The CVTR series fans are particularly recommended for use in systems that are required to change the air. Their
particular characteristic is their quietness, which makes then ideal in public rooms (dwellings, bars, restaurants,
gymnasia and offices) as well as industrial locations. Their low level of noise emission is due to the casing being
covered with phonoabsorbent material that enables a significant reduction in the level of the noise inevitably produced by the fan. The range includes various square inlet models in sizes from 180 to 450. The flow rates range
from 1000 m3/h to 15000 m3/h and with static pressures up to 3000 Pa. The fan has a dual inlet centrifuge, reverse
curved blades, and is coupled to the motor by means of trapezoidal belts and pulleys. The fan and the motor are
mounted on anti-vibrating supports. Maximum operating temperature is 40°C.
