Noise-isolating fan in an MDF box. Draws warm and moist air from growing areas. 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 the full potential of the Airfan, but also further reduce possible noise to a minimum. The ISO-BOX 1500 m3/h fan is mounted in MDF boards with insulating foam that covers the interior and thus reduces the noise produced by the fan. Features: Connections: 2x 250 mm (IN / OUT) Capacity: 1500m³ / h Speed range (m3 / h): 300 - 1520 Power supply: 230 v / 50 Hz Power: 414W Noise level (dB): 36.7 Temperature range: -30°C to 70°C Protection class: IP44
