S&P CACB-N ECOWATT-005-L Ventilation Box

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