KROV fans feature a low-profi le casing with air exhaust to atmosphere upwards and low weight; special protection of the serviced premise from atmospheric precipitation is provided.

These fans use two modifi cations of impellers with six (KROV6) and nine (KROV9) backward-curved blades of a special shape. The fans create high fl ow, high static pressure and low noise. The impellers are mounted directly on the motor shaft and consume power as the fl ow rate increases without overloading the motor. Fans are equipped with single-speed motors or motors that allow frequency control of the rotation speed.

Design:

• general purpose industrial (N);
• corrosion-resistant (CR1);
