S&P CACB-N ECOWATT-005-L ventilation box

CACB-N ECOWATT-005-L ventilation box. Self/hygro-regulating ventilation boxes, made of galvanized steel, certified 400ºC-1/2h for air extraction in case of fire and specially designed to maintain a constant pressure in the installation. They can be installed outdoors without the need for a weather cover (vertical discharge models do require a weather cover). Insulated versions (ISO models): Incorporate acoustic insulation in 25 mm glass wool (fire classification M0). Fully automatic operation: a pressure sensor, mounted as standard in the box, sends information to the frequency converter that adjusts the motor speed. This allows for maintaining a constant pressure in the duct network throughout the fan curve. The continuous adjustment of speed to the needs of the installation allows for a considerable reduction in consumption. The pressure level can be easily adjusted. Power supply 230V.
