low-noiseIP44mixed-flow

Low profile “Mixed-flow” fans with sound-absorbent insulation, extremely quiet, fan casing manufactured in plastic material, with a specially designed internal skin to direct the sound waves at the right angle for them to be captured by sound-absorbent material, fitted with flexible rubber seals on the inlet and outlet to absorb vibrations, with an external connection box, a body that can be removed without dismantling the adjacent ducting and therefore facilitating any installation or maintenance. Brushless EC motor, high efficiency and low consumption, suitable for single phase supply 230V±15%/50-60Hz, IP44, thermal overload protection. Eqquiped with a variable airflow sensor that allows the creation of a plug&play system of constant air volume (CAV). Airflow set point adjustable in terminal box. Analogue input to control the fan with an external signal 0-10V. Prepared to work from -20 to +40ºC. Low profile - compact Low profile fans TD SILENT ECOWATT CAV are ideal for installations where space is very limited, especially in ceiling voids.
