Noise-isolating fan in an MDF box. Draws warm and moist air from the grow area. The fan should be sized for an airflow 30 to 50 times the volume of your grow room. You can then effectively control the fan speed with other devices depending on the temperature and humidity. You will not only use additional potential of the Airfan, but also further reduce possible noise to a minimum. The Soft-BOX 2500 m3/h fan is mounted in MDF boards with insulating foam that covers the interior and thus reduces the noise produced by the fan. - Suitable outlet fan for a room with dimensions of about 20 sq.m. - A suitable filter for this fan can be viewed here.
