Applications – Supply and exhaust systems for various premises. The steel casing provides reliable operation in case of outdoor installation. For premises with high requirements to the noise level we suggest units in low-noise modification (VKM…Q).
The fan casing is made of steel with polymeric coating. For easy connection and operation the power cord with a plug can be provided (VKM…R).
The impeller with backward curved blades is powered by the single-phase motor with external rotor and overheating protection with automatic restart. Some standard sizes are available is high-powered modifications (VKMS). The motor is equipped with ball bearings for long service life designed for at least 40 000 hours. For precise features, safe operation and low noise, each turbine is dynamically balanced while assembly. Motor protection rating IP 44.
Smooth or step speed control is performed with thyristor or auto transformer controller. Several fans can be connected to one controller in case the total power and operating current do not exceed the controller rated values.
