2 x RUCK Fans 100mm/4 Inch Low Power Version (230m3/hour) & High Power Version (230m3/hour) ?

2 x RUCK Fans 100mm/4 Inch Low Power Version (230m3/hour) & High Power Version (230m3/hour) The top-quality, German-made RUCK fans are now branded CAN but are still some of the most reliable available and are perfectly suited for inline extraction and intake. In any indoor growing environment the flow of air is vital, both to remove unwanted heat from lighting and to provide fresh air for the plants. For each size of RUCK there is a high-powered ‘L’ model which has a higher torque motor and is better suited for use with a carbon filter as the filter will reduce airflow by approximately 15-20%. The standard models are ideal for use as intake fans or for extraction in smaller growing environments where a carbon filter is not required. Noise can often be an issue when you have fans running throughout the day, and while every environment has different acoustics, the lower powered fans will always be quieter than the high-powered version. 2-3m cable also supplied for each fan along with original wall mounting brackets
