Radial roof ventilators with upward flow outlet UKROS

UKROS® fans use an improved impeller with backward curved blades, toroidal inlet with a larger inlet diameter.
The fundamental difference of UKROS is the upward flare system with hinged protective pockets.
The impeller is mounted directly on the motor shaft. The fans are equipped with high quality 3-phase asynchronous single-speed motors. Frequency regulation of rotation speed is possible.
UKROS® fans have a well-thought-out design of the casing with a 4- and 6-sided shape of the motor casing with a movable and very strong built-in gravity-type check valve, forming a flare discharge. Maximum protection against snow and rain is provided (exceeds the protection of CROV and CROS fans). .
