ROOF-CM fans are characterized by the backward curved blade high efficiency impeller and extremely wide radius inlet cone guarantee of high capacities and pressures with limited noise levels. The accuracy of the design of the cap, with square section, confers to the fan a particularly pleasant aesthetic impact, easy to be installed in every architectural contest guarantying the optimum cooling of the motor. The protection guard in steel rod offers less resistance to the airflow when compared to the grids normally used and the best self-cleaning effect. The electric motor is manufactured according to the international standards guarantee of reliability and sturdiness, ease of maintenance and replacement.
