Calculate required airflow: volume (m³) × air changes/h (e.g., 30–60).
2) Place at the top of the room to extract accumulated hot air.
3) Connect to 250 mm duct and to a carbon filter of the same diameter if necessary.
4) Minimize bends and excessive sections; seal joints with clamps and aluminum tape.
5) Optional: add a certified voltage regulator to adjust airflow according to season or schedule.
6) Check for airtightness and test draft by hand or with an anemometer; check vibrations and fixings periodically.
7) Keep filter and ducts clean to maintain airflow and noise level.

Advantages of using Can-Fan RK 250/830 1 Speed Extractor
